Project: Shortest Path on the Surface of a Tetrahedron, Cube, Octahedron

For polyhedra, the shortest distance between two points along the surface is not an obvious formula. This demonstration calculates the shortest possible path across the surface of the selected regular polyhedron (tetrahedron, cube or octahedron). Select which polyhedron to use, and then provide two points on the surface of the polyhedron. Use sliders to specify the spherical coordinates of each point.
