+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"
+      replaced with your own identifying information. (Don't include
+      the brackets!)  The text should be enclosed in the appropriate
+      comment syntax for the file format. We also recommend that a
+      file or class name and description of purpose be included on the
+      same "printed page" as the copyright notice for easier
+      identification within third-party archives.

It darkens creases, cavities and surfaces\n * that are close to each other, which tend to be occluded from ambient light and appear darker.\n *\n * The animated GIF above shows the effect as we repeatedly enable and disable SAO. When SAO is enabled, we can see darkening\n * in regions such as the corners, and the crevices between stairs. This increases the amount of detail we can see when ambient\n * light is high, or when objects have uniform colors across their surfaces. Run the example to experiment with the various\n * SAO configurations.\n *\n * xeokit's implementation of SAO is based on the paper [Scalable Ambient Obscurance](https://research.nvidia.com/sites/default/files/pubs/2012-06_Scalable-Ambient-Obscurance/McGuire12SAO.pdf).\n *\n * ## Caveats\n *\n * Currently, SAO only works with perspective and orthographic projections. Therefore, to use SAO, make sure {@link Camera#projection} is\n * either \"perspective\" or \"ortho\".\n *\n * {@link SAO#scale} and {@link SAO#intensity} must be tuned to the distance\n * between {@link Perspective#near} and {@link Perspective#far}, or the distance\n * between {@link Ortho#near} and {@link Ortho#far}, depending on which of those two projections the {@link Camera} is currently\n * using. Use the [live example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter) to get a\n * feel for that.\n *\n * ## Usage\n *\n * In the example below, we'll start by logging a warning message to the console if SAO is not supported by the\n * system.\n *\n *Then we'll enable and configure SAO, position the camera, and configure the near and far perspective and orthographic\n * clipping planes. Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\",\n *     transparent: true\n * });\n *\n * const sao = viewer.scene.sao;\n *\n * if (!sao.supported) {\n *     sao.warn(\"SAO is not supported on this system - ignoring SAO configs\")\n * }\n *\n * sao.enabled = true; // Enable SAO - only works if supported (see above)\n * sao.intensity = 0.20;\n * sao.bias = 0.5;\n * sao.scale = 1.0;\n * sao.minResolution = 0.0;\n * sao.numSamples = 10;\n * sao.kernelRadius = 100;\n * sao.blendCutoff = 0.1;\n *\n * const camera = viewer.scene.camera;\n *\n * camera.eye = [3.69, 5.83, -23.98];\n * camera.look = [84.31, -29.88, -116.21];\n * camera.up = [0.18, 0.96, -0.21];\n *\n * camera.perspective.near = 0.1;\n * camera.perspective.far = 2000.0;\n *\n * camera.ortho.near = 0.1;\n * camera.ortho.far = 2000.0;\n * camera.projection = \"perspective\";\n *\n * const xktLoader = new XKTLoaderPlugin(viewer);\n *\n * const model = xktLoader.load({\n *     id: \"myModel\",\n *     src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n *     metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n *     edges: true\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter)]\n *\n * ## Efficiency\n *\n * SAO can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\n * it's recommended to use a low value for {@link SAO#kernelRadius}.  A low radius will sample pixels that are close\n * to the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\n * objects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  SAO for close objects\n * is more expensive than for objects far away, that occupy fewer pixels on the canvas.\n *\n * ## Selectively enabling SAO for models\n *\n * When loading multiple models into a Scene, we sometimes only want SAO on the models that are actually going to\n * show it, such as the architecture or structure, and not show SAO on models that won't show it well, such as the\n * electrical wiring, or plumbing.\n *\n * To illustrate, lets load some of the models for the West Riverside Hospital. We'll enable SAO on the structure model,\n * but disable it on the electrical and plumbing.\n *\n * This will only apply SAO to those models if {@link SAO#supported} and {@link SAO#enabled} are both true.\n *\n * Note, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\n * process, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\n * pools of scratch memory.\n *\n * ````javascript\n * const structure = xktLoader.load({\n *      id: \"structure\",\n *      src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n *      metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n *      edges: true,\n *      saoEnabled: true\n *  });\n *\n *  structure.on(\"loaded\", () => {\n *\n *      const electrical = xktLoader.load({\n *          id: \"electrical\",\n *          src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n *          metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n *          edges: true\n *      });\n *\n *      electrical.on(\"loaded\", () => {\n *\n *          const plumbing = xktLoader.load({\n *              id: \"plumbing\",\n *              src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n *              metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n *                  edges: true\n *              });\n *          });\n *      });\n * });\n * ````\n *\n * ## Disabling SAO while camera is moving\n *\n * For smoother interaction with large models on low-power hardware, we can disable SAO while the {@link Camera} is moving:\n *\n * ````javascript\n * const timeoutDuration = 150; // Milliseconds\n * var timer = timeoutDuration;\n * var saoDisabled = false;\n *\n * const onCameraMatrix = scene.camera.on(\"matrix\", () => {\n *     timer = timeoutDuration;\n *     if (!saoDisabled) {\n *         scene.sao.enabled = false;\n *         saoDisabled = true;\n *     }\n * });\n *\n * const onSceneTick = scene.on(\"tick\", (tickEvent) => {\n *     if (!saoDisabled) {\n *         return;\n *     }\n *     timer -= tickEvent.deltaTime; // Milliseconds\n *     if (timer <= 0) {\n *         if (saoDisabled) {\n *             scene.sao.enabled = true;\n *             saoDisabled = false;\n *         }\n *     }\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#techniques_nonInteractiveQuality)]\n ",

Use the [live example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter) to get a\n * feel for that.\n *\n * ## Usage\n *\n * In the example below, we'll start by logging a warning message to the console if SAO is not supported by the\n * system.\n *\n *Then we'll enable and configure SAO, position the camera, and configure the near and far perspective and orthographic\n * clipping planes. Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\",\n *     transparent: true\n * });\n *\n * const sao = viewer.scene.sao;\n *\n * if (!sao.supported) {\n *     sao.warn(\"SAO is not supported on this system - ignoring SAO configs\")\n * }\n *\n * sao.enabled = true; // Enable SAO - only works if supported (see above)\n * sao.intensity = 0.15;\n * sao.bias = 0.5;\n * sao.scale = 1.0;\n * sao.minResolution = 0.0;\n * sao.numSamples = 10;\n * sao.kernelRadius = 100;\n * sao.blendCutoff = 0.1;\n *\n * const camera = viewer.scene.camera;\n *\n * camera.eye = [3.69, 5.83, -23.98];\n * camera.look = [84.31, -29.88, -116.21];\n * camera.up = [0.18, 0.96, -0.21];\n *\n * camera.perspective.near = 0.1;\n * camera.perspective.far = 2000.0;\n *\n * camera.ortho.near = 0.1;\n * camera.ortho.far = 2000.0;\n * camera.projection = \"perspective\";\n *\n * const xktLoader = new XKTLoaderPlugin(viewer);\n *\n * const model = xktLoader.load({\n *     id: \"myModel\",\n *     src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n *     metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n *     edges: true\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter)]\n *\n * ## Efficiency\n *\n * SAO can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\n * it's recommended to use a low value for {@link SAO#kernelRadius}.  A low radius will sample pixels that are close\n * to the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\n * objects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  SAO for close objects\n * is more expensive than for objects far away, that occupy fewer pixels on the canvas.\n *\n * ## Selectively enabling SAO for models\n *\n * When loading multiple models into a Scene, we sometimes only want SAO on the models that are actually going to\n * show it, such as the architecture or structure, and not show SAO on models that won't show it well, such as the\n * electrical wiring, or plumbing.\n *\n * To illustrate, lets load some of the models for the West Riverside Hospital. We'll enable SAO on the structure model,\n * but disable it on the electrical and plumbing.\n *\n * This will only apply SAO to those models if {@link SAO#supported} and {@link SAO#enabled} are both true.\n *\n * Note, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\n * process, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\n * pools of scratch memory.\n *\n * ````javascript\n * const structure = xktLoader.load({\n *      id: \"structure\",\n *      src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n *      metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n *      edges: true,\n *      saoEnabled: true\n *  });\n *\n *  structure.on(\"loaded\", () => {\n *\n *      const electrical = xktLoader.load({\n *          id: \"electrical\",\n *          src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n *          metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n *          edges: true\n *      });\n *\n *      electrical.on(\"loaded\", () => {\n *\n *          const plumbing = xktLoader.load({\n *              id: \"plumbing\",\n *              src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n *              metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n *                  edges: true\n *              });\n *          });\n *      });\n * });\n * ````\n *\n * ## Disabling SAO while camera is moving\n *\n * For smoother interaction with large models on low-power hardware, we can disable SAO while the {@link Camera} is moving:\n *\n * ````javascript\n * const timeoutDuration = 150; // Milliseconds\n * var timer = timeoutDuration;\n * var saoDisabled = false;\n *\n * const onCameraMatrix = scene.camera.on(\"matrix\", () => {\n *     timer = timeoutDuration;\n *     if (!saoDisabled) {\n *         scene.sao.enabled = false;\n *         saoDisabled = true;\n *     }\n * });\n *\n * const onSceneTick = scene.on(\"tick\", (tickEvent) => {\n *     if (!saoDisabled) {\n *         return;\n *     }\n *     timer -= tickEvent.deltaTime; // Milliseconds\n *     if (timer <= 0) {\n *         if (saoDisabled) {\n *             scene.sao.enabled = true;\n *             saoDisabled = false;\n *         }\n *     }\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#techniques_nonInteractiveQuality)]\n ",

