I see, that makes sense.
Hm, you mention that the scalar field is really easy to modify.
What kind of things do you think are possible for modifying this scalar field? Do you think it’s possible for us to define that we, for example, only want really simple face-loops around the arms and the legs? Or perhaps that one part of the generated mesh has higher mesh density? Or any of the other needs that have been mentioned in the initial PDF in this thread?
Perhaps, if we think this out carefully, the work you’ll do this GSoC can become a great base to create very good retopology tools upon!
