Version 8.0.0 beta 8

IECore

• Clang compatibility

IECoreGL

• Clang compatibility

Version 8.0.0 beta 7

IECore

• Added TransferSmoothSkinningWeightsOp
• Added GIL release for DisplayDriver imageData and imageClose binding

IECoreMaya

• Added ToMayaCurveConverter

IECoreHoudini

• Houdini 13 Compatibility (requires H13.0.267 to pass tests)
• Fixed HoudiniScene custom attribute bug when two callbacks define the same attribute
• Fixed exception when reading HoudiniScene custom attributes that didn't exist in the underlying scene
• Using handles instead of strings when validating the DetailSplitter

Version 8.0.0 beta 6

IECore

• LinkedScene( SceneInterfacePtr ) supports writable scenes
• Fixed SceneCache from IndexedIO bug
• Fixed linking issues with IECore::CamelCase

IECoreHoudini

• SceneCache SOP transforms all Point, Normal, and Vector primitive variables (previously it only transformed P and N)
• Preventing double cooking in HoudiniScene::scene( path )

Version 8.0.0 beta 5

IECore

• Improved error reporting in LinkedScene - the main filename is now available in error messages.
• Made RunTimeTyped baseTypeIds() and derivedTypeIds() methods thread safe.

IECoreGL

• Added IECoreGL::Selector::push/popIDShader() methods. These replace the now deprecated loadIDShader() method.
• Fixed crashes when selecting curves.

IECoreHoudini

• Added SceneCache Transform SOP. This node applies transformations from a SceneCache file directly on the points and primitives at the SOP level.
• FromHoudiniPolygon converter now automatically removes normal primvars when extracting a subdivision mesh.

IECoreNuke

• Added DeepImageReader - this allows any deep image type supported by Cortex to be read in Nuke.

Version 8.0.0 beta 4

IECore

• Optimised polygonNormal and polygonWinding in PolygonAlgo.h.
• Added face normals mode to MeshNormalsOp.

IECoreGL

• Fixed shading of polygon meshes with no "N" primitive variable (#118).

IECoreArnold

• Added support for Arnold parameters of type AI_TYPE_BYTE.
• Added compatibility with Arnold 4.1.
• Fixed hangs in procedurals.

Version 8.0.0 beta 3

IECore

• Fixed compile issue on Ubuntu

IECoreHoudini

• Improving performance of SceneCache SOP. This brings the animated performance back inline with 8.0.0-b1, while maintaining (if not improving) the on-load performance from 8.0.0-b2.
• Guaranteed SceneCache SOP shape/point order by sorting children by name before loading.
• Preventing crash in SceneCache ROP when cooking inside an invisible OBJ subnet.

Version 8.0.0 beta 2

IECore

• WarpOp has a new BoundMode parameter, options are Clamp (previous behaviour) or SetToBlack.
• ImageDiffOp has a new option to offset display windows of the same size to be aligned before comparison.
• Added support to the LensDistortOp for images with offset display window.
• Fixed LensDistortOp bug with non-symmetric distortions.

IECoreHoudini

• Added BoundingBox and PointCloud GeometryType options to SceneCache nodes
• Added AttributeCopy parm to SceneCache SOP. This is used to duplicate attributes before loading to Houdini.
• Exposed SceneCache OBJ parameters to override the transform values coming from disk (Transform tab)
• Moved SceneCache OBJ Push button along with all geometry loading parms to the new Options tab
• Improved performance of SceneCache SOP (Up to 5x faster on a 1500 shapes, 3 million polys asset)

Version 8.0.0 beta 1

IECore

• SceneInterface tags now support upstream/local/downstream tags (using a bit mask filter to query)
• Various fixes for OSX builds

IECoreHoudini

• Fixed multiple transform bug in HoudiniScene

Version 8.0.0 alpha 23

IECore

• Added new logos!

IECoreGL

• Added IECoreGL::glslVersion() function and python binding
• Added IECoreGL::FrameBuffer::frameBuffer() method
• OpenGL 2.1 compatibility fixes

IECoreHoudini

• Added bindings for SceneCacheNode which give access to the SceneInterface directly (or None if invalid)
• HoudiniScene provides python access to registering custom attribute and tag readers
• HoudiniScene now provides access to the world space transformation matrix of the held OBJ node
• Fixing crashes in HoudiniScene when pointing to broken SOPs
• Fixing crashes in SceneCacheWriter when given null attribute data
• Replaced some (but not all) of the misc cow logos with the new Cortex mini-logo

Version 8.0.0 alpha 22

IECoreHoudini

• ParameterisedHolder SOPs have a nameFilter parm (w/ disable toggle)
  • These are used to pre-filter each input geometry (or not if toggled off)
• ProceduralHolder outputs a single CortexObject holding its procedural
• OpHolder operates several times per cook, once for each named input shape
  • Shapes matching the filter are operated on, and returned as CortexObjects, maintaining their name
  • Shapes not matching are passed through unchanged, whether they were normal geo or CortexObjects
  • It can be forced to operate only once by disabling the nameFilter or by passing a single named shape
• CortexConverter SOP now operates in both directions (converting between CortexObjects and native geo)
  • It also has a nameFilter, with similar pass-through behaviour as the OpHolder
• Changed interface for HoudiniScene custom attribute callbacks
  • SceneCache OBJs pass attributes through to HoudiniScene (and therefor SceneCache ROP)
• Added IECoreHoudini.makeMainGLContextCurrent() which is needed for sharing the GL Context with other applications (like Gaffer)
• Fixed bug in HoudiniScene which was creating phony children when FlatGeometry names were similar, but not exact
• Fixed bug in SceneCache SOP when loading Groups or CoordinateSystems without a transform
• Preventing segmentation faults when reading a corrupt SceneCache file

IECoreGL

• Fixed GLSL shaders to work with GLSL version 120 (OpenGL 2.1)
