Real Time 3D Fluid and Particle Simulation and Rendering

[granturismoMiguel]

Keiichi Tsuchiya: You Call that Drifting? :D

[ZizooMoDaI]

There was no wind in that simulation. Is that harder to compute, or did they just want to show off all the pretty swirliness that the wind would be blowing away?

[Fonix911]

what graphics cards were used to simulate this with? tesla/quadro or a geforce?

[kwoolfm]

@Fonix911 GTX285

[moozy1175]

where can i get that type of weed?

[flashcodec9999]

How many feet of a dustoid layer are you running over?

[KowaiTori]

that's quite the particle system, jeez.

[Omegaroth]

beautiful

[UnrealMan24]

Fake looking, but cool. Perhaps the car is made of... sand, and it's coming off the car. That's nice, better than anything I can do.

[TheXxmad4everxx]

Download link ?

[Rakvalde]

The driver must have been very high.

[DanFrederiksen]

I'd really like a virtual windtunnel app already. sucks that a good simple app doesn't exist

[arand4]

is it possible to have this as a "game" or simply is this project avaible for download and can you controll the car with your keyboard? and what program is that using?

[keer2010paris]

no way this is real time is it?

[SirithHeruwen]

@keer2010paris

The car anim is probably not(cus why bother programming an interactive vehicle, but i dunno.. cus you can see the wheels turning so quite possibly it may be..), but no doubt the dirt particles are real time. "We use a globally second-order accurate fluid simulation method which takes constant calculation time"

It's just that it requires some very powerful video card so it's unlikely a game would fully incorporate this at this moment since not everyone has the most powerful gpu.

[SlideR270295]

Where can i download this ?

[lbrieda]

did you publish a paper on this work?

[D4RK809]

WHERE CAN WE GET A COPY OF THIS??? WOULD BE LOTS OF FUN TO PLAY WITH.

[Pippomone]

A car in the desert!

[AdvHacker]

512 layers would be pretty roght for the graphics to render

[Blinkwing]

the particles simulate the air-movement. it would be a great way to increase realism in racing-games

[rockcabbage]

I want to play this... Now.

[Animaru12ify]

perfect thing to replace crappy dust clouds in video games!

[estebanrc88]

this is so SWEET!

[Alexandervo1]

That would look awesome in a desert!

[axelvdp1]

impresive!

I can run that with a GTX 460 ?

[91utuber]

awesome

[eugenealive]

Too bad these wonderful technologies aren't used by game developers. :( Damn consoles!

[sacredgeometry]

@eugenealive hardware isn't up to it just yet remember there are lots of things to render in games if you spend all of the processing power on one fx it wouldn't leave any for anything else. One day hopefully it will be because I cant wait to implement realtime particle fx.

r.e the video I cant wait till gfx card power is tapped into to improve render times in 3d software....its ridiculous that they are only just starting to implement it properly.

[eugenealive]

@sacredgeometry Right. But there already are several games where these technologies are successfully used without harming the performance. They are PC versions of Mirror's Edge, Batman: AA, Dark Void etc. (not so impressive like in this video but good enough).

But there are only 5 or 6 such games, and they are kinda exceptions. Most of games are multi-platform and developers just don't want to add advanced PhysX exclusively for PC versions :((

[sacredgeometry]

@eugenealive I agree, but performance drops hugely almost exponentially when you increase particles. I do a lot of particle based computer graphics I know how much pressure it can put on even the best computers. I dont think there are games out yet with realtime dynamic fluid/particals like this, I could be wrong as I build more games than play them these days.

[cavegames]

@eugenealive They certainly went in this direction, although today you'd still struggle to simulate more than a few thousand particles concurrently with running a complete game. PhysX was actually even more impressive back when it still belonged to AGEIA. Since NVIDIA bought it, they have been artificially capping the drivers to make the simulation slower, unless you buy a GeForce card, so much fewer people have the incentive to try it, let alone develop for it.

