Different colors for different parts of the glyph when using the vtkGlyph3DMapper

Thanks, this saves me a lot of time. Using separate mappers sounds like a good idea, although it may make picking more complicated but I guess I will have to have a try. Another question is can I assign different colors for the front and back side of the glyph? I need a way to differentiate the front and back but for now they looks the same even when I set the normals.
