Hey, I'm relatively new to OpenGL but I have a little experience in C and I was wondering how I would set the pixel coordinates of an OpenGL windows. Its a little hard to explain what I mean but for example if I would like to instead of having (x,y) coordinate (0,0) bang in the center of the windows, have it place to the top left of the screen and instead of having x ranging from say -13.0f to 13.0f (as in the horizontal coordinates of the screen, noting that x=0 would be the center in this case), have it ranging from -100.0f to 100.0f.
If you understand what I mean, please help me out with a function or some links to helpful material. If you don't understand what I mean I can draw a diagram or something to try and explain it better.
Cheers,
Jonathon.
