object collision - how to begin

hello there,
i’m looking for some info around object collision using opengl. i’m a little bit confused.
where and how to start?
how is it with multibody systems?
is it possible to detect collision according mesh?
how does it work?
each feedback is helpfull 4 me .

THANX.

OpenGL has nothing to do with collision detection. You need to provide that api yourself, or use one of the publicly available collision detection libraries.

Where can those publicly available collision libraries found?

Just do a search on Google for collision detection library and it will return thousands of links concerning the multitude of available libraries (some commericial, some free).
