[vtkusers] directly specifying RGB values for polydata?

[Melissa Suter]

I know this question has been asked before, but I haven't been able to 
find any answers.  I have 3D polydata that I want to add color to.  I 
don't want to do this by indexing or by texture maping, but instead want 
to be able to directly specify point RGB values.  Is this possible in vtk?

Any help will be greatly appreciated.  Thanks in advance,
Melissa
