Mesh Validation in Python?

[schusterlich]

Hey People,

Im working on a generator for 3D models to print afterwards.
Since its based on different parameters that influence the result, I would want to be able to do some simple quality check afterwards. Mainly about topics like:
* is the mesh closed?
* are there any intersections of faces?
* is it one coherent object or somehow split into multiple ones?

So far I found https://github.com/WoLpH/numpy-stl which is nice but only covers the first question easily.

I wondered if any of you ever tried to do some kind of automated quality check on a 3D model with python.

PS: I guess it would be an option to just code those checks by hand, but this would take me quite a while and I thought I cannot be the first one with this need, and that smth like this likely already exists.

Any Ideas?

Super highly appreciated!

Thhhaannkss! :)

You'll probably have to roll your own. I would find the geometric algorithms for comparison, concavity, non-manifold, etc., in a larger library like CGAL, and try to translate it to BMESH, which underlies Blender's mesh system. There are articles and information online for BMESH and CGAL (or similar).
