Water Fluid Physics Nvidia Demo 2

[khijasmith]

some great inforamtion here thanks

[smuggecko]

i enjoyed this vid

[AgainSpawn44]

Imagine this water being in future games :3

[takatoekoe]

fuck nice

[pipoxXD]

increible :D

[698152001]

if my computer has its gonna explode

[Olpster]

AND NOW IMAGINE THAT IN GARRYSMOD

[Baxten123]

@Olpster YUSH!

[jneidlow]

@Olpster That'd be awesome but imagine the lag.

This stuff looks awesome

[Olpster]

@jneidlow

not if you have a gamer-gamer-gamer-gamer-gamer pc^^

[jneidlow]

@Olpster True.

That'd be powerful as can be though like a quad proccesors and they all would have to go at like 4gh and have one heck of a graphics card

Point is it would be laggy until they make a serious computer.

[BIOSHOCKFOXX]

That's more like Jelly thing not like water, water is more...dunno how to say in english, but not like JELLY ...this video shows more like jelly thing.

[3kliksphilip]

@BIOSHOCKFOXX You want more particles and less sheen by the sound of it. Which will happen as they add more and more detail to the simulation.

[clownbabydiode1]

@3kliksphilip

More Detail!!!!

this already would lag too much!

this would clearly single out tens of thousands of pc gamers, you need a high high end pc for this

my point being is this is not a good idea to be going about this for now, not yet! (pc's need to advance more my friend)

they need a different approach that is much better optimized

I have thought of something (wasn't hard)

not enough space to explain on this post

[clownbabydiode1]

It consists of

1. A dynamic sub surfaced mesh surface capable of being manipulated by impacts ( displacement map of sorts)

2. A dynamic refraction and reflection shader and texture with a Fresnel effect (also capable of being manipulated by impacts but dependent on how the mesh surface is moved)

3. Physics Calculations (Depth, Mass, Acceleration, Velocity, Impact few more needed

4. Splash, bubble, steam, foam etc. particle effects dependent on impact

[3kliksphilip]

@clownbabydiode1 Sounds like you know what you're talking about. Remember that the simulation shown in this video is being run on a geforce 8800- the next gen of consoles / current day hardware will be much more capable of running things like this. No doubt we'll see very impressive examples in a few years or so, especially when this sort of thing is optimised to some extent. Just wondering, would your method simply lead to a 3D surface that could ripple? It wouldn't be totally dynamic.

[clownbabydiode1]

@3kliksphilip

yes it wouldn't be as flexible as 2000 small particles

also there is more to it

I will make a complete description in a MS word document, and upload it, couldn't hurt to check it out

i will post it here when i am done

[3kliksphilip]

@clownbabydiode1 You'd like the game 'hydrophobia'. I think it uses the same sort of system as the one you're suggesting. To me, the 'real thing' (Like what's shown in this video) is more interesting, since it can work in any game environment and doesn't need loads of trickery to look good. It's the brute-force approach, but it's the only real way I feel that you can properly model water. Look up the Nvidia 2010 GDC lighthouse video, it's impressive.

[dragonryder99]

Anyone know where i can download this?

I cant find it on the site the link directed me too

[3kliksphilip]

@dragonryder99 It's at the very bottom.

[dragonryder99]

@3kliksphilip Oh, thanks but if i try to start it up it says it wont work for me it comes up as 3 errors

[3kliksphilip]

@dragonryder99 What's your graphics card?

[dragonryder99]

@3kliksphilip Its a default acer latop card.Which idk what it is but its pretty low.

[3kliksphilip]

@dragonryder99 Probably doesn't support physx. You'll be unable to run this on anything other than nvidia graphics cards with at least dx 10.

[TheBlackBritt]

@3kliksphilip will it run on the Gtx 480?

[3kliksphilip]

@TheBlackBritt Yes

[powxpurplexx]

@3kliksphilip

Can you make fluid like that on a map

[3kliksphilip]

@powxpurplexx Not yet

[powxpurplexx]

@3kliksphilip

closest thing to it would be dynamic water

[3kliksphilip]

@powxpurplexx What's 'dynamic water'? Isn't a real-time fluid simulation an example of 'dynamic water'?

