rotate_vector

Quaternion.rotate_vector(v)

Evaluate the rotation of a vector, defined by a quaternion.

Evaluated as: "q = q0 + q' = q0 + q1i + q2j + q3k", "w = qvq* = (q0^2 - |q'|^2)v + 2(q' • v)q' + 2q0(q' x v)".

Parameters:

vtuple or List

(x, y, z) coordinates for the vector to be rotated.

Returns:

tuple

(w1, w2, w3) coordinates for the rotated vector w.

Examples

>>> from ansys.aedt.core.generic.quaternion import Quaternion
>>> q = Quaternion(0.9238795325112867, 0.0, -0.3826834323650898, 0.0)
>>> v = (1, 0, 0)
>>> q.rotate_vector(v)
