[vtkusers] Re: Backface wireframe color

[Goodwin Lawlor]

It's possible but you'll have to modify vtkOpenGLProperty and
vtkOpenGLPolyDataMapper so that in wireframe mode vtk renders polygons (not
lines as it does now) and use glPolygonMode to change the representation.

Rendering will be slower because you're rendering polys rather than lines.

I've got some modified files for backface culling in wireframe mode. It used
to allow backface color of wireframes but I changed it to improve the
performance.

I could change it back and mail it to you if you build vtk from source.
