[vtkusers] boolean operations

[Bryn Lloyd]

Michele,

An alternative to using the Boolean package would be to use GTS (GNU 
triangulated surface library):
http://gts.sourceforge.net/

It is good at doing boolean operations, using (I think) exact arithmetic 
operations. I have found it is quite robust.

Here is an explanation how to create a gts surface from a vtk polydata 
(surface):

Cheers
