IOS SceneGraph

Before porting OpenSceneGraph to IPhone I decided that I needed to make sure I fully understood the differences between OpenGL and OpenGL ES. So I wrote this simple scenegraph system based off of OSG. It allowed me to brush up on my OpenGL ES while also giving me a better understanding of how OSG itself works. Source code is available to download on the right, it has no external dependencies, but I'm unsure how the file paths are setup (might not be relative).
