3d / 2.5d game library for iphone and pc

I'm trying to make a 2d shooter game with 3d background.

The player and enemies are essentially just quads with textures.

The background will be simple 3d polygons with textures and some fog and light.

Therefore, I don't need a really powerful 3d library.

I tried Unity3D and Torque2D, but I don't like to use their GUI 开发者_运维百科editors. I prefer to work with code.

So, is there a cross platform (mainly windows and iPhone) 3d / 2.5d game library, commercial or open source?

I assume it will be only limited to c, c++, and object-c due to apple's new ToS.

Cocos2D works on iPhone.

I recall that there is an Ogre3D port to iPhone, but I don't remember its name just now.

If you just want some simple images you can just use OpenGL ES. I've heard it's quite nice to program with it on iPhone. Also, take a look at parallax. If you want to do 2.5D games I think it's a must.
Good luck
