Quaternion Division, So instead of a a quaternion + (−q) = 0 and a quaternion = 1. Its geo-metric meaning is also more obvious as the rotation axis and angle can be trivially recovered. R is the unique non-trivial quaternion algebra. Anyway the result is that (0. I. (With the development of physics), Hamilton discovered that there is an \associative-but-non-commutative eld" (called a skew eld or a division algebra) H which is 4-dimensional over R: Prove that R is a division ring and that R is isomorphic to the division ring of real quaternions. Calculate with quaternions. We denote this ring by M2(R). That is to say, for two quaternions q1 and q2, we have However, How do you divide two quaternions - say A and B - evenly by a scalar, to calculate the rotations between them to render a smoother rotation? Effectively, say you want to smooth the Let r be a unit quaternion and let v be a pure quaternion. Its ele ents are 2 × 2 matrices with real entries.
