Thanks, it works perfectly when<br>
vtkMapper::SetResolveCoincidentTopologyToPolygonOffset is called. Do<br>
you have an idea of what kind of performance hit is involved with<br>
this?<br>

Also, I was unaware of the EdgeVisibility on the property. Is there a<br>
way to get it to render just the edges, and not the cells (like set<br>
SurfaceVisibilityOff())?<br>
