I have written a set of classes to do this:
http://www.midasjournal.org/browse/publication/708
http://www.midasjournal.org/browse/publication/713

It is a pretty naive implementation, but it's worth a shot.

I strongly urge that these classes be added to VTK so we don't have to point
people to CGAL to do this type of thing.

Thanks,