[powxpurplexx]

@3kliksphilip

/watch?v=TBLXLIqLmWE

[3kliksphilip]

@powxpurplexx Pretty much just physics objects with a water texture. Might be fun to play around with for a while, but I reckon it's severely limited in its uses.

[powxpurplexx]

@3kliksphilip

The problem with dynamic water is it can slow down and lag your map/computer fast. Even if you have nvidia

[3kliksphilip]

@powxpurplexx 'nvidia' isn't a graphics card, it's a company. I'm aware that dynamic water is expensive to render, which is why we haven't seen many examples of it yet. As computers get faster we'll see it becoming more and more common, especially if nvidia, amd and intel can reach an agreement over which technology to use to render the water. (Nvidia's PhysX can't be used by AMD and intel, so the chances are no games will adopt it properly)

[iamismeallright]

@3kliksphilip

you're stupid, amd CAN use physx.

[3kliksphilip]

@iamismeallright How come they don't then?

[iamismeallright]

@3kliksphilip

nvidia licensed it and made it, but amd/radeon cards CAN use it.

[3kliksphilip]

@iamismeallright ...in other words, they can't because nvidia won't let them.

[mrpeanutbutter98]

0:46 Oil Spill. Yaaaay!

[ratchet606]

looks like jello :)

[TheTrane59]

0:25 so much blood

[MaxOblivion5]

They should make a game called "Flood" Using mainly these physics.

[3kliksphilip]

@MaxOblivion5 Hydrophobia is the closest to it yet.

[UnstableUranium]

@MaxOblivion5 u may have given away a million dollar idea

[3kliksphilip]

@UnstableUranium COUGH hydrophobia

[WelcomeToTheGunShow2]

@MaxOblivion5 Are you trying to destory my computer?

[Blaze6108]

what about if I have an ATI Graphics card?



[3kliksphilip]

@Blaze6108 Sadly they don't have any comparable demos.

[derbigpr500]

@Blaze6108 Then I feel sorry for you. :P

[dograbbitbeaver]

@Blaze6108 ATI have more raw processing power, while Nvidia have cuda and physx etc

[3kliksphilip]

@dograbbitbeaver A bit of a generalisation. In fact, nvidia has always been regarded as the brute-force approach, while ATI tends to opt for clever techniques for optimising power. But of course it depends on which graphics cards you're comparing.

[dinosaurus1337]

good job now give us all super computer"s and make it playable.

[3kliksphilip]

@dinosaurus1337 I'm flattered you think that my 4 year old, £700 computer is a 'super computer'.

[3kliksphilip]

@dinosaurus1337 Oh God, having seen the frame rate in your video I pity you.

[luky01ful]

nesesito una mejora de graficos como esa

tengo una nvidia geforce 4000 MX de 128 MB

y juego juegos como Counter strike source pero cosas como agua se ve como si el agua fuese color crema osea, no tiene refleccion la graficas del agua se ve seca, sin ningun brillo ni reflejos

[justtoletyahknow1]

the stuff its tar... :O!!!

[123Invalidas]

This thing will be at some new games like half - life 3

[Rubenwbrk]

do i need a Super computer?

[3kliksphilip]

@Rubenwbrk No, you need something that's at least as powerful as a low-mid range graphics card by today's standards.

[AverageGamerz]

The physics are great but the particles look like jelly

[CptCool2]

@AverageGamerz Yeah, but there's only so much you can do, at least we're able to render it in real-time now.

[softilol]

@AverageGamerz thought the same -_-

[3kliksphilip]

@softilol It's a bit like when the first 3D games came out. They were low detailed and messy looking. As time goes on and computers become more powerful, they got better and better. The particles in this water simulation will also get smaller and smaller.

[GiveMeBass93]

That's what happens when Chuck Norris takes a piss XD

[turb233]

Now if only Counter Strike: Source had this good of water.

[teletubbiepwnzer]

@turb233 it never will

[Robloxblacky]

:21 saw movie bloods :26 nickelodean slimes ;35 where drinking it water!!!!!!!

[Sancor93]

where are the bubbles?

[mentosC4]

0:22  nigga look at all dat koolaid!

