Particle Fluid With an Ageia PhysX Card

[macskap]

Name of the song??? I mean the original one.

[Snorkorsys]

@macskap the song is 99 Luftballoons - originally by Nena

[Shas221]

look at the size of the particles, way to large we are not supposed to see that those are individual particles, then i will call it AMAZING

[aronjakob]

if they where going to do water like it is in real life they would roughly neeg a computer 1000 tomes more powerful

[kjulssfl]

this tests can be executed on PIII with FPS 50+

[iOWNu1111]

i downloaded 3d mark vantage and it had that with it, i dont even have physX, i have a 4870 and i can still do that!

[speedaddict2008]

It's not the GPU that processed the PhysX, it was your CPU.

[iloatheyoutoo]

I like this song in german...

[valveforlife]

your running it in software mode:I

[paimail21]

WHERE

can you get a PhysX card?

[TheOnlyDuST]

you dont need one... all 8 series and up nvidia gpus can do physx processing on them

[KEOBand]

They are doing it wrong. Lots of small particles? Sand might be made that way, but not water.

[Aeoxins]

Everything consists of small particles.

[KEOBand]

Okay... I just think they should try something else, that's nowhere close to be like water.

[speedaddict2008]

what the? dual core pentium 4 :|

[TheOnlyDuST]

damn dude im on 1.8ghz and a crappy nvidia 6200 tc 16mb with no ppu and i get 110fps?!?!?!

[damien345]

yea but more you put shoot physics your framerate get very low shoot 60 balls well talk about it later lol

[TheOnlyDuST]

mine dosent slow till i shoot a couple hundred but i only have 15 processes runnin and nothin else is usin the cpu

[xNighthawk177x]

lol

[Exhonour1337]

its a sweet idea, not yet fully developed

[speedaddict2008]

LMFAO! I had WAY better fps on that demo,and I don't have any PPU.Or is it just Fraps that slows down your framerate... :)

[jayfeedog]

wtf i can do that without the PPU...

[operationturkey]

Yes is can all work on the CPU. However the ageia PPU can run physics calculations much faster than a CPU, so with lots of physics effects it will help maintain good framerates. Try playing warmonger. It's a free game running the physx engine, and I can tell you it's not going to run fast without a PPU or GPU acceleration using CUDA.

[YAGUTAN]

It simply takes the load off your cpu in PhysX enabled games.

[DragonTamer2345]

Where can i get this program? Or does it only come with PhisX cards? I'm Ccurius to see how bad this crushes my Pentium D...

[dibbuck]

Hmm strangely unimpressive as a demo of processing power as not really that many particles doing nothing really out of the ordinary. But good fun though.

[girlsdrinkfeck]

also the fact that crysis runs PERFECTLY with my quad core and handles all physics really well without slowdown , so them cards r not needed unles u plan to use very power tasks

[Nightcover]

Well, although Crysis physics looks impressive. It is just huge junks of the buildings falling off, and you can't destroy them to smaller parts. Crysis has amazing physics, but it's optimized for CPU's and because of that, the physics isn't as advanced as it could be. Crysis also have no physics in the water. Because that requires a lot of power, something only the GPU or PPU can handle. I understand why people "think" Quads can do all the work. But sadly thats just not how it is. (count limit)

[girlsdrinkfeck]

but no games yet use so many particles for physical realism , and when they do , we'd already have mass multi celled cpu's to do the work, id asume so anyway

[Nightcover]

The reason they don't is that there haven't been the power. But with CUDA, there is now a market for it.

[DragonTamer2345]

The reason that games havn't had alot of small particles is because there hasn't been enough power for them. If Ageia can get this thing off the ground then games would change... alot.

[RebelForce8]

Its not "fluid" its a lot of small blue squares..that was lame

[ShortStuf7]

Its particle-based fluid physics, not caustics. Physics not graphics. It's the physics that were the main focus, and not the appearance, therefore no metaball shader effects were added.

[NightwishRune]

those small blue squares simulate fluid genius

[AquaGeneral]

The reason why you only see squares is becuase there is not any mesh being generated. Regardless you would not have to see real looking water to see that it is physically accurate.

