Wow. 4kb, and procedurally generated. Very cool stuff. :)

whats so special about it?

Daz April 16 2009 1:54 PM EDT

That is impressive.

Marlfox [Cult of the Valaraukar] April 16 2009 2:28 PM EDT

It's all made with math! And, it's 4kb big.

Lord Bob April 16 2009 2:55 PM EDT

Yeah, I'm impressed.

Goodfish April 16 2009 3:26 PM EDT

I don't get it. It's a boring video and a bad techno song?

Lord Bob April 16 2009 3:32 PM EDT

Yes, all compressed to 4kb.

Goodfish April 16 2009 3:35 PM EDT

I'm still not entirely sure why that's impressive. Honestly.

I know videos are generally larger file sizes than that, but... well, what does it mean?

iBananco [Blue Army] April 16 2009 3:36 PM EDT

Very impressive demo.

iBananco [Blue Army] April 16 2009 3:40 PM EDT

4KB is a ridiculously small filesize. If you encoded that to a video, it'd probably run around 4 orders of magnitude higher. Even rendering it from textures and a mesh would require significantly larger amounts of storage, not to mention a 3MB+, compressed audio track.

So how did they do it?

Marlfox [Cult of the Valaraukar] April 16 2009 4:05 PM EDT

Procedural generation.

QBOddBird April 16 2009 4:08 PM EDT

That's insane.

AdminTal Destra [Forge Of Norn] April 16 2009 4:11 PM EDT

so what the guys are attempting with this is to make all rendered items smaller?
that would be very awesome in say WoW-esque game..
make the download from 4 gigs to like 2 megabytes would be insane

iBananco [Blue Army] April 16 2009 4:23 PM EDT

It doesn't have very many practical purposes. Firstly, procedural generation is ridiculously hard to fine-tune. Secondly, it requires extensive computation to generate them on the fly, so often what is done is a precomputing stage where all objects in the scene are precomputed, then stored into memory. I'd personally prefer a onetime download to 5 minute load times.

Goodfish April 16 2009 4:50 PM EDT

So is the video itself the 4kb file, or is the program that generated the video 4kb?

The former would be completely absurd; the latter seems much more possible.

@ Goodfish,

The idea here is that all the imagery you are seeing is generated by a code base and data file totaling 4k.

If the video file was 4K you wouldn't even have a single frame a today's compression rates. As it is, the fact that one can get such detailed imagery out of a 4k data/instruction set is quite impressive.

Goodfish April 16 2009 8:03 PM EDT

Okay, that makes more sense to me. :) Thank you for clarifying!
