It is a 3D graphics API, i.e. it takes big lists of objects that you
maintain (like moving them about
in mathematical space) and draws them on screen to the criteria you specify
for example textures,
colour, lighting, etc.
- What I mean is, does it just draw the polygons and

OpenGL is nothing more than a graphics programming language. If you want
to do Quake, you`d need to program and engine to generate the world, ai,
creatures
and stuff and tell OpenGL to draw it.

There`s an OpenGL tutor available but you need an XServer to use it..!
(that`s UNIX)

Buy a book. or go to the comp.graphics.api.opengl newsgroup as they`ll be
able to answer your questions more thoroughly..
