Hi, I'm attempting to do a responsive visual environment on my monitor using the viewers perspective to create the perception of 3D. Like Johnny Lee did in http://youtu.be/Jd3-eiid-Uw
but ill be using a Kinect for head tracking.
As you can see in the patch below, I'm pretty close. But my camera position is not correct. In practical terms, I need to set the origin of the 3D scene at the center of the screen and consider the screen frame’s dimensions as constant values. In this coordinate system, a virtual camera is set at the position of the user’s head, pointing towards the origin. As the user’s head moves, the parallax of the 3D scene is altered by varying the virtual camera’s field of view and its offset position. I'd love some help on this one!