[rockgod111]

Thats puuurdeh

[mhaneline]

lol @ scared stiff of Intel's new graphics card.

[3kliksphilip]

@mhaneline What's that?

[mhaneline]

@3kliksphilip A quote from the About section of this video. Quite humorous to be sure.

[3kliksphilip]

@mhaneline Ahh, removed from the description now, thanks. I'm impressed by how much of a flop Intel's Larrabee was.

[The3Joker]

This should be in Garry's Mod!

[3kliksphilip]

@ComicAzie Read the description, it's realtime.

[Soulslayerzx]

We actually could do this, if someone made really good textures and made some good flowing patterns

[Soulslayerzx]

So how did you make this? With hammer? So i can use this in a mod?

[3kliksphilip]

@Soulslayerzx Read the description

[3kliksphilip]

@Aioner1997 Remember that this is a large model, if you watch a dam exploding you'll see the same sort of slow-motion effect. What this simulation shows is that real time fluids are possible to render in real-time. This was on a geforce 8800, the equivalent of a Geforce 530 or something today. The new high-end cards are probably 4 times faster at doing this sort of stuff and could no doubt do a much better job at it. next gen consoles should make it mainstream.

[roshawn1111]

@3kliksphilip well to be truthful its kinda a waste as aioner1997 it doesnt move like water nut hey its a very good start, further more i dont think its ever gonna be mainstream, as water has its own physics with dx 11

[3kliksphilip]

@roshawn1111 Really? I didn't read anything about that in the dx 11 overviews I've been reading.

[roshawn1111]

@3kliksphilip reading and playing is 2 different things take lost planet 2 if you disable dx 11 water does not move when he runs through it, if you enable it its moves to the motion of him running and i dont have a nvidia card i have ati.

[3kliksphilip]

@roshawn1111 Are you sure it isn't just dx 11 tessellation making the water 3D? I'm pretty sure the physics aren't anything to do with dx11.

[roshawn1111]

@3kliksphilip maybe its that but i say either way its not really needed and dont very many games use it, and the 1s that do dont use it that much

[3kliksphilip]

@Aioner1997 Could you explain how proper water is different?

[MEKON17]

i don;t know what i am watching. hoho

[Kcon83]

@3kliksphilip

I think it was a matrox g200 or 400 can't quite remember. I do remember having an S3 savage with "s3tc" texture compression ! :)

[Kcon83]

@Mrboblebob

I used to have a matrox card "eons" ago, and that was my first glimpse of bump mapping. I'm not really a guru in that sort of stuff to be honest but understand some of the basic principles though.

[3kliksphilip]

@Kcon83 Matrox Millenium with 3 monitor support?!?!

[UnladeHint]

What DX version is this?

[MrBoblebob]

half of the ppl whatching this dont know what they are whatching.

the other half dont belive it.

[3kliksphilip]

@MrBoblebob I agree!

[MrBoblebob]

@3kliksphilip 4 me this is absolutly enough for a game. cant imagine how cool it would be at gavity zero.

looking forward to source engine 2.

[RandomPieGuy]

1:00

"Alright, who the FUCK replaced our water with packing peanuts?"

[manstie]

0:21 O NOES ITS BLOOD D=<

[o0ZporK0o]

i just realised that my first comment probably delayed hl3 even more.

[Kcon83]

Some of those balls disappeared, why???

[MrBoblebob]

@Kcon83 if you mean the small white ones, those where particles as water. the dissapear because new ones abear an to much of thos would be hard for the computer to render. how i see it i think the "balls" make a bumpmap as the form to gether in a pool. that makes the computer to render even more water.

i don't know how much of this u understand, but gamers today isn't what they used to be. :(

[joealtair3000]

looks like gel or some form of jelly

[MrVladdavid]

man 0:48 it looks like prototype

[imabee232]

0:46 BP strikes again 

[o0ZporK0o]

Why do I feel like this would be good for a portal game? Anyways, is source capable of anything like this?

[3kliksphilip]

@o0ZporK0o Valve could implement a technology like this, but I doubt they will.

