I didn't know about this event until seeing the site making the technology page on Digg, I found the keynote very informative and think anyone else interested in IPhone game development should also watch it.

Apple press release

To sum it up from a developer's perspective...
"Quarterly iPhone units sold were 6,892,000 compared to 1,119,000 in the year-ago-quarter. "

Almost 7 million IPhones sold in one quarter ready for you to target your app.

Another gem found at Google Code:

iGLU is an implementation of the OpenGL Utility Library (GLU) for iPhone OS.

iGLU does not include GLU features that depend on OpenGL functionality missing in OpenGL ES 1.1.

Available features:

* Matrix manipulation
* Polygon tessellation

Missing features:

* Mipmapping
* Quadrics
* NURBS

SIO2 is a 3D engine for the IPhone using OpenGL ES, OpenAL and various other technologies.



The engine is built around Blender, allowing a WYSIWYG approach to visualization. The down side for me is I don't like Blender. It is too heavy weight for producing art assets for a small screen. I much prefer the shareware application Milkshape 3D, which is elegantly simple.

While investigating alternatives for timing in the game loop, I came across a 2D game engine that seems interesting. It is called Cocos2d and it is designed specifically for 2D applications in need of hardware accelerated graphics.

What is most impressive to me is the integration with a 2D physics engine.

The Google Code site has other interesting code resources for developers looking for examples of applications running on Apple IPhones.
