OK, but they are define a rotation in 3D space, do they not ?
My understanding is that a *unit* quaternion can be used to represent a rotation in 3-space, but an arbitrary quaternion is 4D.
OK. So going back to the original point. The intent in PQS is to use a quaternion solely for representing a rotation in 3D space. Putting quaternion in a 3D namespace makes sense to me from that viewpoint and should help to clarify its intended purpose. regards Andy Little
