This is the first 3D game engine that I created. It was created in 2007. It was created in C++ using DirectX 9, Havok Physics, and FMOD for sound. It is basically a tech demo with 3 scenes. First a little river bed with physicly simulated balls rolling down using havok physics. a terrain generated from a height map, and a floor with a guy that can walk around on it and up a ramp demonstrating the havok character controller.
