How would I rotate a view in degrees? I\'ve got the following code setting up my view... public class GLLayer extends GLSurfaceView implements SurfaceHolder.Callback,
I am currently coding a little AR-Game for myself on the iPhone 3GS ;-) I want to use the accelerometer & compass data for rotating my camera in opengl. The camera has a fixed position and can on