Use the [live example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter) to get a\n * feel for that.\n *\n * ## Usage\n *\n * In the example below, we'll start by logging a warning message to the console if SAO is not supported by the\n * system.\n *\n *Then we'll enable and configure SAO, position the camera, and configure the near and far perspective and orthographic\n * clipping planes. Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\",\n *     transparent: true\n * });\n *\n * const sao = viewer.scene.sao;\n *\n * if (!sao.supported) {\n *     sao.warn(\"SAO is not supported on this system - ignoring SAO configs\")\n * }\n *\n * sao.enabled = true; // Enable SAO - only works if supported (see above)\n * sao.intensity = 0.20;\n * sao.bias = 0.5;\n * sao.scale = 1.0;\n * sao.minResolution = 0.0;\n * sao.numSamples = 10;\n * sao.kernelRadius = 100;\n * sao.blendCutoff = 0.1;\n *\n * const camera = viewer.scene.camera;\n *\n * camera.eye = [3.69, 5.83, -23.98];\n * camera.look = [84.31, -29.88, -116.21];\n * camera.up = [0.18, 0.96, -0.21];\n *\n * camera.perspective.near = 0.1;\n * camera.perspective.far = 2000.0;\n *\n * camera.ortho.near = 0.1;\n * camera.ortho.far = 2000.0;\n * camera.projection = \"perspective\";\n *\n * const xktLoader = new XKTLoaderPlugin(viewer);\n *\n * const model = xktLoader.load({\n *     id: \"myModel\",\n *     src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n *     metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n *     edges: true\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter)]\n *\n * ## Efficiency\n *\n * SAO can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\n * it's recommended to use a low value for {@link SAO#kernelRadius}.  A low radius will sample pixels that are close\n * to the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\n * objects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  SAO for close objects\n * is more expensive than for objects far away, that occupy fewer pixels on the canvas.\n *\n * ## Selectively enabling SAO for models\n *\n * When loading multiple models into a Scene, we sometimes only want SAO on the models that are actually going to\n * show it, such as the architecture or structure, and not show SAO on models that won't show it well, such as the\n * electrical wiring, or plumbing.\n *\n * To illustrate, lets load some of the models for the West Riverside Hospital. We'll enable SAO on the structure model,\n * but disable it on the electrical and plumbing.\n *\n * This will only apply SAO to those models if {@link SAO#supported} and {@link SAO#enabled} are both true.\n *\n * Note, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\n * process, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\n * pools of scratch memory.\n *\n * ````javascript\n * const structure = xktLoader.load({\n *      id: \"structure\",\n *      src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n *      metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n *      edges: true,\n *      saoEnabled: true\n *  });\n *\n *  structure.on(\"loaded\", () => {\n *\n *      const electrical = xktLoader.load({\n *          id: \"electrical\",\n *          src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n *          metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n *          edges: true\n *      });\n *\n *      electrical.on(\"loaded\", () => {\n *\n *          const plumbing = xktLoader.load({\n *              id: \"plumbing\",\n *              src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n *              metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n *                  edges: true\n *              });\n *          });\n *      });\n * });\n * ````\n *\n * ## Disabling SAO while camera is moving\n *\n * For smoother interaction with large models on low-power hardware, we can disable SAO while the {@link Camera} is moving:\n *\n * ````javascript\n * const timeoutDuration = 150; // Milliseconds\n * var timer = timeoutDuration;\n * var saoDisabled = false;\n *\n * const onCameraMatrix = scene.camera.on(\"matrix\", () => {\n *     timer = timeoutDuration;\n *     if (!saoDisabled) {\n *         scene.sao.enabled = false;\n *         saoDisabled = true;\n *     }\n * });\n *\n * const onSceneTick = scene.on(\"tick\", (tickEvent) => {\n *     if (!saoDisabled) {\n *         return;\n *     }\n *     timer -= tickEvent.deltaTime; // Milliseconds\n *     if (timer <= 0) {\n *         if (saoDisabled) {\n *             scene.sao.enabled = true;\n *             saoDisabled = false;\n *         }\n *     }\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#techniques_nonInteractiveQuality)]\n ",

Those Entities will have {@link Entity#isObject} set ````true```` and will be registered by {@link Entity#id} in {@link Scene#objects}.\n * * When loading, can set the World-space position, scale and rotation of each model within World space, along with initial properties for all the model's {@link Entity}s.\n *\n * ## Metadata\n *\n * GLTFLoaderPlugin can also load an accompanying JSON metadata file with each model, which creates a {@link MetaModel} corresponding\n * to the model {@link Entity} and a {@link MetaObject} corresponding to each object {@link Entity}.\n *\n * Each {@link MetaObject} has a {@link MetaObject#type}, which indicates the classification of its corresponding {@link Entity}. When loading\n * metadata, we can also provide GLTFLoaderPlugin with a custom lookup table of initial values to set on the properties of each type of {@link Entity}. By default, GLTFLoaderPlugin\n * uses its own map of default colors and visibilities for IFC element types.\n *\n * ## Quality Setting\n *\n * By default, GLTFLoaderPlugin will load a high-performance scene representation that's optimized for low memory usage and\n * optimal rendering. The high-performance representation renders large numbers of objects efficiently, using geometry\n * batching and instancing, with simple Lambertian shading that ignores any textures and realistic materials in the glTF.\n *\n * Specifying ````performance:false```` to {@link GLTFLoaderPlugin#load} will internally load a heavier scene\n * representation comprised of {@link Node}, {@link Mesh}, {@link Geometry}, {@link Material} and {@link Texture} components,\n * that will exactly preserve the materials specified in the glTF. Use this when you want to load a model for a realistic preview,\n * maybe using PBR etc.\n *\n * We tend to use the default ````performance:true```` setting for CAD and BIM models, where structure is more important that\n * surface appearance.\n *\n * Publically, GLTFLoaderPlugin creates the same {@link Entity}s for both levels of performance. Privately, however, it implements\n * {@link Entity}s using two different sets of concrete subtypes, for its two different internally-managed scene representations.\n *\n * ## Usage\n *\n * In the example below we'll load the Schependomlaan model from a [glTF file](http://xeokit.github.io/xeokit-sdk/examples/models/gltf/schependomlaan/), along\n * with an accompanying JSON [IFC metadata file](http://xeokit.github.io/xeokit-sdk/examples/metaModels/schependomlaan/).\n *\n * This will create a bunch of {@link Entity}s that represents the model and its objects, along with a {@link MetaModel} and {@link MetaObject}s\n * that hold their metadata.\n *\n * Since this model contains IFC types, the GLTFLoaderPlugin will set the initial colors of object {@link Entity}s according\n * to the standard IFC element colors in the GLTFModel's current map. Override that with your own map via property {@link GLTFLoaderPlugin#objectDefaults}.\n *\n * Read more about this example in the user guide on [Viewing BIM Models Offline](https://github.com/xeokit/xeokit-sdk/wiki/Viewing-BIM-Models-Offline).\n *\n * We're leaving ````performance: true```` since our model has many objects and we're not interested in realistic rendering.\n *\n * [[Run this example](http://xeokit.github.io/xeokit-sdk/examples/#BIMOffline_glTF_OTCConferenceCenter)]\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {GLTFLoaderPlugin} from \"../src/plugins/GLTFLoaderPlugin/GLTFLoaderPlugin.js\";\n *\n * //------------------------------------------------------------------------------------------------------------------\n * // 1.

Conversely, orbiting the Camera causes the NavCube to rotate accordingly.\n * * The faces of the NavCube are aligned with the Viewer's {@link Scene}'s World-space coordinate axis. Clicking on a face moves\n * the Camera to look at the entire Scene along the corresponding axis. Clicking on an edge or a corner looks at\n * the entire Scene along a diagonal.\n * * The NavCube can be configured to either jump or fly the Camera to each new position. We can configure how tightly the\n * NavCube fits the Scene to view, and when flying, we can configure how fast it flies. We can also configure whether the\n * NavCube fits all objects to view, or just the currently visible objects. See below for a usage example.\n * * Clicking the NavCube also sets {@link CameraControl#pivotPos} to the center of the fitted objects.\n *\n * ## Usage\n *\n * In the example below, we'll create a Viewer and add a NavCubePlugin, which will create a NavCube gizmo in the canvas\n * with the given ID. Then we'll use the {@link XKTLoaderPlugin} to load a model into the Viewer's Scene.

Triangles in STL are disjoint, where each triangle has its own separate vertex positions, normals and\n * (optionally) colors. This means that you can have gaps between triangles in an STL model. Normals for each triangle\n * are perpendicular to the triangle's surface, which gives the model a faceted appearance by default.\n *\n * The ```smoothNormals``` parameter causes the plugin to recalculate the STL normals, so that each normal's direction is\n * the average of the orientations of the triangles adjacent to its vertex. When smoothing, each vertex normal is set to\n * the average of the orientations of all other triangles that have a vertex at the same position, excluding those triangles\n * whose direction deviates from the direction of the vertice's triangle by a threshold given in\n * the ````smoothNormalsAngleThreshold```` loading parameter. This makes smoothing robust for hard edges.\n *\n * ## Creating Entities for Objects\n *\n * An STL model is normally a single mesh, however providing a ````splitMeshes```` parameter when loading\n * will create a separate object {@link Entity} for each group of faces that share the same vertex colors. This option\n * only works with binary STL files.\n *\n * See the {@link STLLoaderPlugin#load} method for more info on loading options.\n *\n * ## Usage\n *\n * In the example below, we'll use an STLLoaderPlugin to load an STL model of a spur gear. When the model has loaded,\n * we'll use the {@link CameraFlightAnimation} to fly the {@link Camera} to look at boundary of the model. We'll\n * then get the model's {@link Entity} from the {@link Scene} and highlight the whole model.\n *\n *  * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#loading_STL_SpurGear)]\n *\n * ````javascript\n * // Create a xeokit Viewer\n * const viewer = new Viewer({\n *      canvasId: \"myCanvas\"\n * });\n *\n * // Add an STLLoaderPlugin to the Viewer\n * var plugin = new STLLoaderPlugin(viewer);\n *\n * // Load the STL model\n * var model = plugin.load({ // Model is an Entity\n *      id: \"myModel\",\n *      src: \"./models/stl/binary/spurGear.stl\",\n *      scale: [0.1, 0.1, 0.1],\n *      rotate: [90, 0, 0],\n *      translate: [100,0,0],\n *      edges: true,\n *      smoothNormals: true,                // Default\n *      smoothNormalsAngleThreshold: 20,    // Default\n *      splitMeshes: true                   // Default\n * });\n *\n * // When the model has loaded, fit it to view\n * model.on(\"loaded\", function() { // Model is an Entity\n *      viewer.cameraFlight.flyTo(model);\n * });\n *\n * // Find the model Entity by ID\n * model = viewer.scene.models[\"myModel\"];\n *\n * // Update properties of the model Entity\n * model.highlight = [1,0,0];\n *\n * // Destroy the model Entity\n * model.destroy();\n * ````\n *\n * ## Loading from a Pre-Loaded STL File\n *\n * If we already have our STL file in memory (perhaps pre-loaded, or even generated in-client), then we can just pass that\n * file data straight into the {@link STLLoaderPlugin#load} method.

