Surfed around a bit more.
Looks like some of the code out there has checks for degenerate objects, so a
degenerate triangle check / flag / excision might be a good feature.
Just going to plop these here as a historical record (some are looking quite
old) and perhaps to inspire some ideas.
A sphere-and-cylinder wireframe representation would be a great adaptation too.
I'm not sure how the mesh2 code works under the hood, but I'm wondering if a
vertex-order checking needs to be done to ensure the proper ordering of the
vertices so that the face normals are in the correct direction.
