Nvidia's physics Fluid Demo

[UKMinecraftTutorials]

they should put physics in minecraft

[Facefuckful]

I uploaded this video 3 years ago i didn't think anyone was going to watch it thanks for your comments the music is Aphex Twin :-) Three GTX280's was rendering this crazy since looking at the next Kepler cards are going to piss all over these! Oh well...

[Wandplank12]

this is sooooo 2008 XD

[rhun664]

you guys know that nvidia purposely built physx so that it would be hindered if run with cpus or amd gpus right?

reply if you want the link for proof

[MrShadowbquick]

where can u get this fluid sim at?

[Idkfawin32]

This sounds like Aphex Twin, or Autechre

[MrLucasGAN]

Im watching this in 2050 and this graphics sucks

[94Lorenz]

@haxbox7 they don't use cpu's! they are using GPU's!!!!

[TEKsterful]

@94Lorenz Physics = CPU

[TheTwistedbeaver]

@TEKsterful PHYSX = GPU, thats the point, why do you think its an NVIDIA example?, essentially Anyone with a CUDA gpu could run this

@keysle , as far as games go, theres just too much to do on top of the simulation, if people didn't care about graphics they probably could, but would you wanna play a game with awesome-cool liquid physics but graphical fidelity of Minecraft? not likely.

saying that, theres only about 61k particles, thats not a crazy-high amount

[keysle]

what's the reason we don't see these fluid physics in vames?

[XcrazyX10]

@keysle So much more in a game to render no computer would handle these water physics. Maby in a few years :P

[keysle]

@XcrazyX10 the creators of awesome battle said tomorrow.

[gmxgamer]

@keysle becuz game developers are ALL GAYS

[migiesmith]

@keysle many pc's couldn't handle them (thats what im guessing anyway)

[xrayfishx]

@keysle because you're not playing Just Cause 2.

And also because having GPU simulate water means you have to cut down on graphics and good graphics is what game developers believe in too much.

[haxbox7]

@keysle You could not imagine the ammount of CPU they need.

[Ricochet8844]

@keysle Please define "vames"

[Randomstation]

@keysle takes to long to render

[ectobuilder]

@keysle vames! lol

[xalener]

@keysle

Well there's little volumes like in these demos that run okay, and then there's a game that would require a much higher amount of detail and a larger volume of fluid than shown. This stuff is all just demonstrations of what /could/ be. It's not practical.

That being said, the closest thing to a game that uses this is Cryostasis, and MAYBE portal 2 if you really want to stretch it.

[snook5555]

@keysle I'd also like to add that with any dynamic object it can behave in unwanted ways that can harm gameplay. The more complex the simulation the more you need to watch how it interacts with gameplay. I have seen an unreleased 2d platformer using similar water physics on a GPU at GCAP 2011 Conference in Australia so it can be done but it can add a lot of extra time in testing and debugging depending on the game and therefore increase cost.

[HeroicHereticsHH3]

@keysle Only 1/10th of the game consumers' PC can run it. And as much as you think Xbox/PS3s "cannot lag" this would murder there processors.

[HaraldX123]

@keysle What you see in these demos pretty much show nothing but the fluid physics and a basic world model. In games it gets complicated - You need a detailed world, the PhysX, shaders, characters and other stuff that eats up the power of both - GPU and CPU. To run a detailed game with these fluids you would need hell of a computer (consoles would die in a corner as always). Another option is game developers just don't want. PhysX fluids have been intergrated in Cryotasis, by the way. :P

[oliveranation]

@keysle i thought that it was because its too expensive

[Narudude360]

@keysle Most computers can't handle the power it requires to process complex liquid forms. Consoles don't even stand a chance.

[samljer]

@keysle because as long as people will continue to buy garbage games like modern warfare en masse, the new stuff will never be more then just tech demos.

and dont kid yourself fanboys, the FPS genre has been 1 giant remake for the past few years, ESPECIALLY the modern warfare garbage.

[TheGagunga]

Looks at video thinks to myself OMFG I WANT THAT !. downloads demo.....

*computer crashes* D:

[dzpisx]

Hahaha we actually have computers that can do this real time omgosh

[fataxe1]

my graphics card just committed suicide because it could never do this in a million years....

[15firekid]

the music is crazy what is it

[TheFailureFish]

WTF FATLADY?

[TheFailureFish]

music was weird

[dasKeks28]

Without Hardware? Haha :D

I think u mean without gpu physics calculation.

[FulGore12195]

ATI has nothing on you, nVidia!

[al3x68]

muy util a fukujhima.

[def4d]

2:16 :|

[CORRUPT3Dmind]

@def4d Me Gusta.

[capatais777]

put on crysis 2 pls nvidia

[minotarr]

Jeez, was that in real time?!! Amazing.

[GroogFish]

I don't understand how you can tell the program to run with the graphics card instead of the processor.

[Dark0Lord7]

@GroogFish The physics engine does it.

[q1993p]

it looks like more like jell than liquid and sucks..

1 reason to don't buy nvidia for my next computer

[trecool9992]

@q1993p You're serious? LOL

Like you're going to get anything as remotely as cool with something from Microsoft hahaha

[q1993p]

@trecool9992 say the true this shit doesnt even look like liquid........

its awfull!!!!!!!!!! omfg I cant believe its not deleted yet for dis advertising nvdia.

[trecool9992]

@q1993p Please remember that this was release two years ago. We have a much more realistic NVidia water/smoke demo now.

[AndrewFaulds]

@q1993p Idiot. This is not about what the water looks like.

It is about how it moves like real water. Physics, not graphics.

[q1993p]

@AndrewFaulds even though there are different kinds of liquid... and you cant

claim that same physics apply to all liquids, one example is liquid helium.

However the particles of the liquid move awful and repeatedly. Something that wont

happen in real life.

[AndrewFaulds]

@q1993p Please... look up fluid dynamics. From 0:48 onwards it is very realistic, however it isn't running at full speed.

[q1993p]

@AndrewFaulds on 0:48 left corner down on the building u can notice after watching that the liquid is repeating. Also there are other parts if u pay attention.

[AndrewFaulds]

@q1993p It isn't repeating. It just has an unnaturally consistent stream of water.

[90marlboroman09]

cool

[superpoopermonkey]

thats fuckin beast

[90marlboroman09]

i would say ATI is much better

[zihaogood]

lol better in what? the only feature i find amazing is eyefinity, while nvidia has feature over power.

[Majorhavoc20]

actually, the framerate is ok, not better in the hardware version, it needs to be faster to be realistic. But hell, its a real good example of whats to come.

[Majorhavoc20]

This is a really good, much better than havoc, which just shows stuff breaking.

When it switched off the shaders for the physics it just showed many balls. Just wait as more advanced hardware comes out, more objects and collisions will be present and the smaller the balls can be so fluid dynamics will be awesome

[MumsOnAPlane]

I have to say that does look pretty good, gonna download the software, lol thats not lame!
