to_axis_angle

Quaternion.to_axis_angle()

Convert a quaternion to the axis angle rotation formulation.

Returns:

tuple

((ux, uy, uz), theta) containing the rotation axes expressed as X, Y, Z components of the unit vector u and the rotation angle theta expressed in radians.

Examples

>>> from ansys.aedt.core.generic.quaternion import Quaternion
>>> q = Quaternion(1, 1, 1, 1)
>>> (axis, angle) = q.to_axis_angle()
>>> axis
