Hi guys, I've just started iphone development. I've managed to get 2D graphics working in open gl along with rudimentary 3D graphics. The effect I'm after is getting 50/50(top/bottom) split screen with 2D graphics in one view and a 3D view in the other... Imagine like a DS game where you get, say, a map on the bottom screen and the game view in the top (for example only, obviously thats not a great use of iphone screen-space). Unfortunately my experience with 3D and Open GL is pretty limited so i'm not even sure what techniques or methods I should be googling for to achieve this. Thanks.
