Rotation.from_quaternion

classmethod Rotation.from_quaternion(quaternion)

Calculates a Rotation from quaternion coefficients.

Parameters

quaternion (compas.geometry.Quaternion or list) – Four numbers that represents the four coefficient values of a quaternion.

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
