Oh yeah, I forgot about that. I wonder what this one's runtime in RAM is. Regarding GPU quote, that's exactly the sort of thing I'm talking about. It's sort of a cheat where a massive amount of resources are used in one place to reduce a tiny amount in another. An impressive optimization requires little to no extra resources in B when optimizing A. There's some types that straight-up can't seem to have that tradeoff.…

Programming is all about finding and exploiting ways to cheat. I remember overhearing a conversation in the Sun cafeteria about how the Aviator flight simulator only had one-half of a 3d model of the airplane, and it just reflected it to get the other half. They complained that was cheating, but that's just how it is!

Oh sure. It's one approach. We have to rate the cheats or honest work somehow. I think one way is to look at both what's produced with what type and number of resources are utilized. The constraints each provide plus what's achieved with them vs some baseline might be a good example. Baseline maybe determined after first round of submissions.

Btw, I'd probably have left off Space Invaders for exact reason you mentioned. Curious to know what you find to be most impressive demo on that system, though.

>Regarding GPU quote, that's exactly the sort of thing I'm talking about. It's sort of a cheat where a massive amount of resources are used in one place to reduce a tiny amount in another. Since the demo was originally entered in the 4K competition at the Breakpoint 2009 demo party, it had to run on the computer designated to run the competition's entries. So it's not like it could require an arbitrarily powerful GPU…

Fair enough. The spec requirements I'm mentioning would apply to people setting competition requirements more than the authors. The authors should of course work within the constraints for any particular competition. They can still try my challenge on the side. " Intel Core2Quad at 2.66GHz, 2GB of RAM, with a NVidia GeForce 295 GTX with 2x896MB of VRAM. " Double CPU and more GPU than what I'm writing this on but half…

That's the thing, though.... If this were an arbitrarily sized demo, I (and probably most people) would agree with you about the GPU stuff. But it's not arbitrarily sized, it's all in 4K. And it's from 2009.

Release info: http://www.pouet.net/prod.php?which=52938 Binary: https://files.scene.org/view/parties/2009/breakpoint09/in4k/... Video: https://www.youtube.com/watch?v=jB0vBmiTr6o Everything you see and hear is procedurally generated by the 4096 byte executable, in real time. It still blows my mind 7 years after release...

4KB using directx/opengl, very different from old time writing stuff directly in the video card.

new constraints though... you got a fit a couple of shaders in there too :)

also impressive: https://en.wikipedia.org/wiki/.kkrieger

Conspiracies 64kb demo from earlier this year is fantastic too. http://www.pouet.net/prod.php?which=67106 / https://www.youtube.com/watch?v=qRVTI2y0BBg

How in the heck did they do that in 64kb

That is mind blowing.

Leaves quivering on a branch, realistic flames, realistic humans!

The water wasn't quite right but still.

Back in the day demos were more impressive imo. A lot of them now use direct x or opengl. For the most part the stuff you see isn't written by hand anymore AFAIK, they just have programs to generate the actual demo. Basically they use modeling programs.

While true for large demos, the 4kb — perhaps even 64kb? — are still written very much by hand.

Lots of groups use demotools, including conspiracy for their 64k prods. Check out the moleman documentaries for lots of interesting scene info and lore! http://vakondok.com/index_en.html

4k + 300MB per other commenter. Lets not focus too much on one number without other.

Here's their release of how they made it as well. Super interesting read. It's shaders all the way down. http://www.iquilezles.org/www/material/function2009/function...

Ha, that's my exact comment from the related reddit thread. Kinda cool, I wonder how often that happens?
