  1. The set of polyhedra that can be converted into Apollonian gaskets via sphere-plane mapping is quite limited. The face polygons should be regular, the edge midpoints should all lie on the same sphere, and the vertices should be 3-fold. There are some Platonic solids that work, and I've showed all of these earlier. It turns out that Archimedean solids with 3-fold vertices work too. So here's a truncated octahedron, also showing a progressive view of the gasket iteration.

  2. #3DPrinting #TruncatedOctahedron #Gears Yay! I finally solved the "simple" problem.

    It was indeed obvious once I knew the answer. Not much complicated maths at all once I found out that I needed to use the logarithmic spiral formula:

    x = ๐‘Ÿโ‹…๐‘’^(โˆ’yโ‹…๐‘ ๐‘–๐‘›(๐œŒ) / ๐‘›)

    z = ๐‘Ÿ โˆ’ ๐‘Ÿโ‹…๐‘ก๐‘Ž๐‘›(๐œŒ)