[TS0AF]

really cool simulation but would look odd in a racing game.

[jd18504]

OMG dirt 3 better support physx

[azjeff1971]

The Driver was named MARY JANE DOE

[pascbjumper2]

Where's the lagg?

[regemo]

I don't think they were cigarettes the driver was smoking...

[VJTProduction]

It looks like it's sand that is comming up, not smoke.

[alex911019]

some one in that car is so fucking high xD

[anysternon]

@alex911019 hora pior

[kuracodm]

does anyone know where to download this stuff.. so I can have some fun with PhysX

[blingdog15]

@kuracodm its not out yet :(

[CreativMediaStudio]

mkaaaaaaaaaaaayyyyyy

[AlanSessler]

the car is emitting sandstorms? ;)

[MrRodrigez]

@AlanSessler well, it is a 350z :P

[kautschukmedia]

NEVER EVER!

[Oatinator]

This looks like it would be a cool effect for a powerup in some kind of car game.

[fooffooffool]

fuck you

[blacksoul666guitar]

Looks like blender

[gman5807]

@DragonAge2k These games don't change because they do not support the PhysX card.

There will be new games coming out soon that will have support for it and will run really smooth with epic physics and graphics.

[realflow100]

well of course a gpu can have that many particles it don't have to calculate as much!

[zzxxcvbgfhyu]

это машина обожглась об видяху вот откуда дым ))))))))))))))

[mikeyrt16]

Very fucking cool

[krampster2]

animation heaven :) 

[xcaninox]

where can i download this to run in my pc ?

[yzbi]

This in gta iv and niko screaming "Little Jacob put that damn blunt out!"

[Blinkwing]

when the GPU's get more powerful, they can simulate wind-fluttering in video games.

[fulgore128]

street fighter 4 lol

[urmomisfineinbed]

should use that effect for a Bailey's ad rofl.

[Flybyhacker]

Long time ago ,to make this simulation ,the first thing come on your mind ,"SUPERCOMPUTER"

Today

Your mainstream(not all) Nvidia Graphic card can handle every thing

Anyone know where i can get this Simulation software ???

i just want to test on my GT 240

[Bru2712]

Real time? Holly crap man that's such the smoothest real time simulation I've ever seen!.

[TerminatorC28]

Hey nvidia ^^

I think you should make an interactive demo! That would be awesome!!!

[blobface007]

Thumbs up if you think that if it were blue not brown, it looks way more like water than smoke. If it were smoke, then there would have to be an atmospheric effect for it to collide with, these particle set on the ground

THUMBS UP FOR WATER!!!

[1998PloKoon]

I don't know what it is but it's awesome!

[Uploadification]

that guy in the car was me.............smoking a little JOINT

[JuniorProducer1996]

thats like in need for speed when the cars burn like hell and then go............still good :)

[nawaz2kx]

very nice indeed, but you would need an extremely fast nvidia card to render everything.. i gave up with nvidia cards ages ago, not worth the money.

[vrshowdown]

when will we see this in games ?

[B44rules]

@vrshowdown well, theoretically i think this can be done with the physx sdk and openCL...so i guess we just have to wait until the next racing, action, or space game to come out and we'll have desert rally racing and huge explosions galore. What's really cool is it looks to me like you could halve the number of cells and increase the visual size of the rendered particle, and you would have a lot more gpu free for other stuff without a decrease in the appearance for gaming purposes.

[peepzx]

where can i download this  plllllllllllease

[Blinkwing]

maybe u dont see it but it simulates the air being moved by the car.

It would be awesome for racing games!

[legmog]

Lol, well we only have to wait until Wednesday, March 25th 3005 :D .... Little under a thousand years :p, I can't wait :D

[ghhhks]

притормаживает xD

[imdbstar]

holy dog shit

how many months did you take to program this ? :D

[TheCreativeCoding]

Damn. Imagine programming that!

[AppleMacApp4U]

holy fuckin shit!

