Quaternions are a number system that has become increasingly useful for representing the rotations of objects in three-dimensional space and has important appli

In addition to these theoretical issues, we also address some computational questions. We develop straightforward formulas for converting back and forth between

This self-contained text presents a consistent description of the geometric and quaternionic treatment of rotation operators, employing methods that lead to a r
