WebAug 23, 2024 · Erik Blake on 13 May 2024. Just as with vectors, the cosine of the rotation angle between two quaternions can be calculated as the dot product of the two quaternions divided by the 2-norm of the both quaternions. Normalization by the 2-norms is not required if the quaternions are unit quaternions (as is often the case when describing rotations).
