surface/plane intersections

[Daphne Yu]

Hi vtk users, 

I was wondering if anyone has some good ideas as to a fast
way to find the intersection between a triangular surface and a plane
which goes through it?  It'd be also nice if there's a way
to do this such that local updates will be possible (rather
than searching through the whole surface again every time
the surface has changed.)

I was thinking of using a method like deviding the space into
cubes and search the local triangles' intersection with the plane.
What would be a good way to do this using the vtk library?

thanks in advance!
