My copy of Real-Time Rendering 3rd Edition arrived today, and from what I've read so far, it is awesome!
The whole book is printed on glossy paper with colour pictures throughout and I got it at a steal from Amazon UK (pre-ordered it for only £35 ...it has since gone up to £52!). Even at the new price it is still a bargain though
Now I can finally retire my copy of RTR 2nd Edition to a bookshelf instead of sitting proudly on my desk.
