Pardon my OpenGL ignorance. I looked up chapter 3 in the Redbook and did a forum search but am not finding the answer to a simple question: If i have a 2D game in ortho mode, and it currently displays like this: and i want to flip it vertically like this: what matrix do i need to multiply it by? Or can i do that? The redbook didn't have them labeled (or i missed it) and matrices don't jive with my thought process well. Bonus points if you can explain why it works. Thanks for your help. I need it!

hey, that was simple enough. Thanks! I'm trying to write a wrapper that flips output text from FTGL without hacking FTGL to suit my needs. I think that's going a bit too far.

Thanks again.
