I like the one where it sticks to the jello. Looks more physically real
But it sticks because of a bug, not because the jello was actually programmed to be sticky.
@@AiuFFS oh i see. thanks for the info
@@AiuFFS even non-gluey non-sticky jelly still is sticky to dry tiny stuff like this, just like powder would fully stick to it, it has water in it . It looks still far more correct, it's not a bug, it's a feature!
@@AiuFFS well even if it wasn’t sticky the sand should still stay on top and it shouldn’t just keep bouncing for infinity until it slips off, jello isn’t even bouncy?
This will work real time for games in like a year or two
I'm gonna go with 5+ years

With improved computing technology, technology and simulation like this could allow for hyper realistic video games, and even extreme vr, similar to the plotline of the original SAO anime (I watched it as a kid but this instantly reminded me of that). While video games have realistic effects, they are pre scripted and not perfect to the situation, this would allow on the spot realism.
2:12
You’re telling me some people think dittos in a pool of sprinkles _isn’t_ useful?!
would the sprinkles stick to ditto or would they bounce off?
what is the consistency of ditto?
Omnical i would imagine dittos consistency changes, but in its natural form probably like a...jelloey squishy feel.
i love how everyone didn't searched for this but accepted
2:19 took me a second to realize those were dittios
2:10 pretty sure those are falling dittos
I was expecting to see some black doted eyes on them.

2:29 But what if the jelly is sticky? Some sand should stick to the jelly?
That’s what I was thinking the entire time lol
I was looking for this comment. It's so weird because their method looks less realistic lol
That shouldn't be so hard to implement, but i don't think it's what they were trying to simulate.
In the first method, this was an unintended side-effect, which they were able to avoid with the second method.
@@matthiasmetelka5296 yup gotcha
But the jelly in this sim doesn't have a sticky attribute. Just a bouncy and jiggly attribute. So nothing should stick to it. It isn't real jelly
I'll be impressed when they can simulate the bounces of a screw on carpet so you can work out where it's gone when you drop it from 10 cm and it ends up 5 metres away from you.
The last time something like this happened to me, the dropped item managed to end up behind me, with the direct path from where it started being blocked by my body and legs. How can this happen?!!!! It took about twenty minutes to find even though I saw it most of the way straight down to the floor.
The screw is a paid actor. I think physics is just an illusion.
Basically anything small I ever dropped on the ground without directly observing it did this. More often than not, it ended up lodged in the chair wheels too.
Derp, everyone knows it is the goblins tricking us, it is not about physics.
Large rectangular magnet on the end of a sweeping brush does the trick. I have found many lost screws that way but zero lost springs, I think springs have the ability to cross dimensions when first released from an enclosure.
2:57 I don't get it, I think that MPM handles the simulation more realistic since jello is sticky and makes the particles stick to it, while the right one acts like a hard surface like plastic despite being very flexible and the particles just bounce off of it...
Apparently it wasn't supposed to, so the second one was better in that way. Though I agree that it would make more sense for it to stick.

The revolution just began. Give it 10-15 years and it might be possible to simulate instantly. This is not an unrealistic though, and far from science-fiction.

Me: *same*

I actually prefer the jellow and the particles sticking to it as if the jellow is actually of a sticky substance. In the right showcase, they jump around way too much and unrealistically.
i agree with you
seems like both papers need a lot of progress in order to look realistic
yeah its like a hydrophobic jello or something. maybe the articles are supposed to be fluid though and its confusing because they look like sand.
I think the point is simulating the one property of the material (the bounciness) accurately without worrying about other things like stickiness. This is a demonstration, not an actual application.
@@henryambrose8607 ooooh i get it now , thank you
Yeah, it looks nicer, but if the original purpose of the simulation was that they should not stick, then the one on the right might be better moving forward
The simulations look like I'm shopping for ultra 4K TV's

This was the most eye-candy filled episode of Two Minute Papers I have ever seen. All of those simulations were absolutely incredible to see one after the other, despite having seen most of them already in past episodes of yours. Movies will never be the same! Video games will have to wait maybe two more papers down the line. ;) Thanks for sharing all of this beauty with us! :)
At the 3:30 mark it became John Candy filled.
Really wish computing power was good enough for this to be in games. Guess I'll have to wait till the year 2100
@@Nehji_Hann With it now being possible to ray-trace in realtime we are getting close to photorealism and true physics in games. It still amazes me that single images that once took hours to render can now be rendered up to 100 times each second in modern games.

