History
After finalizing the Tunnel Effect, I wanted to go for something a little bit harder and I came across this fantastic text by BlackAxe / KoLOr (1997).
Seriously, this paper is so well written that I have nothing to add. Only that I learned the golden rule in computer graphic:
Perception is reality..
Using raytracing technique, you can get a "Free direction Tunnel effect", much more sophiticated than the first Tunnel. The only hard part to understand (and I guess it was intentional) is when it comes to "interpolation", which is the essence of the trick.
First implementation
If you follow the procedure described you get a raytraced Free direction Tunnel.....running at 7 frames per secondes: You can check it out Here.
Beautiful but slow.
