The Oolong Engine,
A high performance game engine optimized for 3d graphics on the iPhone written by Wolfgang Engel. It is one of the powerful open source 3D engine that supports sophisticated 3d animation, skinned characters and more. It makes heavy use of PowerVR formats and brought Bullet physics to the iPhone.The Oolong Engine is written in C++ with some help from Objective-C. It will help you to create new games and port existing games to the iPhone and the iPod touch. The best part is, its free.
Oolong Engine 2.x is developed with the official iPhone SDK. So it requires a Mac OS X 10.5.x driven INTEL based Mac with at least iPhone / iPod touch OS 2.x and you need to be a registered developer to use it. Code is up at Google Code and under the permissive MIT license.
