I was working on the positioning the camera object and the model. For awhile I thought there was a problem with the coordinate system I was using because no matter what I did I could not get the camera to go behind the object. Finally, I am able to get the camera behind the model object and as the model moves forward I can actually see the camera update behind the tank position. So I'm pretty happy with that now. I'm going to go ahead and now move onto integrating the physcis engine into the game. What I want to do is offload mostly all object movement and collision between objects into the physics engine (Newton: http://www.physicsengine.com) and then use the rendering engines built in primitives for other handles. Let's see how flexible the engine is in contrast to what I want it to do with the renderer.
