[FRIAM] mathematicians computer graphic-ians — a little? help please

[Prof David West]

yes. I did see another that seemed to show the cube in the center not retaining its squares

And there are 'families' of 2-D patterns that an origami expert can look at and tell you if the eventual 3-D figure will have 2, 3, or 4 legs. How it is possible to 'see', in your mind, the 3-D in the 2-D?

>> Two) a quick look at several animated hyper-cubes show the 'interior' cube remaining cubical as the hypercube is manipulated. Must this always be true, must the six facets of the 3-D cube remain perfect squares? What degrees of freedom are allowed the various vertices of the hyper-cube?
>> 
>> Three) can find static hyper— for the five platonic solids, but not animations. Is it possible to provide something analogous to the hypercube animation for the other solids? I think this is a problem in manifolds as many of you have talked about.
>> 
>> Question: If one had a series of very vivid, very convincing, visions of animated hyper-platonic solids with almost complete freedom of movement of the various vertices (doesn't really apply to hypersphere) — how would one go about finding visualizations that would assist in confirming/denying/making sense of the visions?
