Do you know SketchRetopo from Prof. Kenshi Takayama

I always dreamt about having this tool (which I collaborated to create is some of its ideas) implemented in Blender. This is the missing step between auto retopo and manual retopo: https://igl.ethz.ch/projects/sketch-retopo/ (Siggraph 2013)
There is also another paper based on that. It would be fantastic if you could somehow implement it in PolyQuilt

Thank you so much for this amazing add-on you share with us!

I've played around with that software too, it's quite promising. It's surprising that no one has made use of it yet.
