Abstract:
This paper presents a method for adaptive fracture propagation in thin sheets. A high-quality triangle mesh is dynamically structured to adaptively maintain detail wherever it is required by the simulation. These requirements include refining where cracks are likely to either start or advance. Refinement ensures that the stress distribution around the crack tip is well resolved, which is vital for creating highly detailed, realistic crack paths.
The dynamic meshing framework allows subsequent coarsening once areas are no longer likely to produce cracking. This coarsening allows efficient simulation by reducing the total number of active nodes and by preventing the formation of thin slivers around the crack path.
A local reprojection scheme and a substepping fracture process help to ensure stability and prevent a loss of plasticity during remeshing.
By including bending and stretching plasticity models, the method is able to simulate a large range of materials with very different fracture behaviors. - Наука та технологія

Cutting ducks is undesirable.
Now the duck is happy!
+Diogenes de Sinope :)
the larger sheet had some very impressive tearing skills.
juse came here for this xD
r/surrealmemes
Even by 2019's standards this is still extremely impressive.
I was actually thinking this was a 2019 vid till i saw this comment.
Malcolm Schmid I had to check the date on the video because I actually thought this was some new technology but nope.
Jordan Nolan and still not available anywhere to buy
except for the levitating ball and perfectly white background and the low poly edge of the frame holding the thin sheet
Malcolm Schmid same here
3:42, poor Sandy...

1:24 i couldnt tell the difference, surely the most realistic glass sim ive ever seen.
Please say your joking because that was real.
Lucas Broomfield lol no its not
Lucas Broomfield
Please say you're joking because that was a simulation.
Grace Perrone now that I think about it I think that was sarcasm
I was joking btw. It looked so real though...
Im glad the duck ended up ok in the end. I was losing sleep over that.
It's undesirable.
3:20 the bottom duck though
Now the duck is happy!
@@HeavySandvichGuy1 Yeah the bottom duck lost part of its beak :(
That was undesirable.
Now you are happy too!
1:24 You could have told me that was real footage and I'd be none the wiser.
That's not?!
jk i know
I thought the same thing when I saw it. Excellent work
Isn't it CGI?
@@dms1150 It is CGI, however, they're saying that they would believe anyone who said it wasn't because of how real it looks.
SAME!
0:58 I can tell this is supposed to represent foil and I LOVE how the tears bend slowly under gravity after being torn. Also the glass is gorgeous
If only audio could somehow match this with the same realism...
its getting there. watch Google's new video about their AI Synths! VERY cool stuff!
I still heard everything in my head
Relevant video: ua-cam.com/video/su6z9snjU-U/v-deo.html
I can hear the cracking in my head.
Man this Video is from 2014.., there didn't audio exists. Audio is fake., like you are.., and me.., and we all are fake..,
"Cutting ducks is undesirable" sounds like an odd but hilarious meme phrase.
Apart from that, yep, this is some great looking simulation stuff.
I've come back and watched this at least once a month since around 2015, and thought it would be rude of me not to leave a comment after all this time. Excellent paper, excellent presentation, absolutely gorgeous results.
Games are going to be so great in 10 years!

