Allows for vertices to be re-used across multiple triangles; this is called using "indexed triangles," and works much the same as it does in [page:Geometry]: each triangle is associated with the index of three vertices. This attribute therefore stores the index of each vertex for each triangular face.

If this attribute is not set, the [page:WebGLRenderer renderer] assumes that each three contiguous positions represent a single triangle.
