## GeoGebra 3D and 4D models

Discussion of tapertopes, uniform polytopes, and other shapes with flat hypercells.

### GeoGebra 3D and 4D models

I've been compiling a sort of library of polyhedra for quite some time now, and I've started to compile some polychora too. The latter collection is, at the moment, very, very incomplete, but my hope is to expand it over the next months, and hopefully make these figures accessible to people that can't afford Stella 4D.

And here's what I can offer at time of writing.

3D:
• All regular polyhedra
• All Archimedean and Catalan solids
• All nonprismatic uniforms and duals (other than the "infinite" duals)
• Most uniform compounds
• Some Johnson solids
• Prisms, bypiramids, antiprisms, trapezohedra, cupolae and their duals, for bases of up to 12 sides
4D:
• All convex regular polychora
• 16 Archimedean hypersolids (with mostly the simpler ones missing)

That’s a pretty cool collection too. I guess the difference is that I implemented 4D rotations directly, instead of making a file for every viewpoint of interest.
