First images (in temporal order) contains segments and planar faces. In the following pictures the geometry is pumped to the surface of hypersphere; in this way stereoscopic projection becomes bijective and edges and faces becomes circular arcs and spherical domes.

Style is inspired by some oriental *glass and brass* lamps.

*Demitesseractic Tetractic Honeycomb* is really ugly. *Tesseractic Tetracomb*
is a desperate attempt; the 3x3x3x3 4D chessboard can be used to play *tic tac toe tuc* game
(I invented the game's name but game still no).

5D solids or higher dimensions are projected by applying iteratively the stereoscopic projection. The final projection is not conformal nor bijective.

Duopyramid - C++ Source Code - Projection of 6,4-duopyramid (blue) with its dual Duoprism (in transparent red). In the last row, the duopyramid is projected by a direction perpendicular to the first one; so the two parameters (6,4) seem to be reversed. Indeed, asymmetry is due to the projection: the two parameters are symmetric in 4D. | |
