Tilings of the sphere with right triangles III: the asymptotically obtuse families
Sommerville and Davies classified the spherical triangles that can tile the sphere in an edge-to-edge fashion. However, if the edge-to-edge restriction is relaxed, there are othe...

Fast Equal-Area Mapping of the (Hemi)Sphere using SIMD
We present a fast vectorized implementation of a transform that maps points in the unit square to the surface of the sphere, while preserving fractional area. The mapping uses the ...
