I want to visualize an algebra that is not directly supported by ganja.js, but very close to 2d CGA \R_{3,1} . Namely \R_{3,2} this algebra describes oriented spheres and like \R_{3,1} describes spheres, see Jupyter Notebook Viewer.

For my purposes, it would be good enough if I could easily take a multi-vector in \R_{3,2}, drop all components that involve `e5`

, interpret the result as an element of \R_{3,1} and graph that.

However, I don’t know how to that, any ideas?