Then, once the model\n * has loaded, we'll add it manually using {@link TreeViewPlugin#addModel}.\n *\n * ````javascript\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"myTreeViewContainer\"),\n *      autoAddModels: false  // <<---------------- Don't auto-add models\n * });\n *\n * const xktLoader = new XKTLoaderPlugin(viewer);\n *\n * const model = xktLoader.load({\n *     id: \"myModel\",\n *     src: \"./models/xkt/schependomlaan/schependomlaan.xkt\",\n *     metaModelSrc: \"./metaModels/schependomlaan/metaModel.json\",\n *     edges: true\n * });\n *\n * model.on(\"loaded\", () => {\n *      treeView.addModel(model.id);\n * });\n * ````\n *\n * Adding models manually also allows us to set some options for the model. For example, the ````rootName```` option allows us to provide a custom name for\n * the root node, which is sometimes desirable when the model's \"IfcProject\" element's name is not suitable:\n *\n * ````javascript\n * model.on(\"loaded\", () => {\n *      treeView.addModel(model.id, {\n *          rootName: \"Schependomlaan Model\"\n *      });\n * });\n * ````\n *\n * ## Initially Expanding the Hierarchy\n *\n * We can also configure TreeViewPlugin to initially expand each model's nodes to a given depth.\n *\n * Let's automatically expand the first three nodes from the root, for every model added:\n *\n * ````javascript\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"myTreeViewContainer\"),\n *      autoExpandDepth: 3\n * });\n * ````\n *\n * ## Showing a Node by ID\n *\n * We can show a given node using its ID. This causes the TreeViewPlugin to collapse, then expand and scroll the node into view, then highlight the node.\n *\n * See the documentation for the {@link TreeViewPlugin#showNode} method for more information, including how to define a custom highlighted appearance for the node using CSS.\n *\n * Let's make the TreeViewPlugin show the node corresponding to whatever object {@link Entity} that we pick:\n *\n * ````javascript\n * viewer.cameraControl.on(\"picked\", function (e) {\n *     var objectId = e.entity.id;\n *     treeView.showNode(objectId);\n * });\n * ````\n *\n * This will de-highlight any node that was previously shown by this method.\n *\n * Note that this method only works if the picked {@link Entity} is an object that belongs to a model that's represented in the TreeViewPlugin.\n *\n * ## Customizing Appearance\n *\n * We can customize the appearance of our TreeViewPlugin by defining custom CSS for its HTML\n * elements. See our example's [source code](https://github.com/xeokit/xeokit-sdk/blob/master/examples/BIMOffline_XKT_Schependomlaan.html)\n * for an example of custom CSS rules.\n *\n * ## Model Hierarchies\n *\n * TreeViewPlugin has three hierarchies for organizing its nodes:\n *\n * * \"containment\" - organizes the tree nodes to indicate the containment hierarchy of the {@link MetaObject}s.\n * * \"types\" - groups nodes by their IFC types.\n * * \"storeys\" - groups nodes within their ````IfcBuildingStoreys````, and sub-groups them by their IFC types.\n *\n * <br>\n * The table below shows what the hierarchies look like:\n * <br>\n *\n * | 1. Containment Hierarchy | 2. Types Hierarchy | 3. Storeys Hierarchy |\n * |---|---|---|\n * | <img src=\"http://xeokit.io/img/docs/TreeViewPlugin/structureMode.png\"> | <img src=\"http://xeokit.io/img/docs/TreeViewPlugin/typesMode.png\"> | <img src=\"http://xeokit.io/img/docs/TreeViewPlugin/storeysMode.png\"> |\n * <br>\n *\n * Let's create a TreeViewPlugin that groups nodes by their building stories and IFC types:\n *\n * ````javascript\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"myTreeViewContainer\"),\n *      hierarchy: \"stories\"\n * });\n * ````\n *\n * ## Sorting Nodes\n *\n * TreeViewPlugin sorts its tree nodes by default. For a \"storeys\" hierarchy, it orders ````IfcBuildingStorey```` nodes\n * spatially, with the node for the highest story at the top, down to the lowest at the bottom.\n *\n * For all the hierarchy types (\"containment\", \"classes\" and \"storeys\"), TreeViewPlugin sorts the other node types\n * alphanumerically on their titles.\n *\n * If for some reason you need to prevent sorting, create your TreeViewPlugin with the option disabled, like so:\n *\n * ````javascript\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"myTreeViewContainer\"),\n *      hierarchy: \"stories\",\n *      sortNodes: false // <<------ Disable node sorting\n * });\n * ````\n *\n * Note that, for all hierarchy modes, node sorting is only done for each model at the time that it is added to the TreeViewPlugin, and will not\n * update dynamically if we later transform the {@link Entity}s corresponding to the nodes.\n *\n * ## Pruning empty nodes\n *\n * Sometimes a model contains subtrees of objects that don't have any geometry. These are models whose\n * {@link MetaModel} contains trees of {@link MetaObject}s that don't have any {@link Entity}s in the {@link Scene}.\n *\n * For these models, the tree view would contain nodes that don't do anything in the Scene when we interact with them,\n * which is undesirable.\n *\n * By default, TreeViewPlugin will not create nodes for those objects. However, we can override that behaviour if we want\n * to have nodes for those objects (perhaps for debugging the model):\n *\n * ````javascript\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"myTreeViewContainer\"),\n *      hierarchy: \"stories\",\n *      pruneEmptyNodes: false // <<------ Create nodes for object subtrees without geometry\n * });\n * ````\n *\n * ## Context Menu\n *\n * TreeViewPlugin fires a \"contextmenu\" event whenever we right-click on a tree node.\n *\n * The event contains:\n *\n * * ````event```` - the original [contextmenu](https://developer.mozilla.org/en-US/docs/Web/API/Element/contextmenu_event) [MouseEvent](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent)\n * * ````viewer```` - the {@link Viewer}\n * * ````treeViewPlugin```` - the TreeViewPlugin\n * * ````treeViewNode```` - the {@link TreeViewNode} representing the tree node\n *<br><br>\n *\n * Let's use {@link ContextMenu} to show a simple context menu for the node we clicked.\n *\n * [[Run an example](https://xeokit.github.io/xeokit-sdk/examples/#ContextMenu_Canvas_TreeViewPlugin_Custom)]\n *\n * ````javascript\n * import {ContextMenu} from \"../src/extras/ContextMenu/ContextMenu.js\";\n *\n * const treeViewContextMenu = new ContextMenu({\n *     items: [\n *         [\n *             [\n *                 {\n *                     title: \"Hide\",\n *                     doAction: function (context) {\n *                         context.treeViewPlugin.withNodeTree(context.treeViewNode, (treeViewNode) => {\n *                             if (treeViewNode.objectId) {\n *                                 const entity = context.viewer.scene.objects[treeViewNode.objectId];\n *                                 if (entity) {\n *                                     entity.visible = false;\n *                                 }\n *                             }\n *                         });\n *                     }\n *                 },\n *                 {\n *                     title: \"Hide all\",\n *                     doAction: function (context) {\n *                         context.viewer.scene.setObjectsVisible(context.viewer.scene.visibleObjectIds, false);\n *                     }\n *                 }\n *             ],\n *             [\n *                 {\n *                     title: \"Show\",\n *                     doAction: function (context) {\n *                         context.treeViewPlugin.withNodeTree(context.treeViewNode, (treeViewNode) => {\n *                             if (treeViewNode.objectId) {\n *                                 const entity = context.viewer.scene.objects[treeViewNode.objectId];\n *                                 if (entity) {\n *                                     entity.visible = true;\n *                                     entity.xrayed = false;\n *                                     entity.selected = false;\n *                                 }\n *                             }\n *                         });\n *                     }\n *                 },\n *                 {\n *                     title: \"Show all\",\n *                     doAction: function (context) {\n *                         const scene = context.viewer.scene;\n *                         scene.setObjectsVisible(scene.objectIds, true);\n *                         scene.setObjectsXRayed(scene.xrayedObjectIds, false);\n *                         scene.setObjectsSelected(scene.selectedObjectIds, false);\n *                     }\n *                 }\n *             ]\n *         ]\n *     ]\n * });\n *\n * treeView.on(\"contextmenu\", (e) => {\n *\n *     const event = e.event;                           // MouseEvent\n *     const viewer = e.viewer;                         // Viewer\n *     const treeViewPlugin = e.treeViewPlugin;         // TreeViewPlugin\n *     const treeViewNode = e.treeViewNode;             // TreeViewNode\n *\n *     treeViewContextMenu.show(e.event.pageX, e.event.pageY);\n *\n *     treeViewContextMenu.context = {\n *         viewer: e.viewer,\n *         treeViewPlugin: e.treeViewPlugin,\n *         treeViewNode: e.treeViewNode\n *     };\n * });\n * ````\n *\n * ## Clicking Node Titles\n *\n * TreeViewPlugin fires a \"nodeTitleClicked\" event whenever we left-click on a tree node.\n *\n * Like the \"contextmenu\" event, this event contains:\n *\n * * ````event```` - the original [click](https://developer.mozilla.org/en-US/docs/Web/API/Element/click_event) [MouseEvent](https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent)\n * * ````viewer```` - the {@link Viewer}\n * * ````treeViewPlugin```` - the TreeViewPlugin\n * * ````treeViewNode```` - the {@link TreeViewNode} representing the tree node\n *<br><br>\n *\n * Let's register a callback to isolate and fit-to-view the {@link Entity}(s) represented by the node. This callback is\n * going to X-ray all the other Entitys, fly the camera to fit the Entity(s) for the clicked node, then hide the other Entitys.\n *\n * [[Run an example](https://xeokit.github.io/xeokit-sdk/examples/#ContextMenu_Canvas_TreeViewPlugin_Custom)]\n *\n * ````javascript\n * treeView.on(\"nodeTitleClicked\", (e) => {\n *     const scene = viewer.scene;\n *     const objectIds = [];\n *     e.treeViewPlugin.withNodeTree(e.treeViewNode, (treeViewNode) => {\n *         if (treeViewNode.objectId) {\n *             objectIds.push(treeViewNode.objectId);\n *         }\n *     });\n *     scene.setObjectsXRayed(scene.objectIds, true);\n *     scene.setObjectsVisible(scene.objectIds, true);\n *     scene.setObjectsXRayed(objectIds, false);\n *     viewer.cameraFlight.flyTo({\n *         aabb: scene.getAABB(objectIds),\n *         duration: 0.5\n *     }, () => {\n *         setTimeout(function () {\n *             scene.setObjectsVisible(scene.xrayedObjectIds, false);\n *             scene.setObjectsXRayed(scene.xrayedObjectIds, false);\n *         }, 500);\n *     });\n * });\n * ````\n *\n * To make the cursor change to a pointer when we hover over the node titles, and also to make the titles change to blue, we'll also define this CSS for the ````<span>```` elements\n * that represent the titles of our TreeViewPlugin nodes:\n *\n * ````css\n * #treeViewContainer ul li span:hover {\n *      color: blue;\n *      cursor: pointer;\n * }\n * ````\n *\n * @class TreeViewPlugin\n */\nclass TreeViewPlugin extends Plugin {\n\n    /**\n     * @constructor\n     *\n     * @param {Viewer} viewer The Viewer.\n     * @param {*} cfg Plugin configuration.\n     * @param {HTMLElement} cfg.containerElement DOM element to contain the TreeViewPlugin.\n     * @param {Boolean} [cfg.autoAddModels=true] When ````true```` (default), will automatically add each model as it's created.

