Drawing a 2D Hud on a 3D OpenGL ES scene is a common task when developing games.

To do this without any distortion in OpenGL ES you need to draw your HUD through a matrix different from the projection matrix used for 3D objects.

Jeff LaMarche, co-author of Beginning iPhone 3 Development, and More iPhone development has added a new tutorial on Drawing a Hud Display in OpenGL ES.

In the tutorial Jeff takes you through the process of adding a simple HUD to a 3D Scene.

Be sure to check out the iPhone OpenGL ES resources list for more OpenGL ES resources.
