[vtkusers] problem with vtkTriangleFilter/vtkPolygon

[Chen, Elvis]

Greetings,

I'm trying to follow the ClipCow.tcl(
http://public.kitware.com/cgi-bin/cvsweb.cgi/~checkout~/VTK/Examples/VisualizationAlgorithms/Tcl/ClipCow.tcl)
example to cut through a mesh and fill the cut-plane
with a flat polygon.  With the mesh I have, I got an
error of:


Warning: In
/cis/volume/people/chene/local/VTK4/VTK/Common/vtkPolygon.cxx,
line 592
vtkPolygon (0x439e10): Degenerate polygon encountered
during triangulation

and there is a "hole" in the cut plane that is
supposed to be filled-up.  I'm using VTK4 (official
release) with Python 2.2 on Solaris (SunOS 5.8).

is there a workaround on this?

thx very much,
