Usage:
Mouse : Look around
w,s,a,d,q,e : Move around
Space : See the re-projected pixels
The algorithm raycasts only a fraction of pixels for each screen. Most are re-used from the previous frame exploiting frame-to-frame coherency, which allows a speed up of up to 4x. The algorithm is explained here: http://voxels.blogspot.com/2014/05/raycaster-speed-up-up-to-400-by-image.html.
