get_points_in_sphere

diffsims.utils.sim_utils.get_points_in_sphere(reciprocal_lattice, reciprocal_radius)

Finds all reciprocal lattice points inside a given reciprocal sphere. Utilised within the DiffractionGenerator.

Parameters:

reciprocal_latticediffpy.Structure.Lattice

The reciprocal crystal lattice for the structure of interest.

reciprocal_radiusfloat

The radius of the sphere in reciprocal space (units of reciprocal Angstroms) within which reciprocal lattice points are returned.

Returns:

spot_indicesnumpy.array

Miller indices of reciprocal lattice points in sphere.

cartesian_coordinatesnumpy.array

Cartesian coordinates of reciprocal lattice points in sphere.

spot_distancesnumpy.array

Distance of reciprocal lattice points in sphere from the origin.
