Rn affine spaces are open subspaces of projective spaces, which are quotients of vector spaces.
Rn + Rn-1 + ... + R0 difference is geometry half sphere vector space zero zero and infinity are balanced lines in P2 or more generally hyperplanes in Pn always do intersect
Infinity is represented by the z axis which is perpendicular to the represented plane. |
