// .NAME vtkOpenGLGlyph3DMapper - vtkOpenGLGlyph3D on the GPU.
// .SECTION Description
// Do the same job than vtkGlyph3D but on the GPU. For this reason, it is
// a mapper not a vtkPolyDataAlgorithm. Also, some methods of vtkOpenGLGlyph3D
// don't make sense in vtkOpenGLGlyph3DMapper: GeneratePointIds, old-style
// SetSource, PointIdsName, IsPointVisible.