**makes fat people's flabby arms jiggle**

2:07 ar these dittos
Yes
In the future, about 10 years, we will have this, the muscle simulation and the water simulation video all in one program, and unreal engine 10 will evolve from unreal engine to Real engine 1.
Particles would stick to jello, though. Is this really a mistake? This seems physically accurate to me.
yep
ophello the thing is that it isn't supposed to simulate the stickiness of jello, only the bounciness, that's why its considered an error
They mean jelly with only its elastic properties.
It only simulates how bouncy jello is
You can remove sugar to make it not sticky. Thats what they were going for
That hair animation, especially with the snow, looks absolutely phenomenal.
I love every one of these videos, don’t understand ANY of the technical discussion but still, fascinating! What a time to be alive!
watching 1:07 - 1:28 gave me the feeling of watching something as a kid.
strange feeling but made me happy and smile. thanks.
4:41 His computer has 128gb of RAM...?!!
Edit: Hilarious afterthought, In 5 years our smartphones might have more as standard.
That's not actually that much RAM TBQH, not for these applications.
Windows 10 professional supports 2TB of ram.
its more probably that we change our method to size than have phones that still working with gb, mb etc.
wait after 2 decades it will be possible to have 1PB of ram
btw if you didn't know a petabyte (PB) is 1024 terabyte (TB)

@@islilyyagirl up until a few months ago when I got my beast computer this was the case for anything more graphically intensive than a flash game. also I love your PFP
2:50
But the one on the left seems more realistic to me. Sand _would_ get stuck on a moist Jell-O-like surface and it wouldn't keep bouncing around. Am I missing something here?
i love the little dittos at 2:10
It is interesting that computer scientist judges “physical” as “ glorious and I think so”. Not from math and governing equations.
Wouldn't some particles get stuck on jello the more sticky it becomes? (ie when it melts slightly)
Yeah most of the jellos are sticky at some level even without melting but I think it was an unwanted thing in this case. It would be nice to add a parameter for stickiness.
The issue is that it's not a feature, everything would stick that much by default. With this method there's at least the option to make surfaces sticky if it's wanted.
I think calling it jello is misleading. It's just a translucent block that jiggles similarly to jello, but other properties like its wetness and stickiness are not meant to be part of the simulation.
then it should be called jigglo
really impressive, I'd like to voice my appreciation for your channel
Your shaders are masterfully written, and your finite element method is on point.
But the black sphere with hair is oddly attractive.

It's Really Awesome To Learn Here On UA-cam.
I like how barely any of the videos on this channel are two minutes or under lol, just too much interesting info to fit into that timeframe
Personally I like the original method as when you showed the jello, the one of the right looked way more unrealistic due to the prolonged bouncing
@-Jampex- That's the thing though - it is perfectly possible to design materials that allow 'adhesion' and don't bounce like that, but that's not the point of the simulation. If you look at the hair simulation, the point is a lot clearer - the hair on the left gets stuck, clumps and knots up, just by doing a flip. Imagine living with hair like that! It's a bug in the simulation, when an interaction like that should be set and not part of the method itself.

I feel likes it’s more realistic is the glitter stuck to the jelly, if realism is what your going for

3:40 on the bottom you can see footage of me after self isolating snack marathon for so long.
2:13 that one near the right looks like a ditto
they're all dittos
tbh I like the one where the particles stick to the jelly better, because jello is kinda wet anyway so I would expect any small little particles to stick. it makes it look more appetizing if it's supposed to represent food (like sprinkles)
