Should it in fact > be the opposite (i.e., if the angle is changed at all)? Er, not the opposite, I misread angle as centre point. However the comment below still stands: > I don’t know > what sort of problems a user agent may have if an attempt is made to > perform a paced animation of a rotation that includes a change in centre > point, since the distance formula is clearly defined. I suggest that it > be reworded as: > > Note that the distance formula for rotation transformations is defined > only in terms of the angles and not the center points. Thus, if paced > animation of a rotation transformation that does include a change in > center point is performed, the result may not look truly paced. -- Cameron McCormack ≝ http://mcc.id.au/
