[vtkusers] Weigted average of dataset attributes?

[Chris Want]

I have two vtkStructuredPoints objects
that are defined on the same data domain.
I would like to take a weighted average of
the scalars defined at each point, and
have that as the scalars for a third
vtkStructuredPoints object. This isn't too
hard to program myself, but I thought I'd
check to see if there was some vtk class
that did this automagically first.

Is there a class that will do this?

Cheers,
