Remarks
Call VertexFunc/EdgeFunc/TriangleFunc for the mesh vertices/edges/triangles identified by MeshSelection, where MeshSelection has polygroup topology referring to the provided GroupTopology Since a MeshSelection only stores vertices, edges, or triangles, but not combined, only one of these functions will be invoked during a call to this function. This function is useful to collect up geometry that needs to be rendered for a given MeshSelection
Parameters

| ApplyTransform | if non-null, transform is applied to the 3D geometry |