[Sheeraz20]

lol nice i had the background on my computer once at :56

[shadman1911]

reminds me of the smoke thing in "Lost"...nice

[innerguardianXIII]

now the smoke effect is Beautiful and i'd want it for my game....but if my car started giving off smoke as thick as that, i'd get out of the car and RUN FOR THE HILLS lol, Awesome effect, great video :)

[ClydeE247]

I don't know shit about Graphics cards right now, and I just have to ask - how would you rate an old GMA 950 (My graphics card LOL).

Right now I rate it a 2/10

[sergiozagato]

lucky i rate mine 0.01/10

[zombahkiller01]

lucky i rate mine at -1/10.

[ClydeE247]

@zombahkiller01

LOL, the worst part about mine is that it shuts down my CPU because it overheats, Very OFTEN

[zombahkiller01]

Worst part about mine, is that when i hit the power button, the computer wont turn off.

I mean it goes to the "Is shutting down" thing, but afterwords, doesnt change.

[lildragon5555]

@ClydeE247 check your CPU fan, it's usually a safety feature to shut down the computer if the CPU overheats to keep it from damaging.

[SkyGuyandSnips]

@ClydeE247 Happens to me too. So often as matter of fact that I murdered the mother board. Had to get a new PC.

[Poler777]

Is there a program for purchase that can do this. I'm not sure if furryball can do particle sims. Octane (GPU renderer) doesn't even do animation. Maybe you should sell this program, I would certainly pay a few thousand for it.

[6Debel6]

I can download this demo?

[rchoetzlein]

"i think this feature of the card was use in the movie like '2012' or 'Avatar' "

actually, its only for real-time such as games. runs on GTX285. for film, you need much higher quality simulations. Do google search for: "Interactive Fluid-Particle Simulation Using Translating Eulerian Grids", then look at pdf.

[Carbon657]

I thought this video was going to tell me what the real time is,my clocks wrong :-(

[Niklasdiver123]

how should that work?

[Carbon657]

Like clockwork

[DeceasedBubble1]

Aweesome! And...how many cigarettes was that driver smoking?!

[watt3256]

@DeceasedBubble1 more like Blunts!

[ror3dracer01]

@DeceasedBubble1 i dont think its cigerettes

[Stalkerdim]

@DeceasedBubble1 8-10 sigerettes blocks xD

[DevinTClark]

@DeceasedBubble1

Gentlemen

[Gannnjjjjjaaaaaaa]

@DeceasedBubble1 its called a joint

[SethiXzon]

@DeceasedBubble1 Enough to give him terminal cancer and fry his lungs into nonexistance.

[Dejayfever1]

@DeceasedBubble1 hahahahahahahahahahahahahahaha­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa­aaaa!!!!!!!! ddudududududududududdeeeee you made me laugh out loud!! ahahaha!!!

[wakeupfist]

Granted the hardware is quite capable but still, to come up with an approach that would sim and deliver chunks this thick, complete with shadowing and mblur in real time... you've got to be kidding me.

[666Azmodan666]

@wakeupfist

3ds max have blur in real time shadow to :] use DX9 or 10

[HannesGerl]

I`m doing vfx simulation for my living and to get this kind of movement in real time is quite amazing. Well Done!

[hihi2111]

Sure it looks amazing, but it doesn't look real in the very least. In terms of realism, I think Nvidia is going backwards, advertising so many things their cards are capable that can make the game look more flashy. We don't care for all this extra junk that is added on so you can make us buy your cards. ATI at least uses their ATI exclusive addons to make your games rock. Such as the ATInfinity and Stream processors that make the card faster. Cuz that's all we want a faster card. Right?

[computeranimationxll]

@hihi2111

this card is used for professional 3d graphic in vfx,

not games. the artist in film need real time simulation to create the most realistic and artistic effect they need as fast as possible. then take it to rendering with render farm.i think this feature of the card was use in the movie like "2012" or "Avatar"

[clubpenguin1help]

indeed

[hihi2111]

I don't know why everyone gave my comment a thumbs down I was just stating the truth, but I guess Nvidia fans are unwilling to accept this...

