Rotate around an arbitrary 3D vector. This method is only applicable to 3D vectors. Use the
angle parameter to specify the rotation angle and the
v parameter to specify the vector to rotate around. The
v vector does not need to be aligned to any axis or normalized, but it must be a 3D vector and it cannot be a vector of zeros.
The vector’s rotation will follow the right-hand rule. Using your right hand, point your thumb in the direction of the vector to rotate around. Your fingers will curl in the direction of rotation when the
angle parameter is positive.
rotate_around(angle: float, v: Py5Vector3D) -> Py5Vector3D
angle: float - angle of rotation, measured in radians
v: Py5Vector3D - 3D vector to rotate vector around
