I'm trying to display my scene with an orthogonal projection, with position 0,0 in the lower left corner of the screen. So far I have gotten an orthogonal projection to work, but when I've tried to move the origin (with glViewport) I only get a quarter of the screen rendering.

Here's my code

Can anyone help?

Why did you put your code on Pastebin? – Nicol Bolas Nov 18 '12 at 22:47
