Quaternion

A quaternion is a mathematical tool used to represent rotations in three-dimensional space efficiently and smoothly. Unlike traditional methods that can cause problems like gimbal lock, quaternions encode orientation with four numbers: one real part and three imaginary parts. They allow for seamless interpolation between rotations, making them essential in computer graphics, robotics, and aerospace for accurately controlling and simulating orientation without distortion or complexity. Essentially, quaternions provide a compact, robust way to handle 3D rotations, improving stability and performance in various technical applications.
