Summary[edit]

Description
English: Frame synchronized comparison of the 4D orthogonal projection (left) and 4D perspective projection (right) rotated in 4D then projected and displayed in a 3D perspective view.

Author Jgmoxness

Detail Description:
It has 6 sets of rotations of 90 frames each. All of these rotate in steps through on the horizontal (H) projection vector. The 6 sets of H,V,Z projection basis vectors are: .

4D perspective projection is accomplished by dividing x,y,z vertex dimensions by w+1 after 4D rotation (but before projection to 3D).
This is constructed from VisibLie_E8 found on TheoryOfEverything.org archive copy at the Wayback Machine with the following settings:
