Parameters

quaternion ([float, float, float, float] | Quaternion) – Four numbers that represents the four coefficient values of a quaternion.

Returns

Rotation

Examples

>>> from compas.geometry import allclose
>>> q1 = [0.945, -0.021, -0.125, 0.303]
>>> R = Rotation.from_quaternion(q1)
>>> q2 = R.quaternion
>>> allclose(q1, q2, tol=1e-3)
True
