I think we went over the 3d rotation using quaternions a bit fast. Do you have an example of how the quaternion would be used for an example? I am not sure how I would compose a quaternion if I wanted to rotate in certain amounts in the x/y/z direction

@cou This seems helpful. The three Euler angles are mapped to the u axis, i.e. i, j, k. https://en.wikipedia.org/wiki/Conversion_between_quaternions_and_Euler_angles

During the class, I was confused by the q-xq calculation because of considering x as times instead of the vector of the point to rotate. Thus this is just a note to remind if someone has the same problem.
