It took a bit longer than I had originally planned, but now the 3Dc demo I promised is finally here. Haven't had much time to dedicate to this project, and unfortunately I had to do some changes to my framework to get things up and running the way I wanted it. I rewrote my whole DXT decompression code and added 3Dc decompression to it. I also had to write that 3DcGenerator tool (which I btw now have updated to include some more advanced normal map generation code) to get my 3Dc textures. With that done however, getting 3Dc into future applications will be a quick and easy task.

Anyway, this demo mainly shows off 3Dc texture compression and how to use it, but also illustrates how to use detail normal mapping. Plus a bunch of other stuff like offset mapping, cubic shadow mapping etc., but I've done that before.

Thank you humus! Can any X800 users try this? And note the performance enhancement moving to the compressed mode?

Well I did some quick basic testing running it in full screen mode at 1600x1200 and I was seeing about a 15% or so performance difference when switching between compressed and non-compressed modes on my X800XT.

I will, I'm downloading 3dmark03 right now, gonna run some benches on that, then I do this....

ok, heres my results, was the demo supposed to stop at some point ? becasue I tihnk it just endlessly loops...

jep, Humus' demos always have endless loop. They are not benchmark demo but rather tech demos.

I saw a major performance increase when running 3dc. On an x800 pro it was around a 15-20% jump in performance. :drooling:
