Quaternions are an alternate way to describe orientation or rotations in 3d space using an ordered set of four numbers. They have the ability to uniquely describe any 3d rotation about an arbitrary axis and do not suffer from a problem using euler angles called gimbal lock.

Quaternions are a set of 4-dimensional vectors that are used to represent rotations in computer graphics, they were discovered by William Hamilton as an extension of 2d complex numbers to a 3d equivalent.

This article covers the definition of a quaternion, its notation and operations.
