the towel is sooo realistic btw we humans with our big brain can simulate things like towel twisted. it might look crazy but we do it using data learning i wonder if those algorithms do it with pure physics calcul or if they use memory (which is kinda overpowered as we can barely align multiplication while we can predict the behavior of flowing water)

[@lennartgimm]

So the research advances each month by what I'd predict for the next couple of years. This is astounding and I can't wait to see what advancements will be made next. It feels like soon there will be no problems left, other than making all of this real-time and building bigger and bigger scenes (although I know that isn't true, there is so much interesing work to be done, but you know, every video feels like this is it, we've reached the future). Greetings from Göttingen

[@rodrigoferreiramaciel4815]

I really liked that different format of video because we can see multiple advances in the technology industry in one single video, even though they aren't so detailed it's a cool thing :) I think it would be cool to the channel if it became like a 15 day-ish basis series, or even monthly, maybe they could be like some bigger-ish videos compared to the other more usual u do, I think it wouldn't even be a problem if it includes contents that you already talked about in specific videos 'cause some people don't have so much time to watch and it'd be a easier way to it keep up date! maybe it could turn into a "top 5 papers of march", Idk, think it could be great! although they probably need more time to be made I think it'd be worth, hope that idea get to u, love your content

This is mad bonkers the amount of detail that comes in the material displacement without mesh tangling! Also a few minutes per frame was much more reasonable than my original thoughts. Still a long cpu time, but hey, the results speak for themselves

[@Ben-rz9cf]

I am glad you are referencing houdini because it is important to show the comparison for what tools we already have implemented for artists and how much further the research has come. I always find myself with a sense of envy watching this channel because the simulation science evolves so fast but it actually gets implemented in the software so so slow. You keep saying 2 more papers down the line, and we see how far it comes in 1-2 years, but even after these things are demonstrated at siggraph it will be another 5-10 years before they become widespread with actual use. It makes me sad because we have such great researchers but not enough software developers who are familiar with these papers to work with them.

[@parchmentengineer8169]

I'm sorry, did you just say "Millions of contact events" and "A few minutes per frame" in the same paper? That's crazy impressive.

[@sagemeline]

Software engineer here. 776.2 seconds / 264k average 'contact events' == an average of 2.94ms per 'event.' This is insanely slow. and remember, this is on an 8 core 3.0ghz cpu. It should be churning through these several magnitudes faster than it is. Seriously, anything that takes even a faction of that much cpu time *per calculation* needs some serious attention. (This is sadly pretty common for academic code as in that field performance isn't even a criteria, let alone the primary one.) He said it would need to be re-implemented to run on a gpu, so this likely means it isn't tuned for parallel processing. Honestly, it likely isn't using multithreading at all, so we can assume it's running on a single core. (aside: good choice of Intel for this, as single-core is the only thing they do right). Best case, though, that's roughly 8.8 million cpu cycles for each contact calculation! (which only includes 1/264000th of the cycles for the full render code). And even if I'm wrong about the multithreading... that number only gets worse the better the code is at it. I am totally impressed by the dev(s) getting the simulation so perfect, though. It is a joy to watch. But to call its speed impressive? Just no. It needs some love and attention, including a serious refactor.
