Is there a 3D library for objective-c like papervision or away3D for actionscript

Is there a 3D library for objective-c like papervision or away3D for actionscript? To clarify, I'm writing the app in objective-c.

All I really need to do is contruct a 3D开发者_Go百科 sphere programmically and attach raster images and buttons around the inside of the sphere.

Many thanks in advance.

cocos3d is a nice, idiomatic Objective-C library for rendering 3D on iOS platforms.

OpenGL would be the best way to do 3D I would imagine.
