If I had to describe Quaternions to someone I would first try to explain a Plane (Ax + By + Cz + D = 0) to them. ABC being a (normal) direction that the Plane is pointed towards and D being the distance from the origin.
A Quaternion from what I believe is just the same but instead of distance it just encodes the rotation around that direction as a fixed axis. (Instead the angle stored is half etc).
Feel free to correct me if I'm wrong, I'm not a math-heavy person.

- raincole 2y agoI know it's a tradition to bash Americans, but I'm quite sure in any country, Ax + By + Cz + D = 0 is a plane isn't common sense.

(Instead the angle stored is half etc). The first part kinda makes sense, but I have no idea what the paranthetical is intended to mean.