The XKTLoaderPlugin also creates an {@link Entity} for each object within the\n * model. Those Entities will have {@link Entity#isObject} set ````true```` and will be registered\n * by {@link Entity#id} in {@link Scene#objects}.\n *\n * ## Metadata\n *\n * XKTLoaderPlugin can also load an accompanying JSON metadata file with each model, which creates a {@link MetaModel} corresponding\n * to the model {@link Entity} and a {@link MetaObject} corresponding to each object {@link Entity}.\n *\n * Each {@link MetaObject} has a {@link MetaObject#type}, which indicates the classification of its corresponding {@link Entity}. When loading\n * metadata, we can also configure XKTLoaderPlugin with a custom lookup table of initial values to set on the properties of each type of {@link Entity}. By default, XKTLoaderPlugin\n * uses its own map of default colors and visibilities for IFC element types.\n *\n * ## Usage\n *\n * In the example below we'll load the Schependomlaan model from a [.XKT file](https://github.com/xeokit/xeokit-sdk/tree/master/examples/models/xkt/schependomlaan), along\n * with an accompanying JSON [IFC metadata file](https://github.com/xeokit/xeokit-sdk/tree/master/examples/metaModels/schependomlaan).\n *\n * This will create a bunch of {@link Entity}s that represents the model and its objects, along with a {@link MetaModel} and {@link MetaObject}s\n * that hold their metadata.\n *\n * Since this model contains IFC types, the XKTLoaderPlugin will set the initial appearance of each object {@link Entity} according to its IFC type in {@link XKTLoaderPlugin#objectDefaults}.\n *\n * Read more about this example in the user guide on [Viewing BIM Models Offline](https://github.com/xeokit/xeokit-sdk/wiki/Viewing-BIM-Models-Offline).\n *\n * * [[Run example](https://xeokit.github.io/xeokit-sdk/examples/#BIMOffline_XKT_metadata_Schependomlaan)]\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n *\n * //------------------------------------------------------------------------------------------------------------------\n * // 1.

The\n   code lengths are lens[0..codes-1].  Each length corresponds to the\n   symbols 0..codes-1.  The Huffman code is generated by first sorting the\n   symbols by length from short to long, and retaining the symbol order\n   for codes with equal lengths.  Then the code starts with all zero bits\n   for the first code of the shortest length, and the codes are integer\n   increments for the same length, and zeros are appended as the length\n   increases.  For the deflate format, these bits are stored backwards\n   from their more natural integer increment ordering, and so when the\n   decoding tables are built in the large loop below, the integer codes\n   are incremented backwards.\n\n   This routine assumes, but does not check, that all of the entries in\n   lens[] are in the range 0..MAXBITS.  The caller must assure this.\n   1..MAXBITS is interpreted as that code length.  zero means that that\n   symbol does not occur in this code.\n\n   The codes are sorted by computing a count of codes for each length,\n   creating from that a table of starting indices for each length in the\n   sorted table, and then entering the symbols in order in the sorted\n   table.  The sorted table is work[], with that space being provided by\n   the caller.\n\n   The length counts are used for other purposes as well, i.e. finding\n   the minimum and maximum length codes, determining if there are any\n   codes at all, checking for a valid set of lengths, and looking ahead\n   at length counts to determine sub-table sizes when building the\n   decoding tables.\n   */\n\n            /* accumulate lengths for codes (assumes lens[] all in 0..MAXBITS) */\n            for (len = 0; len <= MAXBITS; len++) {\n                count[len] = 0;\n            }\n            for (sym = 0; sym < codes; sym++) {\n                count[lens[lens_index + sym]]++;\n            }\n\n            /* bound code lengths, force root to be within code lengths */\n            root = bits;\n            for (max = MAXBITS; max >= 1; max--) {\n                if (count[max] !== 0) { break; }\n            }\n            if (root > max) {\n                root = max;\n            }\n            if (max === 0) {                     /* no symbols to code at all */\n                //table.op[opts.table_index] = 64;  //here.op = (var char)64;    /* invalid code marker */\n                //table.bits[opts.table_index] = 1;   //here.bits = (var char)1;\n                //table.val[opts.table_index++] = 0;   //here.val = (var short)0;\n                table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n\n                //table.op[opts.table_index] = 64;\n                //table.bits[opts.table_index] = 1;\n                //table.val[opts.table_index++] = 0;\n                table[table_index++] = (1 << 24) | (64 << 16) | 0;\n\n                opts.bits = 1;\n                return 0;     /* no symbols, but wait for decoding to report error */\n            }\n            for (min = 1; min < max; min++) {\n                if (count[min] !== 0) { break; }\n            }\n            if (root < min) {\n                root = min;\n            }\n\n            /* check for an over-subscribed or incomplete set of lengths */\n            left = 1;\n            for (len = 1; len <= MAXBITS; len++) {\n                left <<= 1;\n                left -= count[len];\n                if (left < 0) {\n                    return -1;\n                }        /* over-subscribed */\n            }\n            if (left > 0 && (type === CODES || max !== 1)) {\n                return -1;                      /* incomplete set */\n            }\n\n            /* generate offsets into symbol table for each length for sorting */\n            offs[1] = 0;\n            for (len = 1; len < MAXBITS; len++) {\n                offs[len + 1] = offs[len] + count[len];\n            }\n\n            /* sort symbols by length, by symbol order within each length */\n            for (sym = 0; sym < codes; sym++) {\n                if (lens[lens_index + sym] !== 0) {\n                    work[offs[lens[lens_index + sym]]++] = sym;\n                }\n            }\n\n            /*\n   Create and fill in decoding tables.

This is saved in low to check for when a\n   new sub-table should be started.  drop is zero when the root table is\n   being filled, and drop is root when sub-tables are being filled.\n\n   When a new sub-table is needed, it is necessary to look ahead in the\n   code lengths to determine what size sub-table is needed.

Internally, the XML3DLoaderPlugin uses the\n * [zip.js](https://gildas-lormeau.github.io/zip.js/) library to unzip them before loading. The zip.js library uses\n * [Web workers](https://www.w3.org/TR/workers/) for fast unzipping, so XML3DLoaderPlugin requires that we configure it\n * with a ````workerScriptsPath```` property specifying the directory where zip.js keeps its Web worker script. See\n * the example for how to do that.\n *\n * ## Usage\n *\n * In the example below, we'll use an XML3DLoaderPlugin to load a 3DXML model. When the model has loaded,\n * we'll use the {@link CameraFlightAnimation} to fly the {@link Camera} to look at boundary of the model. We'll\n * then get the model's {@link Entity} from the {@link Scene} and highlight the whole model.\n *\n * * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#loading_3DXML_Widget)]\n *\n * ````javascript\n * // Create a xeokit Viewer\n * const viewer = new Viewer({\n *      canvasId: \"myCanvas\"\n * });\n *\n * // Add an XML3DLoaderPlugin to the Viewer\n * var plugin = new XML3DLoaderPlugin(viewer, {\n *      id: \"XML3DLoader\",  // Default value\n *      workerScriptsPath : \"../../src/plugins/XML3DLoader/zipjs/\" // Path to zip.js workers dir\n * });\n *\n * // Load the 3DXML model\n * var model = plugin.load({ // Model is an Entity\n *     id: \"myModel\",\n *     src: \"./models/xml3d/3dpreview.3dxml\",\n *     scale: [0.1, 0.1, 0.1],\n *     rotate: [90, 0, 0],\n *     translate: [100,0,0],\n *     edges: true\n * });\n *\n * // When the model has loaded, fit it to view\n * model.on(\"loaded\", function() {\n *      viewer.cameraFlight.flyTo(model);\n * });\n *\n * // Update properties of the model via the entity\n * model.highlighted = true;\n *\n * // Find the model Entity by ID\n * model = viewer.scene.models[\"myModel\"];\n *\n * // Destroy the model\n * model.destroy();\n * ````\n * ## Loading MetaModels\n *\n * We have the option to load a {@link MetaModel} that contains a hierarchy of {@link MetaObject}s that classifes the objects within\n * our 3DXML model.\n *\n * This is useful for building a tree view to navigate the objects, using {@link TreeViewPlugin}.\n *\n * Let's load the model again, this time creating a MetaModel:\n *\n * ````javascript\n * var model = plugin.load({\n *     id: \"myModel\",\n *     src: \"./models/xml3d/3dpreview.3dxml\",\n *     scale: [0.1, 0.1, 0.1],\n *     rotate: [90, 0, 0],\n *     translate: [100,0,0],\n *     edges: true,\n *\n *     createMetaModel: true // <<-------- Create a MetaModel\n * });\n * ````\n *\n * The MetaModel can then be found on the {@link Viewer}'s {@link MetaScene}, using the model's ID:\n *\n * ````javascript\n * const metaModel = viewer.metaScene.metaModels[\"myModel\"];\n * ````\n *\n * Now we can use {@link TreeViewPlugin} to create a tree view to navigate our model's objects:\n *\n * ````javascript\n * import {TreeViewPlugin} from \"../src/plugins/TreeViewPlugin/TreeViewPlugin.js\";\n *\n * const treeView = new TreeViewPlugin(viewer, {\n *     containerElement: document.getElementById(\"myTreeViewContainer\")\n * });\n *\n * const treeView = new TreeViewPlugin(viewer, {\n *      containerElement: document.getElementById(\"treeViewContainer\"),\n *      autoExpandDepth: 3, // Initially expand tree three storeys deep\n *      hierarchy: \"containment\",\n *      autoAddModels: false\n * });\n *\n * model.on(\"loaded\", () => {\n *      treeView.addModel(model.id);\n * });\n * ````\n *\n * Note that only the TreeViewPlugin \"containment\" hierarchy makes sense for an XML3D model.

This will cause the {@link Camera}\n * to fly to that Entity. Our target then becomes the center of that Entity. If we are currently pivoting,\n * then our pivot position is then also set to the Entity center.\n *\n * Disable that behaviour by setting {@link CameraControl#doublePickFlyTo} ````false````.\n *\n * # First-Person Mode\n *\n * In first-person mode, ````CameraControl```` rotates the World about the {@link Camera} position.\n *\n * To enable first-person mode:\n *\n * ````javascript\n * cameraControl.navMode = \"firstPerson\";\n * ````\n *\n * Then rotate by:\n *\n * * left-dragging the mouse,\n * * tap-dragging the touch pad,\n * * pressing arrow keys, or ````Q```` and ````E```` on a QWERTY keyboard, or ````A```` and ````E```` on an AZERTY keyboard.\n * <br><br>\n *\n * Dolly forwards and backwards by:\n *\n * * spinning the mouse wheel,\n * * pinching on the touch pad, and\n * * pressing the ````+```` and ````-```` keys, or ````W```` and ````S```` on a QWERTY keyboard, or ````Z```` and ````S```` for AZERTY.\n * <br><br>\n *\n * Pan left, right, up and down by:\n *\n * * left-dragging or right-dragging the mouse, and\n * * tap-dragging the touch pad with SHIFT down.\n *\n * Pan forwards, backwards, left, right, up and down by pressing the ````WSADZX```` keys on a QWERTY keyboard,\n * or ````WSQDWX```` keys on an AZERTY keyboard.\n * <br><br>\n *\n * ## Following the Pointer in First-Person Mode\n *\n * When {@link CameraControl#followPointer} is ````true```` in first-person mode, the mouse or touch pointer will dynamically\n * indicate the target to which the {@link Camera} will dolly to and from. In first-person mode, however, the World will always rotate\n * about the {@link Camera} position.\n *\n * Lets ensure that we're in first-person mode, then enable the {@link Camera} to follow the pointer:\n *\n * ````javascript\n * cameraControl.navMode = \"firstPerson\";\n * cameraControl.followPointer = true;\n * ````\n *\n * When the pointer is over empty space, the target will remain the last object that the pointer was over.\n *\n * ## Constraining Vertical Position in First-Person Mode\n *\n * In first-person mode, we can lock the {@link Camera} to its current position on the vertical World axis, which is useful for walk-through navigation:\n *\n * ````javascript\n * cameraControl.constrainVertical = true;\n * ````\n *\n * ## Axis-Aligned Views in First-Person Mode\n *\n * In first-person mode we can use keys 1-6 to position the {@link Camera} to look at the center of\n * the {@link Scene} from along each of the six World-space axis. Pressing one of these keys will fly the {@link Camera} to the\n * corresponding axis-aligned view.\n *\n * ## View-Fitting Entitys in First-Person Mode\n *\n * As in orbit mode, when in first-person mode and {@link CameraControl#doublePickFlyTo} is ````true````, we can double-click\n * or double-tap an {@link Entity} (ie. \"double-picking\") to fit it in view. This will cause the {@link Camera} to fly to\n * that Entity.