[o0ZporK0o]

@3kliksphilip yeah, valve does like to keep their stuff pretty basic, dont they

[3kliksphilip]

@o0ZporK0o Yeah, they let people run their games with minimal hardware power, but with both HL1 and HL2 they included enough options to be able to tax high-end computers, I'm hoping they continue this tradition!

[HaloReachingers]

@3kliksphilip Isn't the propulsion gel in Portal 2 sort of like this though?

[3kliksphilip]

@HaloReachingers Kind of, but I doubt it retains its mass and weight, and probably doesn't really interact with the surroundings without becoming a simple painted on texture.

[HaloReachingers]

@3kliksphilip yeah, you're right. Its obvious that the propulsion gel doesn't interact with its surroundings at all.

[Soulslayerzx]

@3kliksphilip: don't they like geforce now? Half life 2 deathmatch/portal are free to download if you have nividia geforce graphics cards.

[rocker9904]

@o0ZporK0o maybe.... i think it needs 5 years. i want WATER, not JELLO. :)

[o0ZporK0o]

@rocker9904 lol

[o0ZporK0o]

@rocker9904 it only looks like jello because its completely colored, un-like water. if u made it clear it would look better

[bazook1935]

hmmmm that made me thirsty for some kool-aid :D

[sharpezor]

the goggles, they do NOTHING

[kylethehedgehog101]

@sharpezor lol, is it a good idea to microwave this reference FTW

[C0Opd0g]

Not much in the way of splashing affects...

[mycallmichael]

i wish you hold and angle a little longer...

[3kliksphilip]

@mycallmichael If you pause it it'll remain at the same angle for as long as you want :)

[mycallmichael]

@3kliksphilip but the water wont be flowing.(in motion). you must have hit the same angle at least three different time. Instead, hold it at one angle for an alotted time, then shift. instead of constantly toggling between angles. Love your videos though. thanksXD

[trlababalan3000]

@3kliksphilip I think he wanted to see it moving at specified angle...

[cracktober]

I need to know what you think of the radeon 4650, i got one in 1gb, with a 2,8 hypermemory, DDR3 vram

[3kliksphilip]

@cracktober The most important thing is the model, 4650 is a mid-range card, it's unlikely to run recent games at high detail settings. 1 gb doesn't really matter for a card of this power. I've got an ATI 4850 with 512 mb of ram, but it's a lot faster than yours will be.

When you ask what I think of it, what do you mean? Which games?

[cracktober]

@3kliksphilip well the thing is im surprised that this is on a laptop, ive had it for soon a year, and it runs GTA on high, and fallout 3 on highest, every new game (call of duty, bad company etc) on highest. More demanding games lkike GTA cant be run on highest, I havent tried crysis yet but according to the recommended specs it's more than enough.

[Intensefunkid]

SOOOO MMUUUCHH BLOOOOODD

[DantoraMandova]

God, liquid is soo hard to fucking render. When I'm at the beach I feel as if sometimes life lags...

[RickTheStickman2]

Hey what's up bro?

I heard you like NVidia so you could put a GTX 295 with a GTX 295 so you have a fucking huge gaming rig with SLI activated.

[3kliksphilip]

@RickTheStickman2 I thought the 8800 was an excellent card, which is why I got one. Since then they've been lacking, but the 460 and 580 aren't that bad. ATI still has the edge though.

And no, a 295 with a 295 would have minimal performance boost, since they're already SLI on their own, and there are better performing single cards with lower TDPs out there. You need to keep with the times, bro.

[RickTheStickman2]

@3kliksphilip

cool

[warpigswithnofaith]

@dasantinazibroechan: then speed up the video, its not gonna be realtime for a long time coming :3

[3kliksphilip]

@warpigswithnofaith ...this is in real time.

[warpigswithnofaith]

@3kliksphilip oh... specs?

[3kliksphilip]

@warpigswithnofaith The gpu is the geforce 8800 gts 640 mb

[G3org3Master]

Is this made during runtime or is it pre-made? and if you move boxes infront of it yourself will the water hit them?

[3kliksphilip]

@G3org3Master It's all done in real-time, I didn't make it, and yes, the boxes will interact with the water.

[myrandomnoob]

0:47 OIL SPILL!

[vef444]

OMFG!

[gamefreak5671]

crome water........then balls wats next?

