We propose a new method for the construction of new "nice" configurations of vectors on the unit sphere S d with the use of spaces of spherical harmonics.doi:10.1007/s11253-010-0407-6Bondarenko, A.Springer USUkrainian Mathematical Journal...
Spherical Harmonics (SH) is a frequency-based space that represents functions over a sphere. The SH is defined as the angular portion of a set of solutions to Laplace’s equation using the spherical coordinates of the 3D object, organized by their angular frequency. For the specific case of ...

Spherical harmonics是可以重构任何函数的基函数,研究二维函数的单位球。 SH是定义在单位球表面的基函数,表示在球面坐标下。 球坐标系 其中r=1。 SH的一般形式是 实际形式,也就是接下来会用到的形式是 最终形式是 公式中的项: Plm是勒让德多项式,定义在[-1,1]范围内,递归式是 ...
The code is based on the spherical harmonic discrete ordinate method (SHDOM) which evaluates a source function including anisotropic scattering in spherical harmonics and implicitly solves the static radiative transfer equation with ray tracing in discrete ordinates. We implement treatments of time ...
