Hi Arko,
Maybe I'm not quite getting what you mean, but the intersection of the
two spheres in volume space would simply be computed as
intersection=sphere1 and sphere2
provided that you've got binary volumes for the two objects.
Re surfaces, you might want to have a look at the newsgroup archives. If
you google surface intersection idlgrpolygon, you'll find an answer to a
similar problem.
Cheers,
Jo
