If you'd like to contribute, here is an [up to date list of potential enhancements](https://github.com/mikedh/trimesh/issues/1557) although things not on that list are also welcome. Here's a quick [development and contributing guide.](https://trimesh.org/contributing.html)\n\n\n##...
Fix triangle winding and normals to be consistent Convex hulls of meshes Compute a rotation/translation/tessellation invariant identifier for meshes Determine duplicate meshes from identifier Determine if a mesh is watertight, convex, etc. Repair single triangle and single quad holes Uniformly sample the...
Support for per-vertex normals in OBJ files More support for pointclouds, including normal computation based on (accelerated) k-nearest-neighbors Stricter use of std namespace. This may require adding using declarations to client code for classes and functions that used to be injected into the ...