Pressing one of these keys will fly the {@link Camera} to the\n * corresponding axis-aligned view.\n *\n * # CameraControl Events\n *\n * ````CameraControl```` fires events as we interact with {@link Entity}s using mouse or touch input.\n *\n * The following examples demonstrate how to subscribe to those events.\n *\n * The first example shows how to save a handle to a subscription, which we can later use to unsubscribe.\n *\n * ## \"hover\"\n *\n * Event fired when the pointer moves while hovering over an Entity.\n *\n * ````javascript\n * const onHover = cameraControl.on(\"hover\", (e) => {\n *      const entity = e.entity;

Our target then becomes the center of that Entity.\n *\n * Disable that behaviour by setting {@link CameraControl#doublePickFlyTo} ````false````.\n *\n * # Plan-View Mode\n *\n * In plan-view mode, ````CameraControl```` pans and rotates the {@link Camera}, without rotating it.\n *\n * To enable plan-view mode:\n *\n * ````javascript\n * cameraControl.navMode = \"planView\";\n * ````\n *\n * Dolly forwards and backwards by:\n *\n * * spinning the mouse wheel,\n * * pinching on the touch pad, and\n * * pressing the ````+```` and ````-```` keys.\n *\n * <br>\n * Pan left, right, up and down by:\n *\n * * left-dragging or right-dragging the mouse, and\n * * tap-dragging the touch pad with SHIFT down.\n *\n * Pan forwards, backwards, left, right, up and down by pressing the ````WSADZX```` keys on a QWERTY keyboard,\n * or ````WSQDWX```` keys on an AZERTY keyboard.\n * <br><br>\n *\n * ## Following the Pointer in Plan-View Mode\n *\n * When {@link CameraControl#followPointer} is ````true```` in plan-view mode, the mouse or touch pointer will dynamically\n * indicate the target to which the {@link Camera} will dolly to and from.  In plan-view mode, however, the {@link Camera} cannot rotate.\n *\n * Lets ensure that we're in plan-view mode, then enable the {@link Camera} to follow the pointer:\n *\n * ````javascript\n * cameraControl.navMode = \"planView\";\n * cameraControl.followPointer = true; // Default\n * ````\n *\n * When the pointer is over empty space, the target will remain the last object that the pointer was over.\n *\n * ## Axis-Aligned Views in Plan-View Mode\n *\n * As in orbit and first-person modes, in plan-view mode we can use keys 1-6 to position the {@link Camera} to look at the center of\n * the {@link Scene} from along each of the six World-space axis. Pressing one of these keys will fly the {@link Camera} to the\n * corresponding axis-aligned view.\n *\n * # CameraControl Events\n *\n * ````CameraControl```` fires events as we interact with {@link Entity}s using mouse or touch input.\n *\n * The following examples demonstrate how to subscribe to those events.\n *\n * The first example shows how to save a handle to a subscription, which we can later use to unsubscribe.\n *\n * ## \"hover\"\n *\n * Event fired when the pointer moves while hovering over an Entity.\n *\n * ````javascript\n * const onHover = cameraControl.on(\"hover\", (e) => {\n *      const entity = e.entity; // Entity\n *      const canvasPos = e.canvasPos; // 2D canvas position\n * });\n * ````\n *\n * To unsubscribe from the event:\n *\n * ````javascript\n * cameraControl.off(onHover);\n * ````\n *\n * ## \"hoverOff\"\n *\n * Event fired when the pointer moves while hovering over empty space.\n *\n * ````javascript\n * cameraControl.on(\"hoverOff\", (e) => {\n *      const canvasPos = e.canvasPos;\n * });\n * ````\n *\n * ## \"hoverEnter\"\n *\n * Event fired when the pointer moves onto an Entity.\n *\n * ````javascript\n * cameraControl.on(\"hoverEnter\", (e) => {\n *      const entity = e.entity;\n *      const canvasPos = e.canvasPos;\n * });\n * ````\n *\n * ## \"hoverOut\"\n *\n * Event fired when the pointer moves off an Entity.\n *\n * ````javascript\n * cameraControl.on(\"hoverOut\", (e) => {\n *      const entity = e.entity;\n *      const canvasPos = e.canvasPos;\n * });\n * ````\n *\n * ## \"picked\"\n *\n * Event fired when we left-click or tap on an Entity.\n *\n * ````javascript\n * cameraControl.on(\"picked\", (e) => {\n *      const entity = e.entity;\n *      const canvasPos = e.canvasPos;\n * });\n * ````\n *\n * ## \"pickedSurface\"\n *\n * Event fired when we left-click or tap on the surface of an Entity.\n *\n * ````javascript\n * cameraControl.on(\"picked\", (e) => {\n *      const entity = e.entity;\n *      const canvasPos = e.canvasPos;\n *      const worldPos = e.worldPos;

In the example below, we're creating a\n * scene comprised of {@link Scene}, {@link Material}, {@link ReadableGeometry} and\n * {@link Mesh} components, while letting xeokit generate its own ID for\n * the {@link ReadableGeometry}:\n *\n *````JavaScript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {Mesh} from \"../src/scene/mesh/Mesh.js\";\n * import {buildTorusGeometry} from \"../src/scene/geometry/builders/buildTorusGeometry.js\";\n * import {ReadableGeometry} from \"../src/scene/geometry/ReadableGeometry.js\";\n * import {PhongMaterial} from \"../src/scene/materials/PhongMaterial.js\";\n * import {Texture} from \"../src/scene/materials/Texture.js\";\n * import {Fresnel} from \"../src/scene/materials/Fresnel.js\";\n *\n * const viewer = new Viewer({\n *        canvasId: \"myCanvas\"\n *    });\n *\n * viewer.scene.camera.eye = [0, 0, 5];\n * viewer.scene.camera.look = [0, 0, 0];\n * viewer.scene.camera.up = [0, 1, 0];\n *\n * new Mesh(viewer.scene, {\n *      geometry: new ReadableGeometry(viewer.scene, buildTorusGeometry({\n *          center: [0, 0, 0],\n *          radius: 1.5,\n *          tube: 0.5,\n *          radialSegments: 32,\n *          tubeSegments: 24,\n *          arc: Math.PI * 2.0\n *      }),\n *      material: new PhongMaterial(viewer.scene, {\n *          id: \"myMaterial\",\n *          ambient: [0.9, 0.3, 0.9],\n *          shininess: 30,\n *          diffuseMap: new Texture(viewer.scene, {\n *              src: \"textures/diffuse/uvGrid2.jpg\"\n *          }),\n *          specularFresnel: new Fresnel(viewer.scene, {\n *              leftColor: [1.0, 1.0, 1.0],\n *              rightColor: [0.0, 0.0, 0.0],\n *              power: 4\n *          })\n *     })\n * });\n *````\n *\n * We can then find those components like this:\n *\n * ````javascript\n * // Find the Material\n * var material = viewer.scene.components[\"myMaterial\"];\n *\n * // Find all PhongMaterials in the Scene\n * var phongMaterials = viewer.scene.types[\"PhongMaterial\"];\n *\n * // Find our Material within the PhongMaterials\n * var materialAgain = phongMaterials[\"myMaterial\"];\n * ````\n *\n * ## Restriction on IDs\n *\n * Auto-generated IDs are of the form ````\"__0\"````, ````\"__1\"````, ````\"__2\"```` ... and so on.\n *\n * Scene maintains a map of these IDs, along with a counter that it increments each time it generates a new ID.\n *\n * If Scene has created the IDs listed above, and we then destroy the ````Component```` with ID ````\"__1\"````,\n * Scene will mark that ID as available, and will reuse it for the next default ID.\n *\n * Therefore, two restrictions your on IDs:\n *\n * * don't use IDs that begin with two underscores, and\n * * don't reuse auto-generated IDs of destroyed Components.\n *\n * ## Logging\n *\n * Components have methods to log ID-prefixed messages to the JavaScript console:\n *\n * ````javascript\n * material.log(\"Everything is fine, situation normal.\");\n * material.warn(\"Wait, whats that red light?\");\n * material.error(\"Aw, snap!\");\n * ````\n *\n * The logged messages will look like this in the console:\n *\n * ````text\n * [LOG]   myMaterial: Everything is fine, situation normal.\n * [WARN]  myMaterial: Wait, whats that red light..\n * [ERROR] myMaterial: Aw, snap!\n * ````\n *\n * ##

