opengl-es

Hi, I want to use Open GL ES 2.0 for a new game, but I have two questions.

Q: The first is how do I set up perspective views in Open GL ES 2.0 - do I need to include Open GL ES 1.0 and use glOrtho, or is there a new way?

Q: I want to use the 4th quadrant of a Cartesian co-ordinate system for my game and not use -0.5 to +0.5 for values on screen, how once the first question is answered can I achieve this?

Thanks

I have a simple iPhone application which uses OpenGL ES (v1) to draw a line based on the touches of the user. In the XCode Simulator, the code works perfectly. However, when I install the app onto an iPod or iPhone, the OpenGL ES view "flashes" when drawing the line. If I disable the line drawing… >>> More