Maybe
Assuming you'd be able to purchase the stuff required to simulate this.
No. After 11 years since Crysis was released we do not have any revolutions in games. Will it be after another one iteration? Obviously NO. Mobile and console gamedev even dont try into techical revolutions and stay in stagnation. Because of strong hardware computing limitations.
I can watch these all day.
Hopefully one day virtual reality games will have lots of details like this
16 people still prefer voronoi fracturing
Unsound Methodist .
Lol voronoi is cool, but not very good for anything realistic
0:46 HERES JOHNNY In a ball version
**Begins to wield ball axe**
HERES BALLY
Another great tool that is not sold or used anywhere as always.
1:45 that's why I never buy glass Christmas bulbs.
that's why I always buy glass Christmas bulbs.
Lol
Wait, glass christmas balls are a thing?
@@Frisher1 yes, only recently people started to use plastic ones
@@GewelReal Well atleast in my country glass balls are non existant.
0:43 when spongbob realized he gets to work 24 hours
"Did you hear that squidward?, we can keep working and working without even having to go home, i must pinch myself because i must be dreaming"
This is some next level stuff, wow, well done !!!
I want to go 30 years into the future, steal a gaming PC, then go back in time and show it to 12-year-old me. My younger self would go from playing Doom to shitting his pants. I guess I'd also tell him how to not fuck up his life, but the first priority would definitely be blowing his/my mind with crazy as fuck video game graphics.
Please don't die.
Wow, this was uploaded in 2014.
Imagine where we're at today. 2019
I want this in Blender!
Yeah
They never made it public... And it seems they abandoned the project. That fucking sucks!
it's kinda in blender since there is a fracturing plugin
pretty sure you can do this with houdini,
Sweet dream. My imagination went too far...
wow this is some fantastic stuff! especially the pool ball hitting the glass looks very believable in slow motion
They just keep getting more and more real.
>"Now the duck is happy"
*me crying - "nice"
No ducks were hurt in the making of this film
except the one
7 years and its still not even thoughted about being implemented. Very sad to see great thing gets ignored. Amazing simulations!
The papers are public, you can implement the solvers yourself. We did back in 2016.
I like to watch this every now and then. Have for a few years now. It’s always neat
Anyone else "hear" the friction with everything? The metal, the glass, the wood, even the impact the ball made?
I can't be the only one who made their own sound effects with their mouth while watching?
ayyyy
i did
Yass
I hope you weren't trying to simulate the sound of breaking glass with your mouth. 0.0
*pop*
*pop*
I'm so exited for bullet-hole simulation as good as this!
All of these are really satisfying to watch
1:24 the simulation is great, but the glass material is even better. How did you make the glass look slightly green when viewed from the side of the shard? Normal glass BSDF shaders (at least in Blender) don't do that, and adding volume absorption doesn't quite get there
2019: eh let's recommend this
Still perhaps one of the most gorgeous physics simulations I have seen.
Probably the coolest video like this I've seen.
Five years passed... and I havent seen anything that looks close to a single of examples
UPD in games of course
These are some amazingly realistic simulations. Wonder how long it'll be before these are possible in real time?
They are now.
@@Dr.W.KruegerNot really, unless you throw a big chunk of GPU compute power at it - and even then probably not at anything much above 30-60fps
What a time to be alive!
I love watching videos like this.
1:25 actually indistinguishable from real life. Wow.
are these gonna be implemented into any 3D package? or even as a standalone software?
NEVER!
If it were distributed, people would use it to cut ducks.
And that's undesirable.
I find it cool how it automatically adds more detail to the parts where its needed
It's amazing how far we have advanced with simulation and graphics. Makes the trilogy of the Matrix seem more plausible.
No one:
UA-cam: *Adaptive Tearing and Cracking of Thin Sheets, SIGGRAPH 2014!*
Me: destroy all things!
0:46 so many jokes you can make with this one
Here's Johnny
We've been trying to reach you about your car's extended warranty
I could watch these all day
Wow, that is absolutely amazing.
You see stuff like this appear at siggraph all the time, but never a plugin, software, or tool to use for us, poor drooling people.
I wonder if you could mimic it
the project page for this has the source code
And? Is it a plugin that people that don't program can use? Nope. That fucking sucks.
@@jojolafrite90 If you can't code, what possible use could you ever have for this tech?
Surely though these projects stay in development for years, in hopes of bettering and eventually perfecting them
3:44 sandy: THEY DONE BUSTED MY DOME!
Squidward: They got pictures of me naked
Mr. Krabs: No one wants to see your moles
Someone: Eww
I've watched this video like 15 times now
It just keeps popping up in my recommended and I keep watching it
I'm starting to have problems believing this is simulated. It's so real it makes tears in my eyes. TuT
