He means by being able to get more intensity out of lights. Like what you see in those high dynamic range demos w/ the radeon 9700.
Quake 3 hacks this a bit to get a greater range. From 0 to 2 I think. Carmack said something about this in a plan, or was it an interview, well whatever. Really though, inorder to get lights that can be bright like you want and have a large range of intensity is to wait for the next gen hardware (9700 & NV30) with their floating point color for high dynamic range. Now you can hack it like Carmack did but it’s still not that great (and no were near the quality and range that the next gen hardware will give you). Actually i’m not even 100% on how to do that. I seem to remember a discussion on here that talked a bit about this.
I didn’t know that q3 did that. It looks like a basic game with great usage of multitexturing and a whole lot of animation of all sorts.
I don’t think that the high dynamic range trick is a good idea for games. It will make some parts look to dark, almost black since our eyes are not sensitive to low brighness colors. Its better for CGI.
or I would have to a game using it to see if I like it
