Spherical fraction
WebApr 13, 2016 · In the classical case, the spheres are all of the same sizes, and the space in question is three-dimensional space (e.g. a box), but the question can be extended to consider different-sized spheres, higher (or lower) dimensions, or different types of shapes (e.g. a tetrahedron). WebThe proposed approach is based on the spherical fraction harmonic decomposition, similar to that of spherical harmonics decomposition for the whole sphere. The definition of these functions is ...

In geometry, a sphere packing is an arrangement of non-overlapping spheres within a containing space. The spheres considered are usually all of identical size, and the space is usually three-dimensional Euclidean space. However, sphere packing problems can be generalised to consider unequal spheres, spaces of other dimensions (where the problem becomes circle packing in two dimensions, or hypersphere packing in higher dimensions) or to non-Euclidean spaces such as hyp… Web1 day ago · spherical namespace google.maps.geometry. spherical namespace Utility functions for computing geodesic angles, distances and areas.
