       | Anyway, don't forget to use uv (https://docs.astral.sh/uv/)
       | because it's nice. Have fun.

       | Awesome that this includes a mesh repair project:
       | https://pymeshfix.pyvista.org/
       | 
       | Some slicers only offer Mesh Repair on Windows because they
       | depend on the Printing3DModel API [1]. MeshLab is OSS and
       | powerful, but hard to use [2]

           | I've used PyVista extensively for making figures for papers

           | lower level VTK api to do things not at all or well exposed
           | at the level of the PyVista API. Overall its a good project
           | and I hope it continues to improve and expand access to
           | powerful stuff in VTK minus the segfaults I occasionally run
           | into when attempting to do so from python...

       | recommend trying to embed it with complex Qt widgets, for
       | instance, and it's much better for surfaces and volumes than it
