I’m making some progress on this.
I was just making some changes in Kangaroo’s Solid point collision in this thread, and after the changes I made for that, it seems to be working better for shrink wrapping.
Here’s a test -
from left to right -
input scanned mesh,
manually drawn skeleton,
fattened and subdivided,
shrink wrapped onto scan mesh to give a coarse quad layout (as described here)
This workflow still needs some improvement to be really reliable, but potentially could become a command.
