How to use the mesh functions from the Python library Manifold3D in Manim.
This code is for the Cairo renderer - some changes will probably be necessary for the opengl renderer, however since the opengl-renderer natively works with triangular meshes, it should be quite feasible.
Two examples: a simple sphere and the intersection between a sphere and a cube
