[vtkusers] Clipping PolyData with PolyData

[David Pont]

Hi Chris,
  I made a class to do this some time ago (vtkImplicitPolyData) and have 
sent it to a few people asking this kind of question on the list. Feedback 
has been almost nil (I got one positive report back), which may be good or 
bad news. I think it will work OK for what you want to do, at worst it may 
give you some ideas. I can send you the C++ code if you like.

   regards
     Dave Pont