Ordinarily you'd be learning about ````PerformanceModel```` if you were writing your own model loader plugins.\n *\n * # Contents\n *\n * - [PerformanceModel](#performancemodel)\n * - [GPU-Resident Geometry](#gpu-resident-geometry)\n * - [Picking](#picking)\n * - [Example 1: Geometry Instancing](#example-1--geometry-instancing)\n * - [Finalizing a PerformanceModel](#finalizing-a-performancemodel)\n * - [Finding Entities](#finding-entities)\n * - [Example 2: Geometry Batching](#example-2--geometry-batching)\n * - [Classifying with Metadata](#classifying-with-metadata)\n * - [Querying Metadata](#querying-metadata)\n * - [Metadata Structure](#metadata-structure)\n * - [RTC Coordinates](#rtc-coordinates)\n *   - [Example 3: RTC Coordinates with Geometry Instancing](#example-2--rtc-coordinates-with-geometry-instancing)\n *   - [Example 4: RTC Coordinates with Geometry Batching](#example-2--rtc-coordinates-with-geometry-batching)\n *\n * ## PerformanceModel\n *\n * ````PerformanceModel```` uses two rendering techniques internally:\n *\n * 1. ***Geometry batching*** for unique geometries, combining those into a single WebGL geometry buffer, to render in one draw call, and\n * 2. ***geometry instancing*** for geometries that are shared by multiple meshes, rendering all instances of each shared geometry in one draw call.\n *\n * <br>\n * These techniques come with certain limitations:\n *\n * * Non-realistic rendering - while scene graphs can use xeokit's full set of material workflows, ````PerformanceModel```` uses simple Lambertian shading without textures.\n * * Static transforms - transforms within a ````PerformanceModel```` are static and cannot be dynamically translated, rotated and scaled the way {@link Node}s and {@link Mesh}es in scene graphs can.\n * * Immutable model representation - while scene graph {@link Node}s and\n * {@link Mesh}es can be dynamically plugged together, ````PerformanceModel```` is immutable,\n * since it packs its geometries into buffers and instanced arrays.\n *\n * ````PerformanceModel````'s API allows us to exploit batching and instancing, while exposing its elements as\n * abstract {@link Entity} types.\n *\n * {@link Entity} is the abstract base class for\n * the various xeokit components that represent models, objects, or anonymous visible elements. An Entity has a unique ID and can be\n * individually shown, hidden, selected, highlighted, ghosted, culled, picked and clipped, and has its own World-space boundary.\n *\n * * A ````PerformanceModel```` is an {@link Entity} that represents a model.\n * * A ````PerformanceModel```` represents each of its objects with an {@link Entity}.\n * * Each {@link Entity} has one or more meshes that define its shape.\n * * Each mesh has either its own unique geometry, or shares a geometry with other meshes.\n *\n * ## GPU-Resident Geometry\n *\n * For a low memory footprint, ````PerformanceModel```` stores its geometries in GPU memory only, compressed (quantized) as integers. Unfortunately, GPU-resident geometry is\n * not readable by JavaScript.\n *\n *\n * ## Example 1: Geometry Instancing\n *\n * In the example below, we'll use a ````PerformanceModel````\n * to build a simple table model using geometry instancing.\n *\n * We'll start by adding a reusable box-shaped geometry to our ````PerformanceModel````.\n *\n * Then, for each object in our model we'll add an {@link Entity}\n * that has a mesh that instances our box geometry, transforming and coloring the instance.\n *\n * [![](http://xeokit.io/img/docs/sceneGraph.png)](https://xeokit.github.io/xeokit-sdk/examples/#sceneRepresentation_PerformanceModel_instancing)\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#sceneRepresentation_PerformanceModel_instancing)]\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {PerformanceModel} from \"../src/viewer/scene/PerformanceModels/PerformanceModel.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\",\n *     transparent: true\n * });\n *\n * viewer.scene.camera.eye = [-21.80, 4.01, 6.56];\n * viewer.scene.camera.look = [0, -5.75, 0];\n * viewer.scene.camera.up = [0.37, 0.91, -0.11];\n *\n * // Build a PerformanceModel representing a table\n * // with four legs, using geometry instancing\n *\n * const performanceModel = new PerformanceModel(viewer.scene, {\n *     id: \"table\",\n *     isModel: true, // <--- Registers PerformanceModel in viewer.scene.models\n *     position: [0, 0, 0],\n *     scale: [1, 1, 1],\n *     rotation: [0, 0, 0]\n * });\n *\n * // Create a reusable geometry within the PerformanceModel\n * // We'll instance this geometry by five meshes\n *\n * performanceModel.createGeometry({\n *\n *     id: \"myBoxGeometry\",\n *\n *     // The primitive type -

We can also generate UI\n * components from the metadata, such as the tree view demonstrated in [this demo](https://xeokit.github.io/xeokit-sdk/examples/#BIMOffline_glTF_OTCConferenceCenter).\n *\n * This hierarchy allows us to express the hierarchical structure of a model while representing it in\n * various ways in the 3D scene (such as with ````PerformanceModel````, which\n * has a non-hierarchical scene representation).\n *\n * Note also that a {@link MetaObject} does not need to have a corresponding\n * {@link Entity} and vice-versa.\n *\n * # RTC Coordinates for 64-Bit Precision\n *\n * ````PerformanceModel```` can emulate 64-bit precision on GPUs using relative-to-center (RTC) coordinates.\n *\n * Consider a model that contains many small objects, but with such large spatial extents that 32 bits of GPU precision (accurate to ~7 digits) will not be sufficient to render all of the the objects without jittering.\n *\n * To prevent jittering, we could spatially subdivide the objects into \"tiles\". Each tile would have a center position, and the positions of the objects within the tile would be relative to that center (\"RTC coordinates\").\n *\n * While the center positions of the tiles would be 64-bit values, the object positions only need to be 32-bit.\n *\n * Internally, when rendering an object with RTC coordinates, xeokit first temporarily translates the camera viewing matrix by the object's tile's RTC center, on the CPU, using 64-bit math.\n *\n * Then xeokit loads the viewing matrix into its WebGL shaders, where math happens at 32-bit precision. Within the shaders, the matrix is effectively down-cast to 32-bit precision, and the object's 32-bit vertex positions are transformed by the matrix.\n *\n * We see no jittering, because with RTC a detectable loss of GPU accuracy only starts happening to objects as they become very distant from the camera viewpoint, at which point they are too small to be discernible anyway.\n *\n * ## RTC Coordinates with Geometry Instancing\n *\n * To use RTC with ````PerformanceModel```` geometry instancing, we specify an RTC center for the geometry. Then ````PerformanceModel```` assumes that all meshes that instance that geometry are within the same RTC coordinate system, ie. the meshes ````position```` and ````rotation```` properties are assumed to be relative to the geometry's ````rtcCenter````.\n *\n * For simplicity, our example's meshes all instance the same geometry. Therefore, our example model has only one RTC center.\n *\n * Note that the axis-aligned World-space boundary (AABB) of our model is ````[ -6, -9, -6, 1000000006, -2.5, 1000000006]````.\n *\n * [![](http://xeokit.io/img/docs/sceneGraph.png)](https://xeokit.github.io/xeokit-sdk/examples/#sceneRepresentation_PerformanceModel_batching)\n *\n * * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#sceneRepresentation_PerformanceModel_instancing_rtcCenter)]\n *\n * ````javascript\n * const rtcCenter = [100000000, 0, 100000000];\n *\n * performanceModel.createGeometry({\n *     id: \"box\",\n *     rtcCenter: rtcCenter, // This geometry's positions, and the transforms of all meshes that instance the geometry, are relative to the RTC center\n *     primitive: \"triangles\",\n *     positions: [ 1, 1, 1, -1, 1, 1, -1, -1, 1, 1, -1, 1 ... ],\n *     normals: [ 0, 0, 1, 0, 0, 1, 0, 0, 1, 0, 0, 1, ... ],\n *     indices: [ 0, 1, 2, 0, 2, 3, 4, 5, 6, 4, 6, 7, ... ],\n * });\n *\n * performanceModel.createMesh({\n *     id: \"leg1\",\n *     geometryId: \"box\",\n *     position: [-4, -6, -4],\n *     scale: [1, 3, 1],\n *     rotation: [0, 0, 0],\n *     color: [1, 0.3, 0.3]\n * });\n *\n * performanceModel.createEntity({\n *     meshIds: [\"leg1\"],\n *     isObject: true\n * });\n *\n * performanceModel.createMesh({\n *     id: \"leg2\",\n *     geometryId: \"box\",\n *     position: [4, -6, -4],\n *     scale: [1, 3, 1],\n *     rotation: [0, 0, 0],\n *     color: [0.3, 1.0, 0.3]\n * });\n *\n * performanceModel.createEntity({\n *     meshIds: [\"leg2\"],\n *     isObject: true\n * });\n *\n * performanceModel.createMesh({\n *     id: \"leg3\",\n *     geometryId: \"box\",\n *     position: [4, -6, 4],\n *     scale: [1, 3, 1],\n *     rotation: [0, 0, 0],\n *     color: [0.3, 0.3, 1.0]\n * });\n *\n * performanceModel.createEntity({\n *     meshIds: [\"leg3\"],\n *     isObject: true\n * });\n *\n * performanceModel.createMesh({\n *     id: \"leg4\",\n *     geometryId: \"box\",\n *     position: [-4, -6, 4],\n *     scale: [1, 3, 1],\n *     rotation: [0, 0, 0],\n *     color: [1.0, 1.0, 0.0]\n * });\n *\n * performanceModel.createEntity({\n *     meshIds: [\"leg4\"],\n *     isObject: true\n * });\n *\n * performanceModel.createMesh({\n *     id: \"top\",\n *     geometryId: \"box\",\n *     position: [0, -3, 0],\n *     scale: [6, 0.5, 6],\n *     rotation: [0, 0, 0],\n *     color: [1.0, 0.3, 1.0]\n * });\n *\n * performanceModel.createEntity({\n *     meshIds: [\"top\"],\n *     isObject: true\n * });\n * ````\n *\n * ## RTC Coordinates with Geometry Batching\n *\n * To use RTC with ````PerformanceModel```` geometry batching, we specify an RTC center (````rtcCenter````) for each mesh.

