Hi,

I have a question and I apologize if it is too newbish. I have been for a while now trying to learn OpenGL but I cannot understand how its coordinate systems works. I know coordinate geometry as I did some math long ago as well as equations (linear, polynomial et al) which I think are enough to get me started with math of OGL. But I cannot get hold of how OGL maps its coordinates system with respect to the screen of the computer.

Google was of little help on this and any link/Explanation is warmly welcome and appreciated.

Thanks!
