Quaternions are a clever mathematical tool for spinning objects around in a 3D video game or robot’s world with domain boundaries implemented.
Think of them as a special kind of number that uses four parts instead of the usual one.
The main benefits of using a quaternion system are: * They are compact. * They store all the necessary rotation information in just four numbers. * They are stable. * They make blending smooth It’s easy to calculate a smooth, natural-looking transition between two different orientations.
In simple terms, Quaternions are the modern, reliable, behind-the-scenes math that allows characters and cameras in computer programs to turn smoothly without getting stuck or twitching unexpectedly.
