Quaternions

Quaternions are a mathematical system used to represent orientation and rotation in three-dimensional space. Unlike simple angles or vectors, quaternions avoid issues like gimbal lock and provide smooth, continuous rotation calculations. They consist of one real part and three imaginary parts, combining to encode an object's direction and rotation efficiently. Quaternions are widely used in computer graphics, robotics, and aerospace for precise and stable rotation control, making it easier to animate or navigate objects without complex calculations or sudden jumps in orientation.
