scipy.spatial.transform.Rotation.reduce¶

Rotation.
reduce
()¶ Reduce this rotation with the provided rotation groups.
Reduction of a rotation
p
is a transformation of the formq = l * p * r
, wherel
andr
are chosen from left and right respectively, such that rotationq
has the smallest magnitude.If left and right are rotation groups representing symmetries of two objects rotated by
p
, thenq
is the rotation of the smallest magnitude to align these objects considering their symmetries. Parameters
 left
Rotation
instance, optional Object containing the left rotation(s). Default value (None) corresponds to the identity rotation.
 right
Rotation
instance, optional Object containing the right rotation(s). Default value (None) corresponds to the identity rotation.
 return_indicesbool, optional
Whether to return the indices of the rotations from left and right used for reduction.
 left
 Returns
 reduced
Rotation
instance Object containing reduced rotations.
 left_best, right_best: integer ndarray
Indices of elements from left and right used for reduction.
