It seems like it isn't needed, but it hasn't all been wrapped up into an easy to understand package yet: http://terathon.com/blog/projective-geometric-algebra-done-right/ http://terathon.com/blog/projective-geometric-algebra-done-r... http://terathon.com/blog/symmetries-in-projective-geometric-algebra/ http://terathon.com/blog/symmetries-in-projective-geometric-...
