I have been developing a augmented reality 3D Racing Game. I'm planning on doing an AR application that will use GPS and Augmented Reality technologies to get a location, and then use compass/gyroscope for tracking 6DOF viewfinder movements. By merging the real world and the game world, augmented reality helps you discover a new way to play........Your racing track is populated with 3D interactive characters and scenarios.
But my question is how to use any vision processing(relying on GPS), and to display 3d models on the screen at roughly correct distances (up to a point) from where the car is positioning.
My target platform will be mobile devices & tablets potentially running one of these OS's WM6, Phone7, iOS and Android.