It darkens creases, cavities and surfaces\n * that are close to each other, which tend to be occluded from ambient light and appear darker.\n *\n * The animated GIF above shows the effect as we repeatedly enable and disable LogDepthBuf. When LogDepthBuf is enabled, we can see darkening\n * in regions such as the corners, and the crevices between stairs. This increases the amount of detail we can see when ambient\n * light is high, or when objects have uniform colors across their surfaces. Run the example to experiment with the various\n * LogDepthBuf configurations.\n *\n * xeokit's implementation of LogDepthBuf is based on the paper [Scalable Ambient Obscurance](https://research.nvidia.com/sites/default/files/pubs/2012-06_Scalable-Ambient-Obscurance/McGuire12LogDepthBuf.pdf).\n *\n * ## Caveats\n *\n * Currently, LogDepthBuf only works with perspective and orthographic projections. Therefore, to use LogDepthBuf, make sure {@link Camera#projection} is\n * either \"perspective\" or \"ortho\".\n *\n * {@link LogDepthBuf#scale} and {@link LogDepthBuf#intensity} must be tuned to the distance\n * between {@link Perspective#near} and {@link Perspective#far}, or the distance\n * between {@link Ortho#near} and {@link Ortho#far}, depending on which of those two projections the {@link Camera} is currently\n * using. Use the [live example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_LogDepthBuf_OTCConferenceCenter) to get a\n * feel for that.\n *\n * ## Usage\n *\n * In the example below, we'll start by logging a warning message to the console if LogDepthBuf is not supported by the\n * system.\n *\n *Then we'll enable and configure LogDepthBuf, position the camera, and configure the near and far perspective and orthographic\n * clipping planes. Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\",\n *     transparent: true\n * });\n *\n * const sao = viewer.scene.sao;\n *\n * if (!sao.supported) {\n *     sao.warn(\"LogDepthBuf is not supported on this system - ignoring LogDepthBuf configs\")\n * }\n *\n * sao.enabled = true; // Enable LogDepthBuf - only works if supported (see above)\n * sao.intensity = 0.20;\n * sao.bias = 0.5;\n * sao.scale = 1000.0;\n * sao.minResolution = 0.0;\n * sao.kernelRadius = 100;\n * sao.blendCutoff = 0.2;\n *\n * const camera = viewer.scene.camera;\n *\n * camera.eye = [3.69, 5.83, -23.98];\n * camera.look = [84.31, -29.88, -116.21];\n * camera.up = [0.18, 0.96, -0.21];\n *\n * camera.perspective.near = 0.1;\n * camera.perspective.far = 2000.0;\n *\n * camera.ortho.near = 0.1;\n * camera.ortho.far = 2000.0;\n * camera.projection = \"perspective\";\n *\n * const xktLoader = new XKTLoaderPlugin(viewer);\n *\n * const model = xktLoader.load({\n *     id: \"myModel\",\n *     src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n *     metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n *     edges: true\n * });\n * ````\n *\n * [[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_LogDepthBuf_OTCConferenceCenter)]\n *\n * ## Efficiency\n *\n * LogDepthBuf can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\n * it's recommended to use a low value for {@link LogDepthBuf#kernelRadius}.  A low radius will sample pixels that are close\n * to the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\n * objects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  LogDepthBuf for close objects\n * is more expensive than for objects far away, that occupy fewer pixels on the canvas.\n *\n * ## Selectively enabling LogDepthBuf for models\n *\n * When loading multiple models into a Scene, we sometimes only want LogDepthBuf on the models that are actually going to\n * show it, such as the architecture or structure, and not show LogDepthBuf on models that won't show it well, such as the\n * electrical wiring, or plumbing.\n *\n * To illustrate, lets load some of the models for the West Riverside Hospital. We'll enable LogDepthBuf on the structure model,\n * but disable it on the electrical and plumbing.\n *\n * This will only apply LogDepthBuf to those models if {@link LogDepthBuf#supported} and {@link LogDepthBuf#enabled} are both true.\n *\n * Note, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\n * process, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\n * pools of scratch memory.\n *\n * ````javascript\n * const structure = xktLoader.load({\n *      id: \"structure\",\n *      src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n *      metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n *      edges: true,\n *      saoEnabled: true\n *  });\n *\n *  structure.on(\"loaded\", () => {\n *\n *      const electrical = xktLoader.load({\n *          id: \"electrical\",\n *          src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n *          metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n *          edges: true\n *      });\n *\n *      electrical.on(\"loaded\", () => {\n *\n *          const plumbing = xktLoader.load({\n *              id: \"plumbing\",\n *              src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n *              metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n *                  edges: true\n *              });\n *          });\n *      });\n * });\n * ````\n *\n * ## Disabling LogDepthBuf while camera is moving\n *\n * For smoother interaction with large models on low-power hardware, we can disable LogDepthBuf while the {@link Camera} is moving:\n *\n * ````javascript\n * const timeoutDuration = 150; // Milliseconds\n * var timer = timeoutDuration;\n * var saoDisabled = false;\n *\n * const onCameraMatrix = scene.camera.on(\"matrix\", () => {\n *     timer = timeoutDuration;\n *     if (!saoDisabled) {\n *         scene.sao.enabled = false;\n *         saoDisabled = true;\n *     }\n * });\n *\n * const onSceneTick = scene.on(\"tick\", (tickEvent) => {\n *     if (!saoDisabled) {\n *         return;\n *     }\n *     timer -= tickEvent.deltaTime; // Milliseconds\n *     if (timer <= 0) {\n *         if (saoDisabled) {\n *             scene.sao.enabled = true;\n *             saoDisabled = false;\n *         }\n *     }\n * });\n * ````\n *\n *

This property can be dynamically updated. The Marker will fire a \"worldPos\" event whenever this property changes.\n * * {@link Marker#viewPos} holds the Marker's 3D View-space coordinates. This property is read-only, and is automatically updated from {@link Marker#worldPos} and the current {@link Camera} position. The Marker will fire a \"viewPos\" event whenever this property changes.\n * * {@link Marker#canvasPos} holds the Marker's 2D Canvas-space coordinates. This property is read-only, and is automatically updated from {@link Marker#canvasPos} and the current {@link Camera} position and projection. The Marker will fire a \"canvasPos\" event whenever this property changes.\n *\n * ## Visibility\n *\n * {@link Marker#visible} indicates if the Marker is currently visible. The Marker will fire a \"visible\" event whenever {@link Marker#visible} changes.\n *\n * This property will be ````false```` when:\n *\n * * {@link Marker#entity} is set to an {@link Entity}, and {@link Entity#visible} is ````false````,\n * * {@link Marker#occludable} is ````true```` and the Marker is occluded by some {@link Entity} in the 3D view, or\n * * {@link Marker#canvasPos} is outside the boundary of the {@link Canvas}.\n *\n * ## Usage\n *\n * In the example below, we'll create a Marker that's associated with a {@link Mesh} (which a type of {@link Entity}).\n *\n * We'll configure our Marker to\n * become invisible whenever it's occluded by any Entities in the canvas.\n *\n * We'll also demonstrate how to query the Marker's visibility status and position (in the World, View and\n * Canvas coordinate systems), and how to subscribe to change events on those properties.\n *\n * [[Run this example](http://xeokit.github.io/xeokit-sdk/examples/#Markers_SimpleExample)]\n *\n * ````javascript\n * import {Viewer} from \"../src/viewer/Viewer.js\";\n * import {GLTFLoaderPlugin} from \"../src/plugins/GLTFLoaderPlugin/GLTFLoaderPlugin.js\";\n * import {Marker} from \"../src/scene/markers/Marker.js\";\n *\n * const viewer = new Viewer({\n *     canvasId: \"myCanvas\"\n * });\n *\n * // Create the torus Mesh\n * // Recall that a Mesh is an Entity\n * new Mesh(viewer.scene, {\n *     geometry: new ReadableGeometry(viewer.scene, buildTorusGeometry({\n *         center: [0,0,0],\n *         radius: 1.0,\n *         tube: 0.5,\n *         radialSegments: 32,\n *         tubeSegments: 24,\n *         arc: Math.PI * 2.0\n *     }),\n *     material: new PhongMaterial(viewer.scene, {\n *         diffuseMap: new Texture(viewer.scene, {\n *             src: \"textures/diffuse/uvGrid2.jpg\"\n *         }),\n *         backfaces: true\n *     })\n * });\n *\n * // Create the Marker, associated with our Mesh Entity\n * const myMarker = new Marker({\n *      entity: entity,\n *      worldPos: [10,0,0],\n *      occludable: true\n * });\n *\n * // Get the Marker's current World, View and Canvas coordinates\n * const worldPos   = myMarker.worldPos;     // 3D World-space position\n * const viewPos    = myMarker.viewPos;      // 3D View-space position\n * const canvasPos  = myMarker.canvasPos;    // 2D Canvas-space position\n *\n * const visible = myMarker.visible;\n *\n * // Listen for change of the Marker's 3D World-space position\n * myMarker.on(\"worldPos\", function(worldPos) {\n *    //...\n * });\n *\n * // Listen for change of the Marker's 3D View-space position, which happens\n * // when either worldPos was updated or the Camera was moved\n * myMarker.on(\"viewPos\", function(viewPos) {\n *    //...\n * });\n *\n * // Listen for change of the Marker's 2D Canvas-space position, which happens\n * // when worldPos or viewPos was updated, or Camera's projection was updated\n * myMarker.on(\"canvasPos\", function(canvasPos) {\n *    //...\n * });\n *\n * // Listen for change of Marker visibility.

EmphasisMaterial configures\n * a wireframe representation of the {@link ReadableGeometry} for the selected emphasis mode, which will have inner edges (those edges between\n * adjacent co-planar triangles) removed for visual clarity. The ````edgeThreshold```` indicates that, for\n * this particular {@link ReadableGeometry}, an inner edge is one where the angle between the surface normals of adjacent triangles\n * is not greater than ````5```` degrees. That's set to ````2```` by default, but we can override it to tweak the effect\n * as needed for particular Geometries.\n *\n * Here's the example again, this time implicitly defaulting to the {@link Scene#edgeMaterial}.

It darkens creases, cavities and surfaces\n * that are close to each other, which tend to be occluded from ambient light and appear darker.\n *\n * The animated GIF above shows the effect as we repeatedly enable and disable SAO. When SAO is enabled, we can see darkening\n * in regions such as the corners, and the crevices between stairs.

It darkens creases, cavities and surfaces\nthat are close to each other, which tend to be occluded from ambient light and appear darker.\n\nThe animated GIF above shows the effect as we repeatedly enable and disable SAO. When SAO is enabled, we can see darkening\nin regions such as the corners, and the crevices between stairs. This increases the amount of detail we can see when ambient\nlight is high, or when objects have uniform colors across their surfaces. Run the example to experiment with the various\nSAO configurations.\n\nxeokit's implementation of SAO is based on the paper [Scalable Ambient Obscurance](https://research.nvidia.com/sites/default/files/pubs/2012-06_Scalable-Ambient-Obscurance/McGuire12SAO.pdf).\n\n## Caveats\n\nCurrently, SAO only works with perspective and orthographic projections. Therefore, to use SAO, make sure {@link Camera#projection} is\neither \"perspective\" or \"ortho\".\n\n{@link SAO#scale} and {@link SAO#intensity} must be tuned to the distance\nbetween {@link Perspective#near} and {@link Perspective#far}, or the distance\nbetween {@link Ortho#near} and {@link Ortho#far}, depending on which of those two projections the {@link Camera} is currently\nusing. Use the [live example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter) to get a\nfeel for that.\n\n## Usage\n\nIn the example below, we'll start by logging a warning message to the console if SAO is not supported by the\nsystem.\n\nThen we'll enable and configure SAO, position the camera, and configure the near and far perspective and orthographic\nclipping planes. Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n\n````javascript\nimport {Viewer} from \"../src/viewer/Viewer.js\";\nimport {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n\nconst viewer = new Viewer({\n    canvasId: \"myCanvas\",\n    transparent: true\n});\n\nconst sao = viewer.scene.sao;\n\nif (!sao.supported) {\n    sao.warn(\"SAO is not supported on this system - ignoring SAO configs\")\n}\n\nsao.enabled = true; // Enable SAO - only works if supported (see above)\nsao.intensity = 0.20;\nsao.bias = 0.5;\nsao.scale = 1.0;\nsao.minResolution = 0.0;\nsao.numSamples = 10;\nsao.kernelRadius = 100;\nsao.blendCutoff = 0.1;\n\nconst camera = viewer.scene.camera;\n\ncamera.eye = [3.69, 5.83, -23.98];\ncamera.look = [84.31, -29.88, -116.21];\ncamera.up = [0.18, 0.96, -0.21];\n\ncamera.perspective.near = 0.1;\ncamera.perspective.far = 2000.0;\n\ncamera.ortho.near = 0.1;\ncamera.ortho.far = 2000.0;\ncamera.projection = \"perspective\";\n\nconst xktLoader = new XKTLoaderPlugin(viewer);\n\nconst model = xktLoader.load({\n    id: \"myModel\",\n    src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n    metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n    edges: true\n});\n````\n\n[[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter)]\n\n## Efficiency\n\nSAO can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\nit's recommended to use a low value for {@link SAO#kernelRadius}.  A low radius will sample pixels that are close\nto the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\nobjects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  SAO for close objects\nis more expensive than for objects far away, that occupy fewer pixels on the canvas.\n\n## Selectively enabling SAO for models\n\nWhen loading multiple models into a Scene, we sometimes only want SAO on the models that are actually going to\nshow it, such as the architecture or structure, and not show SAO on models that won't show it well, such as the\nelectrical wiring, or plumbing.\n\nTo illustrate, lets load some of the models for the West Riverside Hospital. We'll enable SAO on the structure model,\nbut disable it on the electrical and plumbing.\n\nThis will only apply SAO to those models if {@link SAO#supported} and {@link SAO#enabled} are both true.\n\nNote, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\nprocess, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\npools of scratch memory.\n\n````javascript\nconst structure = xktLoader.load({\n     id: \"structure\",\n     src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n     metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n     edges: true,\n     saoEnabled: true\n });\n\n structure.on(\"loaded\", () => {\n\n     const electrical = xktLoader.load({\n         id: \"electrical\",\n         src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n         metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n         edges: true\n     });\n\n     electrical.on(\"loaded\", () => {\n\n         const plumbing = xktLoader.load({\n             id: \"plumbing\",\n             src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n             metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n                 edges: true\n             });\n         });\n     });\n});\n````\n\n## Disabling SAO while camera is moving\n\nFor smoother interaction with large models on low-power hardware, we can disable SAO while the {@link Camera} is moving:\n\n````javascript\nconst timeoutDuration = 150; // Milliseconds\nvar timer = timeoutDuration;\nvar saoDisabled = false;\n\nconst onCameraMatrix = scene.camera.on(\"matrix\", () => {\n    timer = timeoutDuration;\n    if (!saoDisabled) {\n        scene.sao.enabled = false;\n        saoDisabled = true;\n    }\n});\n\nconst onSceneTick = scene.on(\"tick\", (tickEvent) => {\n    if (!saoDisabled) {\n        return;\n    }\n    timer -= tickEvent.deltaTime; // Milliseconds\n    if (timer <= 0) {\n        if (saoDisabled) {\n            scene.sao.enabled = true;\n            saoDisabled = false;\n        }\n    }\n});\n````\n\n[[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#techniques_nonInteractiveQuality)]",

