I made a completely new solidify tool and want to make it into a C modifier now. It performs ok with python but for bigger meshes it just takes to long (it has basically O(N) time complexity so not that bad)
The goal of the new (as I call it for now) Manifold Solidify is to give meshes a manifold skin no matter how messy the vertex normals and topology are. I even included some experimental intersection fixing for beveled edges and closing holes. I uploaded the addon to github so you can try it.
I would like to know if a modifier version of that tool could make it into an official blender release (maybe even 2.81 if everything goes smooth). I would like to start programming it and would like to know prior if I’m wasting my time.
