apply_transform

apply_transform(coords: ndarray, M_rotation: ndarray, v_translation: ndarray) → ndarray

Apply a roto-translational transform to a set of points, i.e. the atomic positions of atoms that are to be added from the template to the original reference frame.

Parameters:

• coords ((M, 3) array) – Points to transform.

• M_rotation ((3, 3) array) – Rotation matrix.

• v_translation ((3,) array) – Translation vector.

Return v_transformed:

Returns the transformed coordinates: M_rotation @ coords + v_translation.

Return type:

(M, 3) array
