I think it's great you are working with them on this. Since I have the way
to draw arbitrary lines on an isosurface in JVXL, I wonder if it would be
possible to do that (or some contouring) after the fact with isosurface --
sort of a combination of draw and isosurface.

If nature does not answer first what we want,
it is better to take what answer we get.
