There is an really impressive recent site here https://polyhedra.tessera.li/ https://polyhedra.tessera.li/ with a 3d viewer, it even has interactive animation where you can see how they transform into each other, for example an icosahedron gets changed into a diminished icosahedron and back.
- magnatiler 3y agoThis is such a cool site.
- olooney 3y agoThat site is amazing. I love the animated "operations" transitions. It's not on the same level as the above, but Wolfram Alpha has a list of the Johnson solids which shows each one unfolded into its 2D net[1]. Wolfram Alpha can also generate a 3D model[2] or list of vertices[3] for any Johnson solid using the `PolyhedronData[{"Johnson", n}]` dataset.
