File talk:Stereographic polytope 120cell.png

Interesting representation. It is labeled as Stereographic projection in the article 120-cell. I don't think this can be correct. At least I would expect straight edges to be mapped as straight edges, like Image:Hypercube.svg, so it must be something a little different. I'd appreciate a correct labeling of the projection.

P.S. looking at website [1], and the regular polyhedra representaions, it appears these are "spherical polytopes", polytopes mapped onto a hypersphere before projecting onto 3-space or 2-space. That would explain the curved edges. Tom Ruen 18:03, 28 July 2006 (UTC)[reply]
