I recommend this engine 3d

Hi, all

A graphics engine that can teach many things.

An easy to use managed graphics engine. Utilises OpenGL, Direct3D9, and Xna through an abstraction layer. Accompanied by a number of other helpfull tools, for example to simplify input and networking.

I have adapted the source to work only with OpenGL easily.

The original sources can find them in sourceforge.
