However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used special globes and instruments to make measurements and teach.

The triangles are orientated in a clockwise manner, triangles that span more than the hemisphere are removed. # delaunay.centers. The array of centers in spherical coordinates; the first t centers are ...

A Python module for obtaining Voronoi diagrams on the surfaces of spheres, including the calculation of Voronoi region surface areas. Applications may range from calculating area per lipid in ...

We describe a fast surface reconstruction approach that takes random points distributed near the surface of a sphere as input, and generates as output a Delaunay surface mesh and its dual Voronoi ...

Gotsman et al. (SIGGRAPH 2003) presented the first method to generate a provably bijective parameterization of a closed genus-0 manifold mesh to the unit sphere. This involves the solution of a large ...

Most trigonometry students look at triangles on a flat surface. However, people from ancient astronomers to modern navigators calculated the arc lengths and angles of triangles on a sphere. They used ...
