3D rendering extension for cocos2d-iphone, written in Objective-C.

Cocos3d is a 3D rendering extension to cocos2d-iphone, written in Objective-C. It is not a standalone renderer.

Cocos3d adds to cocos2d-iphone a full 3D modelling space, including 3D mesh models, perspective projection cameras, materials, and lighting. With cocos3d 3D models exported from 3D editors such as Blender, 3D Studio Max or Cheetah3D can be used. 3D models can also be created dynamically with Objective-C code. Users can interact with 3D objects through touch events.

This is the official cocos3d web page.