[ShrEadHunterN]

You failed to state the truth...

Yeah, in demos like these, Nvidia is focusing on "flashy stuff", to demonstrate how good their cards are.

When it comes to games, the developers either go with "flashy stuff" or realism.

The cards might be able to handle tons of particles. But still, some dev's choose realism over "flashy stuff".

There is a difference between show casing, and actually use it in games.

[darkargasio]

you have to google iray and vray rt cuda version..iray will be out really soon.....don't talk about things you don't know.

[dingo27mobile]

car doesn have a driver, who drives? K.I.T.T ? :)

[darkargasio]

WOOOOW this will blow up krakatoa particle render for 3ds max....the results are the same..but this is 100x times faster!!!!

[aegnt09]

thts so sweet!

[zaubertom]

WOW Does anyone have a downloadlink??

[rausmanxxx]

350 Z ?? my favourite

[sattanhellsing]

I do not read the comment of fanboy that know nothing about hardware and 3D software .

Me too blablablabla F#ck you too and merry Xmass !

[illmagnified]

@sattanhellsing Hey, i think you need to update your technology archives on parallel computing in your head, this technology has been around for years now and is finally becoming mainstream as it is now needed for a lot more apps and games as well as massive particle simulations done in real time because devs call for this. GPU's now have 1,600 processing cores and systems with 4 of these chips which is 6,400 cores all running in parallel are capable of not only this but far larger projects.

[xM4RC3Lx]

can I download it somewhere??

[sattanhellsing]

likely no , it is no real time . it is rendered by cpu and not gpu . what you see are a video and will never be real time . rendering take around 10 hours ...the finish will be a video . it is for this you will never find a download link for this stuff.

as fare as we can tell this video are a fake propaganda to make you believe Nvidia rocks wen actually it dosn't!

[xM4RC3Lx]

when this a Cpu rendered Test is, why is there an Nvidia-icon???

[cameron6697]

@sattanhellsing you must be real stupid...it is realtime, its done using a nvidia GPU with CUDA technology. this stuff is gonna be happening alot more now...

[H3Av3N2233]

@sattanhellsing You would know right?

[gevelegian]

@sattanhellsing Some people just wake up from sleeping under a rock for 10 years then start making "wise" comments! ;) My advice... STFU!

[Vire70]

@sattanhellsing You fail. CUDA is many many times faster than any CPU rendering around. I know because I've used it for things like rendering fractals.

[ShrEadHunterN]

It's fucking real time rendered.

What year are you from? And then saying "we" like *you* where a fucking professional?

How hard did you hit your head ten years ago?

CPU rendering sucks compared to GPU rendering.

Btw, your english sucked hard cock, so i think you just trolled from boredom. Which was a fucking bad idea.

[aamroo]

is it Simulate the air movement ??

[dessertmonkeyjk]

I admit this is impressive but the way it was applied in the demo looked like the car was literally on fire.

[TerracideDK]

Tech demos are not to show of bling-bling, but to demonstrate the underlying physcis...something you apperantly fail to graps.

[Blaze200038]

I can 'graps' that fine, thank ye' very much! But true, people need to realize that the idea of this isn't to present a realistic -looking- virtual environment, simply an environment that -behaves- realistically.

[TerracideDK]

So you admit your first post was flawed...fine.

[oisiaa]

The future of computing will be amazing. In 10 years time we should have enough computational power to have effects like this and water in a game environment.

[LuoSKr4D]

10 years is a bit too much..

[565Customz]

more like 2 i think

[Semezdar]

what 512 shadow lareys mean?

[wolfoe]

thats the resolution of the shadowmap. higher = greater.

[Semezdar]

man i wish i had physX card

[MongooseRoadkill]

Looks amazing.

[blip3452]

realistic or not, it's so pretty

[Ablequerq]

So? When will we gonna see this in a racing game?

