This is a very simple head-tracking using OpenCV and only Viola Jones’ face detection framework.
Basically the idea is to use face / head tracking to create an immersive 3D experience. This, is of course is still a very early prototype.
I whipped this up in less than an hour, so it’s very dirty and lack of any optimization. You can make the whole thing faster using CamShift algorithm, and some cleanup on the OpenGL codes.
Have fun !
