so, a fast 4k from rgba... this is a bad sign I guess.

that was fast, thanks for the video, iq! :) Nice 4k, quite impressive visuals. The music is a bit boring though.

I guess what's inside this prod so I think it's technically impressive. But I'm feelling pretty bad saying that the final result feels quite numb.

I respect Iq and RGBA as a whole quite a lot, but my pig comes here.

The blur is really great. I hate to start seeing demos that don't run on my machine :(

kinda interesting to see firsthand how much brute force number crunching power is available in current graphics cards :)

anyway, this is *really* short, so piggy i guess ;)

Pushing limits..first rayracer on gfx card prod so thumbs up. You say in readme it doesnt work on nvidias (or imply it) but I got an x1600 ati and it doesnt work here either.

"first rayracer on gfx card prod so thumbs up"
er, certainly not. i've seen some gpu-based raytracer in an intro (64k i think) back when ps2.0 was new, and half of the "high-tech" shaders people are doing nowadays involve some sort of raytracing. and there's also stuff like this, for example.
added on the 2006-10-15 08:38:17 by ryg ryg
ryg, I know there is research, loads of it in fact, but isnt this the first _product_ to use raytracing on the gfx card? Raytracing mind, not raycasting.
added on the 2006-10-15 08:55:44 by auld auld
i'm really quite certain that there was some ps2.0 only raytracing intro (64k or 4k, don't remember) a few years back, but i don't remember the name - can anyone help?

that said, i know there's a snooker game that calculates exact intersection points+normals in the pixel shader to get nicer shading - again don't know the name, but it does get mentioned regularly on the directxdev ml when someone tries out perpixel lighting with spheres and wonders why they don't look perfectly round :)
added on the 2006-10-15 09:59:04 by ryg ryg
imo much more than enough for a 4k.

Hi, thanks for the comments. Some words about few points:

.raytracing in shaders 2.0. Indeed, raytracing could be done in ps2.0, I actually did it myself (its somewhere in my web page), but not with shadows and reflections since you run out of instructions, while in ps3.0 you don't. You could even get this working at 40 fps at 800x600 anway in pure software. The prod was just a kind of "my hello world" experiment with sh3.0.

.raytracing in a shader not new. Of course it´s not. Anyway, very few demos (if any at all) do innovate in anything (technically) when compared to the cg community out there. We are always lagging behind them, so in this case it just happend again. Still, raytracing of spheres/planes/colinders is a classic on the demoscene

.unfinished prod. yes, I know, I don't care, and I will not finalize it. This prod is just a fast 4k, I had fun during the four days I spent on it.

.about the motrion blur you see in the video. Please do not thumb this prod up just for the mblur. The realtime exe doen't have the blur. BUT the realtime intro runs arround 90 fps, and it very well captures the fast movements that are synchronized to the muzik, while the 30 fps of the divx were not a high enought sampling rate to capture that movement. So I added the mblur to the avi so you at least figure out that the spheres actually move.

Again, thanks for the thumbs up and piggies!

You forgot to put a text on the intro saying what you were doing, like.. 'Look! only 2 polys!', or something like that. As I knew what you were doing I was able to go to the orgos and let them read the readme before voting ;)
rulez added on the 2006-10-15 14:46:52 by mrdoob mrdoob

trace, the orgos read the readme files and we knew what iq was doing. Who didn't read it were the people that were voting.

watching this after the compo, noticed it has reflections from one object to another, which was subtle enough for the bigscreen not to notice it :)

trace, i vote, and i read all readme files :)

btw, this prod rules!!!! :) maybe a little switch to wireframe would be enough to show show many polys are drawn :P
rulez added on the 2006-10-16 10:14:09 by xphere xphere
wireframe? :) :) :) good one.

About raytracing in shaders; there is also "Fair play to the queen" by Candela that does shaders 3.0 raytracing on 3 metaballs.The shader is available in the data folder of the demo for anyone that wants to learn. For this prod you only have to use glIntercept of course.

JaK, we'll see. ANyway Fuzzion allready used the technique for their AO-in-4k.

Hi, apparently in x1600 graphics cards (and pressumably in x1400) the driver goes into software rendering mode. It's probably because of the amount of conditional branches in the driver (not really many, but well). I think ATI is hardcoding the two paths of a branch and then cmov()-ing or lerp()-ing the results, and that makes the shader huge. In my x1800 everything goes fine, probably because a bigger instruction count or because they have real branching capabilities in the x800 (??). It seems then to me that nvidia better supports the conditional branches.

I don't have a x1600 so I cannot start tuning the shader. I'm sorry...

bonzaj: yes, painting, putting the floor, the electricity... uf, this is going to be loong :(

doesnt do anything fancy for the technology that it requires. and i'd rather be able to actually watch it so here's your anti-hype thumb.

looking forward to gpu raytracing being used for something more. :)

Thumb up for the sync! Ran in software mode as i have a ps2 card, but the framerate was perfectly in time with the beat. Made it a lot more interesting than it would have been otherwise.

Always provide a bigger safe mode exe or stop using .com packers. NOT working on Win64.

Vista 64-bit (RC2) claims it's not a vaild Win32 application, hence I assumed .com or similar nasty tricks. Sorry. But this means that the packer is using behaviour that works by accident in XP/XP64, and is why I still think safemode exe should be included...
