Quaternion is a 4 dimensional vector that is used to represent a rotation. It mainly exists to perform SLERP (spherical-linear interpolation) between two rotations. Multiplying quaternions also cheaply reproduces rotation sequences. However quaternions need to be often renormalized, or else they suffer from precision issues.
