Oh.  I *think* I know what you're saying now.  Inclusion of a deformation
such as what happens when unsliced bread is cut into, pressing the surface
down as the knife goes in.
That requires a inside curve, the kind a cylinder can have if cut open along
its length, which can then be used to CSG difference from something else.

There must be a way to apply a cut into a isosurface like that, I just don't
know how right now.  I'd guess a subtraction of one shape from another could
do it.

Heck, now that I think about it, you partly answered yourself there by
mentioning "blobby".  Using a blob with negative strength and thinly scaled
component you could move it through the positive strength component(s) and
get just such an effect.  That is, if I understood the idea this time.
