Not that good in the scenepoetry department, but I did like the fluid system smoke effect a lot.

What visy said. Good display of the one single effect, but the poetry....

Love the effect. Really beautiful.

First 8k I've ever thumbed up

I didn't like the poetry but the effect was really cool.

Nice smoke effect. Basic 2001 scene poetry.

too much text

Don't really care for scene poetry myself, but the reverse fluid dynamics effect was awesome.

Cool effect!

I can't really figure out how it works though - in theory, CFD is reversible, but because of numerical issues the fluid shouldn't be able to return to such an exact input shape. Did you use an implicit solver or is there some other way I don't see?

Either way, really nice end result!

The author actually had slides explaining how it works. I guess he could post them here.

Very neat. I can't even do smoke/liquid effects the normal way, let along backwards. Impressive (:

For the effect.

Great looking smoke effect, and a splendid idea with making it reverse to the texts.
Personally this would have made a much bigger impact on me with:

- better poetry
- better music!
- better placement/display (design?) of the texts. They feel awfully random, but yet not fully randomly placed

Great work

really loved the fluids or whatever it was--is. looked like they "played" backwards.
rulez added on the 2014-04-23 02:01:46 by rudi rudi
Nice. But with decent typography this would have been so much better...

Ahhh, so pretty!

I like technically impossible demos.

I love the effect and the idea but I think that it was wasted with overuse of inane texts instead of, for instance, use pictograms, or little graphics, or simply more interesting things than dull and forgetable text.

Motivational piggy.

What ham said, only with a weak thumb up for the original effect.

Great effect!
Too bad it was "wasted" on dull poetry and typography

Top notch coder tech porn. YES.

A pleasure to meet you at the party.

impossible! awesome concept and execution, but the typography could have been better to make it really great.

really great effect pulled off in a good way.
not so sure about the scene poetry but at least its done right!
music was ok-ish

what everybody already said, original effet but meh scene poetry, but -hei- it's good after all :)

hmm..it seems that i can't judge the smoke effect properly.
i find this really boring.

Yep, the inverse fluid dynamics effect puzzled me (even if I haven't ever coded one, it seemed at first that the reverse would not be easy without saving frames). Rest of the demo is kinda boring, but thumbs up for code.

Excellent effect and nice music.

Good idea, but a bit boring

one trick pony, but a fucking cool one

cool concept but I really wish there had been more sync etc

Thanks for the comments everyone! I didn't expect this intro to be very popular, because the difficulty in the effect is hard to appreciate if you haven't coded fluid dynamics yourself.

The basic technique is explained in my 4K seminar here: https://www.youtube.com/watch?v=DQ8eB_FORLo, with example code finally available here: http://www.fulcrum-demo.org/wp-content/uploads/2014/05/Reversing_Entropy_Seminar_by_Seven_Fulcrum.zip

To get it working with fluid dynamics, I had to modify the pipeline a lot to balance memory requirements, GPU power and pipeline length. But you can never get it working perfectly, unlike the fire/water examples in the seminar, so I had to hide some hiccups with creative choice of scenes. So, no actual reverse solver was used, Noobody :)

The content is minimalistic, because I only got the music a few days before the party, and for the longest time I didn't knew if it would fit in 4K or not. And when the music turned out not to fit in a 4K, there wasn't enough time to add bells and whistles to make it a full 8K...

Reverse fluid dynamics!
Very clever concept, ace execution, fitting music, deserved 2nd place!
I am happy i watched your seminar before watching the 8k! ;) It all made sense to me this way! :)
Must have been fun and hard to do this! Finally some NEW effect again!

nice demo to follow up on the great revision seminar with the same theme.
