Displaying 3D objects

Hi.

How to display 3D objects in a CCLayer?

Is there any good library to do this?

Thanks.

Jose

How did you generate 3D objects?
Generated by Maya?

I just would like to show a hand defined object, like a cube.

My idea is to create a function that takes the object definition (like vertices and textures coordinates) and draws in a CCLayer or CCNode.
