'How can I tell if a mesh is a plane from a topological point of view?
I need to distinguish between meshes that can be topologically transformed to a plane (a triangulated square, for example) and those that can not (a cube or a spherical mesh).
How would I do that - ideally in python, with a representation based on nodes and edges.
Even better if I can tell toruses etc. but that’s just a nice to have.
