WebA quaternion is technically four numbers, three of which have an imaginary component. As many of you probably know from math class, i is defined as sqrt (-1). Well, with quaternions, i = j = k = sqrt (-1). The quaternion itself is defined as q = w + x i + y j + z k. w, x, y, and z are all real numbers. The imaginary components are important if ...
