[vtkusers] How to set colors for contour edges?

[Vladimir Dudnik]

Hello VTK users,

I'd like to set different colors for some contour edges. Let's consider a
closed rectangular contour, represented by vtkPolyData object.

Could you please provide an advice of what is the right way to set for
example red color for the contour right edge and green color for the left
edge?

I've attached a simple example of how contour rendering is currently done in
my program

vtk_polyline_colors.cxx

Thanks,
  Vladimir
