uf3.data.geometry.sort_image_indices

sort_image_indices(a_indices: numpy.ndarray, b_indices: numpy.ndarray, c_indices: numpy.ndarray, cell: numpy.ndarray) → Tuple[numpy.ndarray, numpy.ndarray, numpy.ndarray]

Sort image indices based on distance to origin.

Parameters

• a_indices (np.ndarray) – flattened coordinate array of image indices in a direction.

• b_indices (np.ndarray) – flattened coordinate array of image indices in b direction.

• c_indices (np.ndarray) – flattened coordinate array of image indices in c direction.

• cell (np.ndarray) – 3x3 array of a, b, c lattice vectors.

Returns

Sorted, flattened coordinate arrays of image indices in each direction.
