I was playing around with some geographic features of Mathematica this morning and ran across an interesting example in the documentation for the
PolyhedronProjection function given here. Here’s what you get when you project a map of the earth onto each of the five regular (Platonic) solids.
How the images were made
At first I right-clicked on each image and saved as graphic files. This produced low quality images, even when I saved as SVG. I got better resolution by using the
Export command and specifying the
The default view of the tetrahedron was face-on, so it looked like a flat triangle. By changing the
ViewPoint I was able to get something that’s more clearly three dimensional.
By the way, you can use
PolyhedronProjection to project onto more exotic polyhedra than the Platonic solids. For example,
Export["rhomb.png", PolyhedronProjection["ParagyrateDiminishedRhombicosidodecahedron"], ImageResolution -> 72, ImageSize -> Large]
One thought on “Projecting the globe onto regular solids”
Those solids can be unfolded, creating a flat map of the earth. https://www.bfi.org/about-fuller/big-ideas/dymaxion-world/dymaxion-map
