I don't like the separation of "three_d" and "two_d" - where quaternions should be put then - "four_d" ?
My rationale is that quaternions exist in a 3D space. OTOH complex would be in two_d because it exists in a 2D space.
quaternions are 4D (1, i, j, k), where complex is 2D (1, i).
OK, but they are define a rotation in 3D space, do they not ? regards Andy Little
