Description

Given a rotation quaternion (e.g., generated by axis_angle_to_quataxis_angle_to_quatAxisAngleToQuatAxisAngleToQuataxis_angle_to_quat), the operator quat_rotate_point_3dquat_rotate_point_3dQuatRotatePoint3dQuatRotatePoint3dquat_rotate_point_3d can be used to rotate a 3D point (PxPxPxpxpx, PyPyPypypy, PzPzPzpzpz). The rotated point is returned in (QxQxQxqxqx, QyQyQyqyqy, QzQzQzqzqz).

The rotation of a point x by an unit quaternion q is given by

corresponds to the conjugation of a quaternion q (see quat_conjugatequat_conjugateQuatConjugateQuatConjugatequat_conjugate). Note that x will be transformed into quaternion form to perform the rotation. This is done by setting the real part to zero and the three imaginary components to the three components of x.

Attention

The operator quat_rotate_point_3dquat_rotate_point_3dQuatRotatePoint3dQuatRotatePoint3dquat_rotate_point_3d does not check whether QuaternionQuaternionQuaternionquaternionquaternion is a unit quaternion. If QuaternionQuaternionQuaternionquaternionquaternion is not a unit quaternion, the result of this operator is not defined.
