[vtkusers] comparing polydata objects..

[K.R.Subramanian]

I am interesting in calculating the volume intercepted by an isosurface with each cell
it intersects in a grid. In other words, the isosurface is like an implicit function
(cutter).
What is an efficient way to do this?  My bigger problem is to compare two different
isosurfaces in terms of these  fractional volumes compueted at each of these grid cells.

Thanks.
