[vtkusers] how to visualize the inside of a polydata?

[Sylvain Jaume]

Hello VTK users,

I've got a colored surface polydata. I'd like to see the inside, so I clip
the polydata (with texture clipping). Since any vertex has the same
color from inside or outside, I cannot clearly distiguish the inside
surface from the outside surface.

Anybody knows a 'VTK trick' to visualize the inside surface?
Is it possible to set a property (color, texture,...) to the
inside surface different than the outside surface's property?

Thanks for your help!
