Frame.from_quaternion
- classmethod Frame.from_quaternion(quaternion, point=[0, 0, 0])[source]
Construct a frame from a rotation represented by quaternion coefficients.
- Parameters:
- quaternion[float, float, float, float] |
compas.geometry.Quaternion Four numbers that represent the four coefficient values of a quaternion.
- point[float, float, float] |
compas.geometry.Point, optional The point of the frame.
- quaternion[float, float, float, float] |
- Returns:
compas.geometry.FrameThe constructed frame.
Examples
>>> q1 = [0.945, -0.021, -0.125, 0.303] >>> f = Frame.from_quaternion(q1, point=[1., 1., 1.]) >>> q2 = f.quaternion >>> allclose(q1, q2) True
