Real-world cloth exhibits complex behaviors when it contacts deformable bodies. In this paper, we study how to improve the simulation of cloth-body interactions from three perspectives: collision, friction, and air pressure. We propose an efficient and robust algorithm to detect the collisions between cloth and deformable bodies, using the surface traversal technique. We develop a friction measurement device and we use it to capture frictional data from real-world experiments. The derived friction model can realistically handle complex friction properties of cloth, including anisotropy and nonlinearity. To produce pressure effects caused by the air between cloth and deformable bodies, we define an air mass field on the cloth layer and we use real-world air permeability data to animate it over time. Our results demonstrate the efficiency and accuracy of our system in simulating objects with a three-layer structure (i.e., a cloth layer, an air layer, and an inner body layer), such as pillows, comforters, down jackets, and stuffed toys.

Inconceivable realism! Incredible detail and accuracy. They must have taken 3 months to render this.
Omg, there are graphics/physics demo's that solve nearly every problem you could think of, water simulation, cloth, destruction, particle, weather, facial animation/deformation, body physics etc. The list goes on; and I'm still waiting for the day when there is enough computational power to house all of these technologies and have them put into one huge game .
A game like that would not be computed / processed on your own computer, but would rather be streamed from a central render farm to your screen.
What we need for this is not computational power, but internet bandwidth and low ping, which costs far less.

That would be easier Nvidea are doing something similar already when rendering CGI for films.
Devo Castler Regardless of how it's done I can't wait until it's affordable for the masses.
Hector Maddock-Greene
Agreed

Why? You have been so conditioned to WANT things that you would rather suffer wallet hardships from the cost, have a huge PC that could be stolen or damaged and then having to upgrade every few years, than see MUCH BETTER games whilst also removing the need for a huge PC in your house, having the capabilities completely vamp up every year through IN HOUSE upgrades on their end, rather than imposing those upgrades onto consumers, having games increase 2fold every year instead of every console generation, whilst only having a sub model for payment for example....Imagine if all you needed was a little device plugged into the wall with your peripherals and you stream EVERYTHING including your OS. Hardware is becoming the past...don't get attached to it.
Someday computers will be powerful enough for this to be in video games
i pur it in my video games I made on my mac
I think I'm obsessed with these physics technologies
This is so great, I think software like this is going to be used not only to create graphics, but to beggin constructing the fabric of Virtual Realities.
There will come a day, sooner than you think when you are interactng with fabrics even more realistic than this inside of a virtual reality.
+James Mulligan the only problem is systems such as this can be quite expensive to run in real time. But if the great minds behind this research paper can run this in real time then yes vr with real interaction of fabrics shall happen.
This may be the best cloth simulation to date.
Thanks! We use Maya for rendering. We have our own codebase for simulation and we will release it soon (hopefully in summer).

просто кайф, аж тащился пока смотрел, такое удовольствие получил)
are the simulations running in slow motion? Everything seems very floaty
everything cgi has this feeling.
It's incredibly hard to simulate weight. Watch cgi films, cgi rocks and such feel very floaty too.
not only floaty, but CGI cloth always seems like it's made of some kind of plastic.
But that will change... look up the siggraph video on thin sheet fractures, that is the best simulation i ever saw
LongJohn Vllasaliu that's up to the visual aspect. Thats easier to fix than the "floatiness" of its movement.
I like how we can now simulate Teddie bears quite well, we are actually making great advancements in Teddie bear technology!
Great now computers can make the bed better than I can
i didnt think seeing three pillows drop could ever be that interesting to watch
This is amazing work.
How long does an average simulation like this take?
Awesome!! your work has lot of applications in fabric industry and maybe for an earthquake simulator
Sure, the simulation itself takes plenty of computational power, but how about its results? Could a real time rendered cutscenes take advantage of precalculated behavior of fabric (or really, any simulateable element)?
great effects, what software/plugin has been used?
WOW, stunning :O That's so amazing :) *favorited*
It's a cool simulation, but some of the cloth is not stiff enough, for example the jacket at the end behaves almost as if it's made out of silk sheets.
+vodkacannon the algorithm works, that's what matters. configuring stiffness to match specific cloth type is no problem at all
This is incredible!
2:05 is not quite realistically because the wind goes through the pillow. Acceleration must be the same inside and outside the pillow without involvement of the wind. But it was awesome anyway)
Sorry for my bad English in advance)
Why not use this in games for ps4, for example ???
Will you release sources too, so people can port it to softwares like blender?
good job this is amazing
i wonder when this will be possible to do in video games
2018 Still watched :)
cloths render with Vray or mental ray?
The down vest is too springy
It needs to be both more plastic and less stretchy
wow this is really being integrated in tp6 nice nice
my pc just exploded with this video :O
can i see the code of this for learning purpose?
When we'll be seeing this in games???
Not this century. PCs are not powerful enough to take a game using realistic physics..
Michael John Hum...That's a HUGE exaggeration...Maybe you should have said: "Not this decade",because technology is advancing quickly as hell.
Yes. :)
Decade was the word I was searching for.
Michael John LOL...Don't worry pal...Sometimes I exaggerate things too!!
Michael John By the end of the CENTURY we may be playing videogames (If they'll still be called like that) with mini-microships implanted in our brains or we could even teleport to inside a game world considering how freaking FAST technology is moving!!...The Matrix will be "old stuff".
But can the simulator computer run crisis?
Can't wait for virtual reality, were you will actually wear these things
Great job
1 or 2 minutes per frame, so a few hours per clip I would say.
amazing
are u people developing the matrix or what
another paper that will never see a commercial usage. Where is it? Where can i buy it?
1 thousandth like yo!
Happy Birthday 1:15
1:12 - hm , What is it....I know , this is a iphone...
2:50 it's Howard the alien
That's not Elsa
Can you simulate pillows battle between girls?
Not sure whether to be creeper out or not
the Vest is realistic
2:43 handycap
bouncy
Coming soon 2025.
Howow
ohio state for da win
go bucks!
02:39 me when young thug comes on
ohio!
go ohio
