[vtkusers] creating polygons from polylines and making holes in polygons (isolines related)

[Malcolm Drummond]

Hi Sebastien

One way is to use vtkGLUTesselatorTriangleFilter (by Tom Cintriniti - it's
in the contrib directory). Here's a tcl script and data file that shows
simple use (works under 3.2, should be OK under 4.x). You'll have to link
with the GLU library.

Hope this helps
Malcolm
