Just got to do a few tiny tweaks to the 7th chapter covering the Strauss lighting model.
I'm hoping this chapter will generate some interest when published - the model is 17 years old already, but it became fashionable again courtesy of 3DMark06. From my initial research a few months ago a lot of people were asking about it (seemed to be the 3D fanboys rather than developer though) but there was very little if any information available. Strauss' paper is one of few that you have to pay to look at.
Strauss' model doesn't introduce anything new, rather it makes existing features much easier to use. Which I find amusing as the 3D fan-boys jumped all over it thinking it was some amazing new algorithm that automagically made everything look better [lol]
The bottom-right may well look incorrect, but bonus points to anyone who can tell me why it is in fact correct. Everyone else will just have to buy the book to find out [wink]
