[vtkusers] Collision Detection in VTK

[Marco Petrone]

Here in CINECA we wrapped the VCollide library (which menages collision detection between
surfaces of triangles) into a VTK filter: it takes as input many polydatas (preprocessed with a
triangle filter) and produces in output either a the same polydatas with scalars set in the
colliding triangles or simply the list of colliding inputs and triangles.  It was working under
VTK 3.2/3.3 and now is being tested under 4.0. The biggest problem is I'm not sure the VCollide
can be freely redistributed...
This class is probably going to be part of the Multimod project (www.ior.it/multimod), if
possible I'll make everything public available on our web site: the other author, Paolo
Quadrani, already agreed about it, but I must listen to the project manager.
