Yes.

: Then you have to do a coordinate transformation
: so that your dents appear in the right place with
: the right orientation and scaling.

Ok, I will try.

: In the example i used a kind of 3d-gaussian-bell-
: falloff-function and added four differently placed
: copies of it to the rest of the isofunction.
: If you have a more specific shape in mind, tell me.
