Originally this was rendered for a video, but a few years ago, ATI licensed all the components of Pipe Dream and created a real-time version.
I tracked down a link on ATI's website for those who want to play the realtime demo.
It allows you to Pan - Zoom - and change viewing angles etc. Realtime demo link
It works on other cards too, I'm using nvidia cards and it runs nicely.
The original creators of this amazing vid can be found HERE. If you like the vid above you'll definately want to
visit their site as there's lots more like this.
Quite a few years ago, like 10+? one of our TV channels used to play these exact videos between shows or movies.
I can't recall if it was TV shows or movies or even what channel it was, but I remember it was a welcome break from commercials and it had the added
effect of capturing my attention and being a joy to watch.