[WoLF2Own]

Soo.. How they made this xD?

[JayTmatrix]

Hey !! :D.. Virtual pool-party !! :D

[thehumor]

where can you download this? i wanna do it too :D

[manrayer88]

Maybe one day we'll be able to simulate GAS

Oh god

[3kliksphilip]

@manrayer88 There's actually another nvidia graphics demo that shows that :P

[DasAntiNaziBroetchen]

@manrayer88

uhh... gas simulation is pretty old already...

[TheFlow666]

@manrayer88 gas is pretty much just water with gravity reversed simulation-wise anyway.

[worldofwarcraft600]

it would be cool if you coud be a person and run away from the water

[Tossavainen1]

@worldofwarcraft600 Some day in the future, my friend..

[ShredderOMG90]

Kool-aid?

[jbcdu87]

its good physics, but theres something missing that you see in water, when ever i see this demo, it reminds me more of some mashed up jelly than a liquid. its still good though! i can imagine hl2ep3/hl3 to have a map with this, surfing with your airboat on a wave :)

[DasAntiNaziBroetchen]

@jbcdu87

that would be cool^^

btw, if the water would move much faster, it would look way more realistic.

and if the particles were smaller, it would look almost lifelike.

[osakanone]

It lacks a kind of frothiness that aggressive water has, defined by the number of actions or 'violence' of the water that we see as surf in waves.

[3kliksphilip]

@osakanone I don't think that anybody thinks that this example is perfect, but they've got the most difficult bit of water physics right. To see anything like this in real-time is a testament to how far we've progressed and once more systems are able to handle things like this, we'll see people pushing them further and making more realistic AGGRESSIVE water simulations! :D

[tragedy1101]

how would this go with sperm?

[eninco242]

0:22 SO MUCH BLOOD!

[rotjesenmatjes]

0:48 Welcome home BP.

[TheTerraTitan]

@rotjesenmatjes

Damn. You beat me to the BP idea. Nice thinking though.

[DGMRuadeil]

The huge fps update is simple to explain. Before, with the 0.3 fps, it used software physics calculation on your CPU, with later drivers it used hardware physics calculations (on your GPU). This is much faster because your gpu is simply much better at floating point calculations and can do it parallel. Its like software vs opengl/directx rendering in the old days.

[3kliksphilip]

@DGMRuadeil What I meant was that before Nvidia acquired Physx, it would run at 0.3 fps, while afterwards it would run at 30. Since Physx was advertised to show how amazing their Physics card was, I found it a little absurd that Nvidia bought them and was able to enable support on graphics cards that had been released from before that time- proof that Physx is nothing more than just software.

[DGMRuadeil]

@3kliksphilip Did you have a physics card when you ran it?

[3kliksphilip]

@DGMRuadeil No, a geforce 8800.

[DGMRuadeil]

@3kliksphilip Before nvidia bought it, physX simply ran in software mode because it couldnt find any physX hardware card. When nvidia bought physX, they rewrote the hardware interface to use their videocard. This has nothing to do with nvidia being better or not.. its just that before, the software driver didn't know how to use the nvidia hardware, but only the physX hardware. This would've ran a lot better then 0.3fps if you had a physX card too back then obviously :P

[3kliksphilip]

@DGMRuadeil Yes, I understand that. I just wish that Nvidia would let AMD and other companies to also use PhysX, because then we might actually start seeing decent implementations of it in-game. At the moment it's simply splitting the market thanks to Nvidia's selfishness. AMD's open-source physics solutions are much better for PC gaming as a whole.

[DGMRuadeil]

@3kliksphilip maybe, but that is just commercialism. I've never been a fan of ATI/AMD. Their linux support is horrible, and their drivers aren't so great either as a whole.. even on windows. Things like this will change with the comming of openCL within a few years. Then any library can "easily" implement things that use a GPU, on any brand that supports proper openCL.. which will probably all major brands including nvidia, ati and intel

[unkowndrunkenfrankli]

@3kliksphilip my 8800gt supports physX, so should yours

[3kliksphilip]

@unkowndrunkenfrankli ...hence why I recorded this video with my 8800. But I didn't have a physics card at that time.
