sampling

Generation of grids on S2 (vectors) or SO(3) (rotations).

Functions

get_sample_fundamental([resolution, ...])	Return an equispaced grid of rotations within a fundamental zone.
get_sample_reduced_fundamental([resolution, ...])	Return a grid of rotations that rotate the Z-vector (0, 0, 1) into the fundamental sector of a point group's Laue group.
get_sample_local([resolution, center, ...])	Return a grid of rotations about a given rotation.
sample_S2(resolution[, method])	Return unit vectors that sample S2 with a specific angular resolution.
uniform_SO3_sample(resolution[, method, unique])	Uniform sampling of SO(3) by a number of methods.
sample_S2_cube_mesh(resolution[, grid_type])	Return vectors of a cube mesh projected on a unit sphere S2 [Cajaravelli, 2015].
sample_S2_equal_area_mesh(resolution[, ...])	Return vectors of a cube mesh on a unit sphere S2 according to equal area spacing [Rohrer et al., 2004].
sample_S2_hexagonal_mesh(resolution)	Return vectors of a hexagonal bipyramid mesh projected on a unit sphere S2.
sample_S2_icosahedral_mesh(resolution)	Return vectors of an icosahedral mesh on S2 [Schlömer et al., n.d.].
sample_S2_random_mesh(resolution[, seed])	Return vectors of a random mesh on S2.
sample_S2_uv_mesh(resolution[, hemisphere, ...])	Return vectors of a UV mesh on a unit sphere S2 [Cajaravelli, 2015].
