Summary

Detail Description:
It has 6 sets of rotations of 90 frames each. All of these rotate in steps through ${\displaystyle \theta =i2\pi /steps}$ on the horizontal (H) projection vector. The 6 sets of H,V,Z projection basis vectors are: ${\displaystyle ((\theta ,0,0),(\theta ,\theta ,0),(\theta ,{\frac {1}{2}},{\frac {1}{2}}),(\theta ,0,{\frac {3\pi }{4}}),(\theta ,{\frac {\pi }{2}},{\frac {\pi }{4}}),(\theta ,{\frac {\theta }{2}},{\frac {\theta }{4}}))}$.

4D perspective projection is accomplished by dividing x,y,z vertex dimensions by w+1 after 4D rotation (but before projection to 3D).
