It's best understood by using it. Figuring out what bounded_by does, what
threshold changes and so on, can be learned through simple experimentation.

I guess the explanation of it would be 'math that forms a surface.' There
are points involved, but instead of say, x making a point at a certain
place, it makes a plane instead. Bill, I don't think I understand your
question fully. Any theory I have come up with regarding the isosurface I
learned through using it.

If you make an isosurface sphere, it is a sphere bounded by the bounded_by
object. If you make a y plane that has a sin(x) function on it, it is just
that, still bounded by an object. All isosurfaces must be bounded_by
something. If they weren't, they might take forever to render.
