sample_S2_cube_mesh

orix.sampling.sample_S2_cube_mesh(resolution: float, grid_type: str = 'spherified_corner') → Vector3d

Return vectors of a cube mesh projected on a unit sphere S2 [Cajaravelli, 2015].

Parameters:

resolution

Maximum angle between neighbour grid points, in degrees.

grid_type

Type of cube grid: "normalized", "spherified_edge" or "spherified_corner".

Returns:

vec

Vectors that sample the unit sphere.

Notes

Vectors are sampled by projecting a grid on a cube onto the unit sphere. The mesh on the cube can be generated in a number of ways. A regular square grid with equidistant points corresponds to the "normalized" option. "spherified_edge" corresponds to points such that the row of vectors from the [001] to [011] is equiangular. "spherified_corner" corresponds to the case where the row of vectors from [001] to [111] is equiangular.
