Description
Given a rotation quaternion (e.g. generated by axis_angle_to_quat axis_angle_to_quat AxisAngleToQuat AxisAngleToQuat AxisAngleToQuat
),
the operator quat_rotate_point_3d quat_rotate_point_3d QuatRotatePoint3d QuatRotatePoint3d QuatRotatePoint3d
can be used to rotate a 3D point
(Px Px Px Px px
, Py Py Py Py py
, Pz Pz Pz Pz pz
). The rotated point is returned in
(Qx Qx Qx Qx qx
, Qy Qy Qy Qy qy
, Qz Qz Qz Qz qz
).
The rotation of a point x by an unit quaternion q is given by
corresponds to the conjugation of a quaternion q
(see quat_conjugate quat_conjugate QuatConjugate QuatConjugate QuatConjugate
). 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_3d quat_rotate_point_3d QuatRotatePoint3d QuatRotatePoint3d QuatRotatePoint3d
does not check whether
Quaternion Quaternion Quaternion Quaternion quaternion
is a unit quaternion. If Quaternion Quaternion Quaternion Quaternion quaternion
is not
a unit quaternion, the result of this operator is not defined.