3:39 Sandy be like: AAAAAAAAAAAAAAAAAAAAAAAAAAA
Ball metal meteor
I wanna see these techniques among tools for game developers (in Unreal Engine, Unity) and 3D modellers (in Blender)!
Yes. But our planet sucks, so... NOPE. We have shit.
you can do this in blender
@@quasar1391 How??
Amazing progress
UA-cam is slowly bringing back to us the knowledge and technology we have lost to time...
I wanna know so badly how to make the simulation at 0:32!!
you get some college degrees, you spend years of research, a year at least to programming, then trial and error your way. i think
Grimtin10 You do not need any college degrees for this.
Just particle physics and 3D programming knowledge.
good point.
ths materials are made from tiny particles in that. When you optimize the relationships between particles, you can have any material. For example, loosen the forces and you'll get liquid. decrease elacticity and increase bonding forces and you'll get rock. etc
Start with blender it is free
Thats a big MESH to clean
im leaving.
i have watched this video dozens of times but i still come back to watch it every month or so
It be great to see this running in real-time.
0:13 Finals
PS 9 will get it.
GURken ikr
I would actually guess ps6, which is coming out 2025?
PC2
This is an impressive piece of fine work.
Wow this looks amazing!
That's a lotta damage
May Allah bless ...Tobias Pfaff, Rahul Narain, Juan Miguel de Joya, and James F. O'Brien For studying so hard.
WTF does Allah hae to do with a fucking physics simulation? Take your allah and his "prophet" and SHOVE THEM BOTH UP YOUR ASS!
Watching in 2021. Took half the video to realize this was a simulation. Impressive work.
every year these become more and more convincing
@1:25 that looks real, to me.
it is because of lightning
when can we get this on games?
Closest I've seen was The Force Unleashed back in 2007, they had amazing glass shattering and used it very few times in the game :/ They had metal bending, wood fracturing, it was awesome. I emailed the tech company behind it and it's supposedly used in Quantum Break and may be coming to more things again (it wasn't used after the force unleashed but was used in films)
But was force unleashed's fracturing prerendered animations or realtime simulations? Because I'd be very surprised if it were the latter all those years ago
This is the thing, I'm fairly sure they were the latter as well as the prior. Some of those simulations happened on the fly and it was amazing, back in 2007 too! I still think the tech is witchcraft... If you don't want to play the game and see the odd places it was used then you can see the tech demo with the small objects being thrown at the piece of wood, you can see it happening on the fly ;)
devices aren't ready for realistic physics (which already exist) as it requires a lot of processing power and would overwhelm most computers if it were added to games. Nvidia PhysX has been around for years and is far more primitive than what is shown in the video yet not many games use it as it lags on a lot of computers.
Many older computers maybe, even mine is lagging behind but I can run plenty of physx operations no problem. They used to have a dedicated card for physx but now it's done on the GPU and that's not a problem anymore. Nvidia Funhouse is a good example of this because it's doing it on a complex level but whilst rendering in VR. As I say though the DMM they were doing on the PS3 back in 07 was amazing
That is effin' great! Wonderful!
i love how that ball at the beginning has infinite force put into it's movement
How come those papers and simulations never end up as plugins for Blender. It seems those pieces of code are bought out immediately by big firms like Autodesk, or Next Limit. If it were some expensive plugin for Blender, I still could probably convince my employee to purchase one.
That is utterly damageable to the entire human race! Fucking pigs. That should be PUBLIC. FUCK! I'm so pissed right now. Yeah, big firms must buy the code. Assholes. Or at least it makes sense.

it is opensource, don't know about 5 years ago, but now is, however it is a pain in the ass because lmafo
our god is an awesome god
our god does'nt exsist

Это. Просто. Офигенно!
This is phenomenal
Slow mo guys retired
HA cutting ducks is undesirable.
Now the duck is happy!
Cool demonstration.
Unbelievable, great work from Great minds
Well done, very impressive!
Those are good simulations!
thats amazing how they can make things work like this.
Very nice! I wish I could learn how to simulate this kind of stuff. I've only messed with Blender fluid simulation a long time ago, but never made anything nearly as good as the other fluid sims people post.
Amazing!
man this look amazing
Inacreditável
the future of the physics in the games
Damn, this is sick!
this is so good it makes my stomach giggle.
That's incredible
The glass with the 8 ball was truly beautiful.
wow,,this is very impressive and very realistic
fantastic!
wow, this is so realistic!
Simply awesooome
Thanks, UA-cam algorithm for this gold at 4AM
God this is breathtaking
I thought this was done at least this year or last year, can't believe this was in 2014. Simulations have only gotten better since then.
I need more videos like this
