[vtkusers] How to map RGB color from vector data to points?

[Immo Trinks]

Hi,

I have a polydata set with xyz points and RGB vectors assigned to the points 
(see example below).
I use vtkPointSource and vtkGlyph3D to display the points as pixels.
How can I color the pixels using the vector RGB data?
Thank you very much for any help!