[maitrelame2]

Probably 5-10 years, this is just research, not ready to be used in game, requires very specific hardware and very powerfull hardware.

[thecssnoobz]

more like 2 years.

[ShrEadHunterN]

@thecssnoobz

4 months have passed, and you now realised that it happened some months after you wrote the comment ;)

[ShrEadHunterN]

@maitrelame2

5-10 years? you gotta be kidding me.

10 Years ago, the 3D games you played looked like shit. 5 years ago, still shit.

Then suddenly, 2 years after, some of the games looked amazing.

And now you tell me that in 10 years we will see this in games?

There is an unwritten rule that says that all new hardware should be twice as good.

It usually goes like this: 2, 4, 8, 16, 32, 64, 128, 256, 512, 1024, 2048. You get the idea? It increases so fast that your little brain can't follow up.

[tjampe]

it's showing the air turbolence on the car, not dust

[videofxuniverse]

Looked unrealistic sorry but i havent seen any dustcloud like that being emitted from a car before not even in a frikkin sandstorm

[Kindahuge]

You're a silly little beaner : )

[Terabytekit]

do you at least know what turbulence is?

[darkargasio]

That was a particle rendering simulation,they didn't want to simulate dust.

[sobeita]

It's a simulation of the air itself, not tire smoke or anything like that. It's a visualization technique common in scientific demonstrations. In simulations of water, a dye with physical properties identical to the surrounding water is used to show currents which would be almost invisible otherwise; this is the same idea applied to gases (air turbulence with "rendered smoke".)

[davisorle]

Just read the title of the video. If you dont get it google the title's words and start learing or I dont see the reason you checked the video out :P

[chaOsMastaGuru]

pretty impressive.

[jhtrico1850]

The future is here!

[01DOGG01]

Yeah its a good pc. Good luck with your disease.

[GargantulaKon]

By the way is this supposed to be tire smoke? Check out my video of me doing the same things as in this video.

[Adanos]

i think this isnt supposed to be smoke, more like a kind of lieght dust... cause then it would look great ;)

[BurnerPat]

this is no smoke, read the describtion: "In this demo our solver is used to simulate the turbulent wake behind a car"

[GargantulaKon]

Umm, I did and he said, "we render smoke transported". He mentioned smoke so that is why I was confused.

[scienceminded]

"and we render smoke transported through that wake with a hardware-based volume renderer"

Way to shoot yourself in the foot by quoting out of context. It is both smoke and smoke moved by simulated airflow.

[Kindahuge]

They're not saying it IS rendered smoke, but that it demonstrates visibly how their airflow patterning works for better smoke effects in future games.

[scienceminded]

By definition, yes, they say they "render smoke" that is THEIR definition, ok, I'm done nit-picking now...I had to correct someone for correcting someone incorrectly....lolwut.

[R4Zy3L]

I think this smoke looks pretty good.

/watch?v=s10Zu7C4Q9s

[vectoranime123]

can this job be done with NVIDIA Quadro FX 580 please i need the answer

[virokill132]

i want . where do i get . thanks

[Mamoruanime]

Well no, it does matter how many particles you have... Each one in scope has to run through its own loop, and then be rendered on screen. If you have thousands of these there's slowdown due to the sheer fact it needs to calculate life, motion, and other variables over and over again for EACH particle. Imagine having half a million of these things cycling. Very taxing.

[technochook]

imagine!! Colin Mcrae dirt with this!!

[tyab87]

IT'S OVER 500,000 PARTICLES!!!!

[ravensharpless]

IT'S OVER 9000!!!!!!

[iankaufman80]

beautiful, just beutiful!

[Queeksm]

OMG.

[crazymanny00]

holy smother!

[crazymanny00]

im pro

[tiberiandusk]

how long till they can have multiple sims going at once? one for the tire burnouts, one for the dust on the roads, one for the smoke and steam coming from engines, fires, explosions? the future is going to be awesome.
