Other 3D Engines?

Hi,<br><br>I'm new to anything with the Pocket in front of it, but would like to start developing some simple 3D game for PocketPC. I'm not the kind of human being suitable for actually writing a new 3D engine, but I got enough experience with using existing engines (Allegro, Genesis3D, WT GameDriver) Are any 3D engines in development for PPC or is the Quake source most close to it? <br>
