Good point! Hmm... If I understand correctly, homogeneous coordinates have additional independent dimensions, but are many-to-one instead of constraining their parameters. Maybe normalized homogeneous coordinates? That's not a particularly interesting system. I'm now second guessing my definition of coordinate system...

Would points in a simplex qualify as a coordinate system? Their dimensions would have to sum to 1. That is, so-called "normalized" barycentric coordinates maybe, as opposed to standard barycentric coordinates? https://en.wikipedia.org/wiki/Simplex https://en.wikipedia.org/wiki/Simplex https://en.wikipedia.org/wiki/Barycentric_coordinate_system https://en.wikipedia.org/wiki/Barycentric_coordinate_system
