Well, with a torus, you could modify the function so that it takes the same
value at any point moving away from the surface of the *torus* instead of a
sphere. That would be more difficult than the sphere example I gave, and, of
course, get even harder when working with more complex functions. Usually,
if I have a shape that complex, I just multiply the noise function by a
small enough value that no overhangs or floating peices appear. The downside
is that you can't have huge bumps. I'm not sure if there's an easy solution
to that problem.
