Feature request for Mesh class: Merge adjacent faces that are coplanar; afterwards, remove unreferenced vertices

[caniko]

Is your feature request related to a problem? Please describe. I have a mesh where there are many coplanar faces that are adjacent, and I need them removed from my mesh.

Describe the solution you'd like A function that accepts vertices, faces and angle tolerance, and returns a new set of vertices and faces. The changes to the mesh should be printed out.

Describe alternatives you've considered The solution is already implemented in Blender; however, running Blender inside a script is highly unstable. How to replicate in Blender: Decimate modifier select "Planar" then apply.

Link to the source from Blender.

I submitted a copy of the same issue to Open3D.

Is this function present in the C++ version?

This sounds like a cool feature request for libigl, which if merged could be result in a python binding here. Note, igl has extremely limited support for general polygon meshes, so once this mesh is built there will not be a lot more that igl could do with it.

I'm closing this issue, but feel free to make the feature request at https://github.com/libigl/libigl/issues
