legacy_generate_triplets(i_where: numpy.ndarray, j_where: numpy.ndarray, distance_matrix: numpy.ndarray, knot_sequences: List[numpy.ndarray]) → Tuple

Identify unique “i-j-j’” tuples by combining provided i-j pairs, then compute i-j, i-k, and j-k pair distances from i-j-k tuples,

distance matrix, and knot sequence for cutoffs.

Parameters

• i_where (np.ndarray) – sorted “i” indices

• j_where (np.ndarray) – sorted “j” indices

• distance_matrix (np.ndarray) –

• knot_sequences (list of np.ndarray) –

Returns

array of shape (n_triangles, 3)

Return type

tuples_idx (np.ndarray)
