Schlegal diagram coordinates for 3d viewports

[Drixxen_Vellumer]

I am exceedingly interested in dimensional visualization, going so far as to enact a biovisualizer within the trance states of meditation. I am currently working on a project of formatting polychora for manipulation in 3d modeling programs. -- can anyone point me in the right direction of coordinate acquisition of 4d cells and the like in terms of schlegal diagrams? I am not knowledgeable in specific mathematic processes and the information found in the overweb is insufficient. (This endeavor will be outside of usual scripting and set for actual in-program model building)

I want to have pinpoint vertex coordinates of the perspective projection and viable coordinates for the translations of said vertexes when rotated along the Xw, Yw, and Zw planes. I am exceedingly interested in learning and do not mind doing copious amounts of work for the return of this
