HaloMods "Classic" Read-only Archive

What programming languages do they use to incorporate 3D graphics into a game, like Halo for example. Which would be the simpliest game where I can use 3D models made in another program, ie. 3ds max/gmax.

Thanks a bunch

I don't really understand. Is this 2 different questions. Anyways I'll answer it best I can.

Most games are programmed in C++ and the graphics for most games are set up with DirectX which enables you to display the graphics and such.
