WebA quaternion is a mathematical construct that consists of four real numbers. These numbers represent an extension of a complex number. Remember that complex numbers have a real and an imaginary part. Quaternions have one real and three imaginary parts, so their representation is as follows: Q = w + xi + yj + zk.
