This session is intended for experienced iPhone programmers who are unfamiliar with OpenGL ES and the mathematics and concepts of three dimensional graphics. It starts from the beginning, and talks about the architecture of OpenGL ES works and how it's implemented in the two GPUs currently available in iPhones and then goes on to review the basic mathematics of three dimensional graphics. Jeff looks at creating 3D geometry in third party applications and looks at the optimal ways to submit geometry to OpenGL ES, while discussing the differences between OpenGL ES 1.1, which is available on all iPhones and OpenGL ES 2.0, which is only available on the iPhone 3Gs and the 32mb and 64mb third generation iPod touch. Though starting from the beginning, this session crams a lot of information and sample code into an hour, giving you everything you need to hit the ground running with 3D programming on the iPhone.
