[vtkusers] Re: Does EdgeVisibilityOn do anything?

[Goodwin Lawlor]

At the moment its just a property that is exported by vtkOOGLExporter

To get "EdgeVisibility" in VTK add two vtkActors (one surface, one
wireframe) to a vtkAssembly. You'll need to fiddle with coincident topology
in the mapper to get the rendering correct.

If you want to export the rendering as PDF of PS you'll need to backface
cull the wireframe (search the bug tracker for a patch to do this)
