This wiki is a repository of information about **Projective Geometric Algebra**, and specifically the four-dimensional Clifford algebra $$\mathcal G_{3,0,1}$$. This algebra subsumes the conventional theories that include homogeneous coordinates, Plücker coordinates, quaternions, and dual quaternions.

Please note that this wiki is still under construction and new information is actively being added.
