<P>Hi krs,</P>
<P> I have a class that will let treat polydata (your isosurface?) as an implicit function, so you could use it to clip or cut. You could also use ImplicitBoolean to get union, intersection, difference etc between the two surfaces. If you are interested I can send you the C++ source.</P>
<P> regards</P>

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