[vtkusers] How do I limit the drawing volume or clip the view ?

[David.Pont at ForestResearch.co.nz]

OK Paul,
  I will foward you the code off the list. There is no way to do this in
standard vtk. I have given my class to several people over time, but never
hear back if it works or not. If I was confident it was useful I would
happily contribute it to vtk. But I am hesitant because it is a 'bit of a
hack', and I understand how a 'correct' implementation should be done, but
have no time to work on that...
So please let me know how it works for you

Thanks, yes I'm a C++er

The upper and lower surfaces are seperate but each well is seperate too.
I'll look into vtkAppendPolyData which I haven't used before. I'd still
like
to see your code.

Hopefully someones can still come up with a "stabdard vtk" way of doinf
this
