Hello,
Can someone explain to me what quaternions are, and why they are useful for fx?
I know they are something to do with rotation, but I don't know what!

(…) quaternions provide a convenient mathematical notation for representing orientations and rotations of objects in three dimensions. Compared to Euler angles they are simpler to compose and avoid the problem of gimbal lock. Compared to rotation matrices they are more numerically stable and may be more efficient.

skk.
hint: If you want to know what quaternions are in essense, it's vital to get into complex numers a bit.
