[vtkusers] top/bottom cell sides with different color

[Alexandre DARRAU]

Dear all,

I would have a question regarding VTK.
I have an unstructured grid where i am trying to plot a temperature
distribution on. I manage to get one color per cell suing lookup table but i
would like to color the top of one cell in blue and the bottom in red, do
you know if it is possible using VTK ? Can you explain me how to deal with
it ?

Thank you in advance for your answer

Alexandre
