-**iTowns** supports **WebGL 2.0** and is enabled by default.
-If you want instance instance with **WebGL 1.0** use option  **`renderer: { isWebGL2: false }`** to instance the viewer.

-### Example to instance viewer in WebGL 2.0.
-```js
-// for GlobeView
-const gView = new GlobeView(viewerDiv, placement);
-
-// for PlanarView
-const pView = new PlanarView(viewerDiv, extent);
-
-// for View
-const view = new View(crs, viewerDiv);
-
-// is version webgl 2.0 after instance?
-const isWebGL2 = view.mainLoop.gfxEngine.renderer.capabilities.isWebGL2; // true
-```
