[vtkusers] ZBuffer fighting pb

[John Platt]

I think you will find that these functions only work for lines (in VTK
4.2 at least).

Subject: [vtkusers] ZBuffer fighting pb


Hello all,

I have a rendering problem with coincident geometry due to zbuffer
fighting. I
tried using the setResolveCoincidentTopologyToShiftZBuffer function with
different shift value but it does not help (default shift is .01 and
changing it
from .01 to .99 does not change anything, setting it to 1 result in a
wrong
zbuffer content). I then tried the other approach using a polygon offset
(setResolveCoincidentTopologyToPolygonOffset) without success. My test
is very
simple, I modified the 2 cones examples so that the base of one
overlapps with
the base of the second one. As soon as there is an interaction I can see
the pb.
I am using VTK 5.0.1. Can anyone help ?
Thanks in advance.

-Jerome
