to_matrix

Quaternion.to_matrix() → ndarray

Return the unit quaternions as orientation matrices [Rowenhorst et al., 2015].

Returns:

om

Array of orientation matrices after normalizing the quaternions.

Examples

>>> from orix.quaternion import Quaternion
>>> Q1 = Quaternion([[1, 0, 0, 0], [2, 0, 0, 0]])
>>> np.allclose(Q1.to_matrix(), np.eye(3))
True
>>> Q2 = Quaternion([[0, 1, 0, 0], [0, 2, 0, 0]])
>>> np.allclose(Q2.to_matrix(), np.diag([1, -1, -1]))
True
