New volumetric lighting demo

[Luminescent]

With a 9800pro, I get around 46 fps, with 6xAA & 16x quality aniso (on Cat 3.4 drivers).

Uhmm, how does this run on ATi boards?
14 fps on a FX 5800 running at 510/1010 :?

What resolution is that?
I'm getting 41fps in 1024x768 with 6xAA/16xAF.

whatever the default res is, no aa/af

If you have never changed your resolution settings in any demo, then that's 1024x768. Otherwise it's the last fullscreen resolution you set in any of my demos.

Sometimes I create my models and textures myself, but I generally suck as a modeller or texturer. For simple stuff like the gold bar in the Glow demo I can fix that myself, but for a little more complex stuff I prefer to just rip some free stuch from the web.
Sometimes, like in this demo, I use maps from games. This is the DM-Tutorial map from UT.

Where did you get the information on how to load an Unreal map? For my experiments I use Quake 3 maps with a PVS but I would also like to try it with Unreal maps because it contains portals. I always thought the specifications were a well kept secret...

Hmm, probably some nifty technical stuff in the demo, but the end result on screen is not that impressive. I remember my Voodoo2 doing a much better job at volumetric lighting in the original Unreal. Just my two cents.

Using UnrealEd you can export maps to a text format that's relatively easy to understand. From that you can convert it to your own format, if you like.

That's subjective of course. I agree that the volumetric lighting in Unreal definitely was great for it's time, but I don't think it's better. It is a per-vertex operation which sometimes made the volume move along triangle edges etc. as you moved around. It's cheap for a low-poly game like Unreal, and gives quite good results and really enhanced the mood in the game, though I would argue that the effect has more volume in my demo. IMHO of course.
