scipy.spatial.transform.Rotation.
magnitude#
- Rotation.magnitude(self)#
- Get the magnitude(s) of the rotation(s). - Returns:
- magnitudendarray or float
- Angle(s) in radians, float if object contains a single rotation and ndarray if object contains multiple rotations. The magnitude will always be in the range [0, pi]. 
 
 - Examples - >>> from scipy.spatial.transform import Rotation as R >>> import numpy as np >>> r = R.from_quat(np.eye(4)) >>> r.as_quat() array([[ 1., 0., 0., 0.], [ 0., 1., 0., 0.], [ 0., 0., 1., 0.], [ 0., 0., 0., 1.]]) >>> r.magnitude() array([3.14159265, 3.14159265, 3.14159265, 0. ]) - Magnitude of a single rotation: - >>> r[0].magnitude() 3.141592653589793