Finally, we'll use {@link XKTLoaderPlugin} to load the OTC Conference Center model.\n\n````javascript\nimport {Viewer} from \"../src/viewer/Viewer.js\";\nimport {XKTLoaderPlugin} from \"../src/plugins/XKTLoaderPlugin/XKTLoaderPlugin.js\";\n\nconst viewer = new Viewer({\n    canvasId: \"myCanvas\",\n    transparent: true\n});\n\nconst sao = viewer.scene.sao;\n\nif (!sao.supported) {\n    sao.warn(\"SAO is not supported on this system - ignoring SAO configs\")\n}\n\nsao.enabled = true; // Enable SAO - only works if supported (see above)\nsao.intensity = 0.15;\nsao.bias = 0.5;\nsao.scale = 1.0;\nsao.minResolution = 0.0;\nsao.numSamples = 10;\nsao.kernelRadius = 100;\nsao.blendCutoff = 0.1;\n\nconst camera = viewer.scene.camera;\n\ncamera.eye = [3.69, 5.83, -23.98];\ncamera.look = [84.31, -29.88, -116.21];\ncamera.up = [0.18, 0.96, -0.21];\n\ncamera.perspective.near = 0.1;\ncamera.perspective.far = 2000.0;\n\ncamera.ortho.near = 0.1;\ncamera.ortho.far = 2000.0;\ncamera.projection = \"perspective\";\n\nconst xktLoader = new XKTLoaderPlugin(viewer);\n\nconst model = xktLoader.load({\n    id: \"myModel\",\n    src: \"./models/xkt/OTCConferenceCenter/OTCConferenceCenter.xkt\",\n    metaModelSrc: \"./metaModels/OTCConferenceCenter/metaModel.json\",\n    edges: true\n});\n````\n\n[[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#postEeffects_SAO_OTCConferenceCenter)]\n\n## Efficiency\n\nSAO can incur some rendering overhead, especially on objects that are viewed close to the camera. For this reason,\nit's recommended to use a low value for {@link SAO#kernelRadius}.  A low radius will sample pixels that are close\nto the source pixel, which will allow the GPU to efficiently cache those pixels. When {@link Camera#projection} is \"perspective\",\nobjects near to the viewpoint will use larger radii than farther pixels. Therefore, computing  SAO for close objects\nis more expensive than for objects far away, that occupy fewer pixels on the canvas.\n\n## Selectively enabling SAO for models\n\nWhen loading multiple models into a Scene, we sometimes only want SAO on the models that are actually going to\nshow it, such as the architecture or structure, and not show SAO on models that won't show it well, such as the\nelectrical wiring, or plumbing.\n\nTo illustrate, lets load some of the models for the West Riverside Hospital. We'll enable SAO on the structure model,\nbut disable it on the electrical and plumbing.\n\nThis will only apply SAO to those models if {@link SAO#supported} and {@link SAO#enabled} are both true.\n\nNote, by the way, how we load the models in sequence. Since XKTLoaderPlugin uses scratch memory as part of its loading\nprocess, this allows the plugin to reuse that same memory across multiple loads, instead of having to create multiple\npools of scratch memory.\n\n````javascript\nconst structure = xktLoader.load({\n     id: \"structure\",\n     src: \"./models/xkt/WestRiverSideHospital/structure.xkt\",\n     metaModelSrc: \"./metaModels/WestRiverSideHospital/structure.json\",\n     edges: true,\n     saoEnabled: true\n });\n\n structure.on(\"loaded\", () => {\n\n     const electrical = xktLoader.load({\n         id: \"electrical\",\n         src: \"./models/xkt/WestRiverSideHospital/electrical.xkt\",\n         metaModelSrc: \"./metaModels/WestRiverSideHospital/electrical.json\",\n         edges: true\n     });\n\n     electrical.on(\"loaded\", () => {\n\n         const plumbing = xktLoader.load({\n             id: \"plumbing\",\n             src: \"./models/xkt/WestRiverSideHospital/plumbing.xkt\",\n             metaModelSrc: \"./metaModels/WestRiverSideHospital/plumbing.json\",\n                 edges: true\n             });\n         });\n     });\n});\n````\n\n## Disabling SAO while camera is moving\n\nFor smoother interaction with large models on low-power hardware, we can disable SAO while the {@link Camera} is moving:\n\n````javascript\nconst timeoutDuration = 150; // Milliseconds\nvar timer = timeoutDuration;\nvar saoDisabled = false;\n\nconst onCameraMatrix = scene.camera.on(\"matrix\", () => {\n    timer = timeoutDuration;\n    if (!saoDisabled) {\n        scene.sao.enabled = false;\n        saoDisabled = true;\n    }\n});\n\nconst onSceneTick = scene.on(\"tick\", (tickEvent) => {\n    if (!saoDisabled) {\n        return;\n    }\n    timer -= tickEvent.deltaTime; // Milliseconds\n    if (timer <= 0) {\n        if (saoDisabled) {\n            scene.sao.enabled = true;\n            saoDisabled = false;\n        }\n    }\n});\n````\n\n[[Run this example](https://xeokit.github.io/xeokit-sdk/examples/#techniques_nonInteractiveQuality)]",

// [xmin, ymin, zmin, xmax, ymax, zmax]\n * ````\n *\n * Subscribing to updates to the AABB, which occur whenever {@link Entity}s are transformed, their\n * {@link ReadableGeometry}s have been updated, or the {@link Camera} has moved:\n *\n * ````javascript\n * scene.on(\"boundary\", function() {\n *      var aabb = scene.aabb;\n * });\n * ````\n *\n * Getting the AABB of the {@link Entity}s with the given IDs:\n *\n * ````JavaScript\n * scene.getAABB();

This is useful when we want to render the\n * scene to multiple viewports, such as for stereo effects.\n *\n * In the example, below, we'll configure the Scene to render twice on each frame, each time to different viewport. We'll do this\n * with a callback that intercepts the Scene before each render and sets its {@link Viewport} to a\n * different portion of the canvas. By default, the Scene will clear the canvas only before the first render, allowing the\n * two views to be shown on the canvas at the same time.\n *\n * ````Javascript\n * var viewport = scene.viewport;\n *\n * // Configure Scene to render twice for each frame\n * scene.passes = 2; // Default is 1\n * scene.clearEachPass = false; // Default is false\n *\n * // Render to a separate viewport on each render\n *\n * var viewport = scene.viewport;\n * viewport.autoBoundary = false;\n *\n * scene.on(\"rendering\", function (e) {\n *      switch (e.pass) {\n *          case 0:\n *              viewport.boundary = [0, 0, 200, 200]; // xmin, ymin, width, height\n *              break;\n *\n *          case 1:\n *              viewport.boundary = [200, 0, 200, 200];\n *              break;\n *      }\n * });\n *\n * // We can also intercept the Scene after each render,\n * // (though we're not using this for anything here)\n * scene.on(\"rendered\", function (e) {\n *      switch (e.pass) {\n *          case 0:\n *              break;\n *\n *          case 1:\n *              break;\n *      }\n * });\n * ````\n *\n * ## Gamma correction\n *\n * Within its shaders, xeokit performs shading calculations in linear space.\n *\n * By default, the Scene expects color textures (eg. {@link PhongMaterial#diffuseMap},\n * {@link MetallicMaterial#baseColorMap} and {@link SpecularMaterial#diffuseMap}) to\n * be in pre-multipled gamma space, so will convert those to linear space before they are used in shaders. Other textures are\n * always expected to be in linear space.\n *\n * By default, the Scene will also gamma-correct its rendered output.\n *\n * You can configure the Scene to expect all those color textures to be linear space, so that it does not gamma-correct them:\n *\n * ````javascript\n * scene.gammaInput = false;\n * ````\n *\n * You would still need to gamma-correct the output, though, if it's going straight to the canvas, so normally we would\n * leave that enabled:\n *\n * ````javascript\n * scene.gammaOutput = true;\n * ````\n *\n * See {@link Texture} for more information on texture encoding and gamma.\n *\n * @class Scene\n */\nclass Scene extends Component {\n\n    /**\n     @private\n     */\n    get type() {\n        return \"Scene\";\n    }\n\n    /**\n     * @private\n     * @constructor\n     * @param {Viewer} viewer The Viewer this Scene belongs to.\n     * @param {Object} cfg Scene configuration.\n     * @param {String} [cfg.canvasId]  ID of an existing HTML canvas for the {@link Scene#canvas} - either this or canvasElement is mandatory.
