method do not show the effect of accumulation.On the other hand, when we use (4) to convert an object, this conversion can easily be converted to the representation of the Quaternary element.For example, convert degrees a from Axis A to degree A. Q:Q. W = cos ():Q. V = sin (a) × A. // Q. V and A are three-dimensional vectors.It is also easy to accumulate the four-element. For example, if the original rotation state is Q1 and the applied rotation is Q2, the accumulative result isQ1 = Q2 * Q1 //:
