Very good. No ghost forces anywhere! 👻
I was confused. This is U+26D3, which according to Unicode is "chains", i.e. "tyre chains required", but it is rendered as whitespace in my browser. So, this post appeared as a very tall post of absolutely nothing…
@@Bisqwit Always refreshing to see another Linux user.
@@segfault- Linux user here, I see the chains just fine ;)
Can see the chains on ios
It's always a good day when a two minute papers video is published.
@@nagualdesign doesn't time go slowly when you're not having fun?
What a time to be alive!
Peppers? We don’t have peppers!
@@LevantWasTaken i dont think it has to do with fun but rather the way information gets delivered.. hearing information will always feel longer than if u actually do something but hey i might be wrong maybe he didnt pay attention and was looking at the clock then ofc its gonna feel long
Indeed it is my friend.
this et al guy is a genius, he's on every project
He's quite old now, but still going strong!
...and he gets around!
Lol
He must be a genius, perhaps even a super genius !
I'm not sure if this is a joke but the et al means others
The golf ball simulation is so accurate, absolutely amazing!
Every paper I'm more and more impressed
Same! It's gotten to a point where I'm already holding onto my papers before he warns us! :D
I agree, that was absolutely crazy!
@@1ucasvb Everything in this was incredible. I kept thinking the towel simulation would fail eventually due to the huge forces, but it just kept working...
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)
*Two minute paper uploads*
Me: What a time to be alive!
😂😂
This does put a smile in my face
He's just gonna say it in every video. I know it. 💯
soo original , never sow that comment...
idk man I'm dead inside
Day: bad
"Dear fellow scholars"
Day: gud

@@TwoMinutePapers Hey! you let go off your papers! don't do that
@@TwoMinutePapers praise the papers lol
@@TwoMinutePapers I LOVE THIS
What a time to be alive!
Imagine how crazy realistic game physics will be 5-10 years from now. Absolutely mind blowing.
Thinking about the same, implementing this in a game would surely be a game changer 😁😁
@nasolem maybe in games focusing on like dueling, where you could use for example chain based weapon
my pc still won't be able to run it.
@@scooby-dooafterlife6969 Physics covers a lot more than just chains.
@@dinkledankle I know, what ideas do you have in implementing realistic physics into games?
We: How many papers down the line we are close to live in the matrix?
Dr Károly: ⛓YES⛓.
Actually as the days pass, living in the Matrix becomes much more acceptable for me
Materials testing anyone?
"Praise the papers!" Love this quote
;)
How did you manage to reply before the video was submitted? 🤔
@@Klaster_1 I enjoy these videos so much I pay for Early Access.
Worth every penny.
@@ntwadumela_jadu9747 Thank you so much for your generous support! 🙏

Wow the twisting blew me away. I have no idea of the physics behind it but even just the fact that it retains its volume as it forms those extra knots is mindblowing
you missed saying:
"what a time to be alive" in this video.. 😐
Yes i was preparing myself to say it but i was triggered 🤣
no no that's for 2 papers down the line
we no longer alive, its all simulation now
@Wiktor Chojnacki What a time to praise the papers!
0:45 1st thought: ok, so the werewolf is anatomically correct, but maybe a bit exaggerated?... 2nd thought: oh, it's his tail...
The tendril test was super impressive!
Very excited to see these kinds of materials in video games one-day.
I don't even understand half of what's being said but I enjoy the enthusiasm.
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.
~500 years from now, inside one of these simulations: "dear fellow scholars"
Maybe we're already inside the simulation
@@martiddy how long do you think each frame of our simulated word takes to render?
@@emko333 According to modern physics, around a planck time unit
@@martiddy yea but that's our experience of time, each frame could take a billion years to render and we wouldn't notice i think.
@@emko333 good point
3:13 isn't a foam ball it's a real golf ball. A foam ball wouldn't have the momentum necessary to compress itself like that.
From the paper: "Top: we show key frames from a highspeed video capture of a foam practice ball fired at a fixed plate. "
@@TwoMinutePapers There is an old video out there (ua-cam.com/video/AkB81u5IM3I/v-deo.html). I think it shows exactly the same clip (look at the background, its the same). In the old video it is stated that a golf-ball was used. This may be a big conspiracy :D
I remember when Pixar animators were freaking out because they needed to have a character put their fingers through a tear in a piece of cloth.
That indeed used to be an extremely difficult task. What a time to be alive!
Praise the papers! Thanks so much for your brilliant way of communicating these sciences!
Now do it in real time in VR with raytracing !
How many papers down the line we betting? I'm betting 3.
Well... I wasn't able to hold onto my papers, I was so amazed by the advancement in only a few years that they went flying everywhere
Hello, I am just a French spectator with very little knowledges of computer graphics but I just wanted to congratulate you on your work and your popularization work. I find putting subtitles on every video extremely cool. Being very interested in SIGGRAPH, being able to have access to so many technical details on papers so little known to the general public is simply great! thank you very much !
40 years later:
Now hold on to your papers. With this new method, we can simulate our universes without dinosaurs. Loving it
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.
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.
@@sagemeline Thanks for the info! These are still some impressive simulations, but it's good to know that they can get even better with more effort put into them.
This is slowly becoming my favourite channel
When five minute papers upload five minutes ago u got to watch it.
heathen
its two minute papers
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
This is by far the most impressive paper I’ve ever seen featured on this channel. Absolutely amazing.
That tendril ball gives me a lot of nostalgia, I need to buy one of those for old times sake
Man, the first time I awe at the realism of these simulations. If they add on textures and do not tell me that they are cgs, I don't think I'm able to tell them apart anymore. Absolutely brilliant!
Now THIS, is epic.
Thank you so much for this video btw. Your content is absolutely great.
2:26 Finally I am thinking like the seasoned schollars 😁
the twisting test is amazing!
what a time to be alive!
All those complex interactions, computed accurately, using only a CPU, no GPU, and the simulation still manages just minutes per frame.
That’s insane.
❤️ love your videos everytime!
This. Is. AWESOME!
Praise the Papers! 🙌🏼
Funny how they are no longer 2 minutes long. Love them just the same 🙏😊
I'm a mechanical engineer, and have always kind of avoided programming, but your videos make me want to learn. Thank you for all the cool videos :)
Thx soo much for answering my question from the last video!!! (The one about how realistic these simulations are)
I love to see the development people make! This is sooo good!!
I can't wait to make a club sandwich with all this bread :D
I think UA-cam subscriptions needs something with higher priority than "Subscribed + Notification bell: All" for Two Minute Papers.
idont know im just a beginner, my opinion is that no matter how many times simulations can make the results to a real world the problem is only in air particles and gravity because the earth has a round shape then it also affects the real physics. it's the same as you do it in an space
but in all my opinion your guys work so impresive.
You're like cgi daily dose of internet. Keep it up!
This is super satisfying
And now imagine this kind of accuracy in physics accelerated as approximated AI/NN models that can easily run in real-time games on most modern gaming GPUs. I can't wait for the first games with proper physics like this, especially in VR; what a time to be alive
Wandb might be the best sponsor I know on UA-cam.
I remember doing that to rubber bands as a kid, if you get the knots to go along the whole length, it then does a new top of knot made out of the curled up knots
So now we've unlocked the ability of "the" Simulation to create accurate simulations within itself.
Next unlock feature of "the" Simulation: create accurate simulation of the big bang and life.
When I make my physics engine this channel is gonna be a diamond mine
Blender needs This!!
me watching the video: "of course, there's a lot you can do with a gpu"
Dr. Károly Zsolnai-Fehér: "...all this is performed on your processor..."
*Dolphin in Town by Kingo Hamada starts playing
and later: "... minutes per frame ..."
This is horribly unoptimized. It uses (776.2sec / avg 264k calcs) or an average of 2.94ms of cpu time per calculation on the cloth folding simulation! Holy crap that is slow.
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
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
Another Upload!
What a time to be alive!
This is absolutely amazing. Thank you for sharing all of the wonder information to us.
I like that you added this "hold on to your papers" icon at the top. If it was there from the beginning, i'm not a careful observer!
With the words of Anton Petrov; You are a Wonderful Person, Dr. Károly Zsolnai-Fehér.
Siiiick. Only 35 years left to see this implemented in an autodesk 3ds max update.
Wow! That is waaaay faster than I expected!
Your so wholesome, and still educational, I don't get how your videos can put me in a good mood.
My computer cant even handle the motion of a liquid going through a pipe and you guys are showing such crazy stuff.
I bet they did this on supercomputers.
Man, with those baking simulations we could end simulated world hunger!
Everytime you show us those great simulation I always wonder :
Where can we access those??
Impressive animations!
I'm wondering why the chains are made of rubber though. Metal chains stop abruptly at the end before swaying; they don't stretch and rebound like these did.
What a time to be alive!
4:46 What is even more fantastic, is you Károly. Your videos are really charming. I'm always looking forward to more science and technology breakthroughs with you.
The cloth twisting and the 4 elastic bands.. these were just super impressive! :o
Where can I get this tool which enable dictating mathematic formulas in natural language and as an output getting it in editable format? I mean the one you mentioned a few papers earlier. It would hugely speed my work.
I'm glad this channel exist because this is the coolest cutting edge stuff.
Loved seeing all the squishy things happen!!
I've become so numb to the phrase" hold on to your papers". I wish all these researchers a long, happy and healthy life!
The philosophy of two minuets paper:
what time to be alive
I think I said this under the previous related paper video, but this is amazing
Wow! That’s insane that there are never any self intersections especially in the twisting simulations I’m a 3D design engineer by profession so I can appreciate just how incredible that is!
i am totally impressed. unbelievable simulations. its amazing and frightening at the same time. that much correctness is a indication of the progresses of the softwares. and thinking the possible scenarios for what could be happen, and what human kind did with the technological advancements, it is terrifying.
I wish you could go into a little bit more detail about the differences between the new simulation methods and papers and their previous competitors. Great video!
Living in a simulation Confirmed
Stuff like this would be sick in a physics game like Garry's mod.
watching the CPU during the twisting tests:
*she can't take much more captain!*
Oml the future's going to be crazy once full dive becomes available. My only regret.
Praise the papers. 🙏
How hard/easy is for something like this to get implemented in blender? Would love to have real access to all of these amazing advancements!
This just opens up the possibilities of faking anything digitally
4:28 all of those crooked chains at the bottom, do all forces they'll enact on each other on a left-right basis equate to balanced forces????? incredible how the computer could predict it
Wow, the tendrils test 💯
Stuff like that tearing bread spoils me. These days can't look at films using mundane Voronoi fracturing for everything without shaking my head.
We are near to almost perfect Elastic simulations 😍♥️♥️
this can also be applied to replicating molecular structures ... if you need an actual replicator to do this in a more physical way, you could build a neural network "reality physics simulator" with an advanced artificial intelligence interface (another neural network) and ask it to generate a simple replicator device blueprint :)
Question, for somebody who is a professional in the field, do you think things like this will be possible in real time in the future? Will simulations like these ever be practical for games/entertainment?
thank you for researching for the future of jiggle physics to be used in things i love
I never feel more undeservedly honored than at the beginning of a TMP video.
I look forward to when it can be done in real time.
Looks real, a sense that we are approaching something on the horizon where it's all integrated... beautiful video especially the destruction of objects!
I nearly dropped my papers seeing the computer specifications!
a few papers down the line we might be able to simulate living cells. not in real time, because of the number of objects, but the physics interaction simulation are reaching a level of quick accuracy.
Could you make a video about how this simulation can be adapted to the molecular level? this would be a step in an interesting direction.
