sample_S2_cube_mesh#
- orix.sampling.sample_S2_cube_mesh(resolution: float, grid_type: str = 'spherified_corner') Vector3d [source]#
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.
