You would need something like a proximity pattern/evaluator, and to
know if the normal at each vertex is toward inside or outside. For
proximity at 50%, you do not move. For other values, you move along
the normal... excepted that there is more than one normal per vertex,
so you need to average them all somehow (weight might not be trivial,
hoping they are all on the same side).
For proximity giving a low density, you move "inward" (erosion).
For proximity giving a high density, you move "outward" (filling hole)
The problem that remains: getting the initial mesh that satisfies the
