As part of my donated work in Godot Engine, my approach is to improve manifold https://github.com/elalish/manifold to get a "geometric kernel"

I think I've succeeded and many CAD tools use manifold for geometric kernels on 3d boundary meshes.

I was able to get Godot Engine and Blender to adopt elalish/manifold.

List of CAD tools that adopted elalish/manifold.
