• nvidia only - for glsl conformance (but texture still doesn't look right): "ns(t,2" -> "ns(vec2(t),2)" and "mix(c[0].xyz,fn," -> "mix(c[0].xyz,fn.xyz,"
  Looked kinda interesting on the screenshot but severly lacks in execution. 2nd part is veery slow btw. If music is good don't waste it ;)

• nvidia only, but works fine on ati after fixing the following glsl conformance error in the pixel shader:
  pow(gl_FragColor,3.) -> pow(gl_FragColor,vec4(3.))

• antdude: patience... depending on your cpu you'll have several minutes of compile time (after the little minute of music generation).

• demo Windows The Flow by znah
• Just white screen (ie depending on nvidia-only api) with music by vivaldi. Wonder how much beer it took to get it through the jury.. ;)
  And what ryg said.

• Gratz with the 1st place, now you must be obligated to do a fast final version :D
  The reflection difference is because I couldn't maintain the bug in the original - but "only" important change is getting rid of the single "ubershader" (which I ofcourse can't do for the whole intro by simple shader replacement).

• Both nvidia and ati takes a big hit on the scripting-branches themselves (in theory it should be worse on ati, as it limits instruction parrallism), while it seems ati also takes a hit on the amount of code inside the unused parts - i guess it has something to do with instruction fetch as the program is probably exceeding instruction cache by far. Original compiled code size is around 3400 ALU VLIWs (and ~400 CF) on rv770, and utiltization looks to be around 3-4 instructions per vliw, so it's more than 10k scalar instructions.. Also remember that functions are not called, but inlined, meaning that the mainloop includes the big evalution function 24(!) times (or 12 if AO loops are not unrolled).
  One simple thing you should fix is to have 2 evaluation functions, one for each object, as this reduces program size and therefore speeds up compilation drastically.
  But seriously this would have been several TIMES faster with shader composition and the cpu choosing the scenes.

• Nice flow, music and scenes but terrible slow, and an extremely long precalc. I can see that most of this is shader compilation time.
  
  I grabbed the shader and made a rendermonkey version of the intro for a little debuggin session :)
  I'm not sure why, but it seems like it's an incredible bad idea to do the scripting in the shader - apart from the insane compilation time, it really slows down the rendering. I tested at different frames, and it seems it's rendering 3-4 times faster when only the 2 needed scenes are in. Something fishy must be going up regarding that branching, or maybe the driver compiler/optimizer is just giving up and running some slow fallback version. Next step is testing with the shaderanalyzer..

• baah: sult (which means hunger in danish btw) is using the same letters (mirrored/rotated) as lns - that's the main reason, it takes a bit to model letters using distance functions ;)
