there is one element per possible axis). This could be called R[x]/R+ or R[x]/R respectively. Also, this could be called "spherical space" and "projective spherical space", respectively.
Everywhere where I said R[x], please replace by R^N, which is assumed to be a vector space. R[x] can be used as a vector space, but it's mainly considered as a ring (R^n extended with a vector*vector product), so it can get confusing sometimes.
