• 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 :(

• doens't work here. I have .net 2.0... is it because of my x64???

• I like the intro, especially the begining. It's also very short (well, not as much as mine of course), that's a pity.
  
  Funny thing, you say ATI drivers suck, and I normally have the opposite problem (nVidia drivers suck). Well, it still works fine in my ATI :)

• 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.

• thx trace.
  
  For the x1600 and x1400 owners. Anyone kind enough to test few exes drop me a mail to iquilezles at hotmail. Thx!

• 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!

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

• First MFX demo I like since "dose" - so, second mfx_??? entry in my hard disk.
  
  The framerate is not good (what f. filters do you use?) but the rendering is quite nice.

• By the way, Va2 makes a difference of 6kb in our last intro when compared to the kkcrunchy I was using before, and 5 kb when compared to kkcrunchy Va [so, > 16 kb when compared to upx, hehe]. Its also much MUCH faster to compress. Amazing!!
