In many articles I read of the quats. Quat is four float values, but I don''t know what I use the quat. Do you know some goal of the quat ?

Quaternions is games are used to represent rotations. The best resource for quaternions I know of is:

Using Quaternions to Represent Rotation

It isn't OpenGL specific, but it does give matrix conversions for quaternions. You should be able to implement the matrices with not too much trouble -- any basic 3D book should show you.

Good Luck!