[niiidar]

holy fuck you must be einstein.

[girlsdrinkfeck]

ah well , physics cards are no longer , multicore cpu's handle most of that now, good idea at the time tho , im so glald i have a quad core

[ShortStuf7]

Yeah same here; I have a qx6800 now. Quad cores rock.

[realflow100]

@ShortStuf7 omg i can play this without a physx card in realtime 104FPS constantly (the first scene on your video here) ftw i have (quad core intel virtual CPU 4.10GHz) plus (2GHZ AMD Athlon dual core) so i have 6.10GHz basicly

[realflow100]

@ShortStuf7 and i almost forgot to add i have ATI Radeon 3100 lol!!! still over 100FPS for all of the demos...amazing!

[realflow100]

@ShortStuf7 in full screen...

[Nightcover]

Well no, Quad-cores even though it sounds impressive will never be able to render the physics as good as a GPU or PPU because of the algorithm. Physics requires a lot of calculations at the same time, thats why a GPU or PPU is good at it, because it got many streamprocssesors. Indeed a quad-core is powerfull, but it is not made for those task, it is made for big task witch requires a lot of computing power on one calculation.

CPU = Few big task

GPU/PPU = Many small task.

[girlsdrinkfeck]

well , that might change, intel r wanting to go into the gpu hardware market and make cards powered by 80 odd cores under the x86/64 design and make the conversion tools for the programmers if they wish to not build games using this technology wichll make it easier yet more powerful and better optimised

[Reapper93]

ati sucks like your face

BUY A NVIDIA GeForce 8800 Ultra KO if u whant good performance u fag

i hope you burn n hell along with your ati

[ShortStuf7]

Agreed, that was my old computer with the ati card. I've upgraded now man, take a chill pill.

[RebelForce8]

a chill pill eh ? gonna get me some those (runs to store)

[darkshiv]

OMG! Whats this song???

[socomegaton]

99 red baloons

It's sooo old.

This is a modern version.

[bangity]

why ppl complain about a cheap physx card hat only cost like $99, just spent it

It does improve the Physic and framerate even with games that don't support it. tested with my 8800GT

very little improvement on the framerate side, at least it didn't decrease in framerate but the thing is you get some good physics and things fly around, it's much better (with games that supported it)

It does show improvement over the 8800GT, bit not much though

haven't tested physx enabled game, just regular ones

[asweran]

Why would ou but a ageia physics card for an 8800gt? The geforce 8 series come with built in physics units.

[qwertymac93]

the whole video was actualy showing off your cpu, not your physics card(thats why it said software) put it into hardware mode first dumbass. although the gravity ball is fun to play with, esdesialy when you make it spinn full blast and it explodes.

[Cylon7x]

NEWS:  AGEIA PhysX ACQUIRED BY NVIDIA

[qwertymac93]

you've got to be shitting me. damnit i hate nvidia, at least amd owns ati now.

[LiLBoy1221]

name of song anyone? =]

[pk3r72owns]

99 red balloons

get goldeneyes version much better

[Voldin2901]

i can run this without that stupid ageia physx card.

you need it only for one game and thats warmonger.

[davidstop]

What kind of fluid solving is being done here? It just looks like normal particles

[msndokaralho]

How can I get the ageia PhysX card?

[Cylon7x]

in a Computer Hardware Store buddy where else?

[msndokaralho]

This would be hard, couse I live in brazil, here there's a huge lack of everything related to computers :(... Maybe I could found it somewhere else =3

[Cylon7x]

ow

buy it online theres many good sites

try newegg, etc good luck! ;)

[WholeWideWorld]

Done with nvidia GPU.

Good fight PhysX

[bassamnz]

does this program come standard with a PC woth a PhysX ?

[DataCain]

qwertymac93 - you're a nub.

[peterfaj]

this "fluid" looks more like some sand

[stefdom3]

I did this earlier without a PhysX card. Don't look much different to be honest.

[yougotzd]

That is awesome....

[qwertymac93]

im a firm believer in physics on the cpu, its just easyer to get a 400 mhz cpu then a 400mhz ppu.

[AnnoyedDragon]

As long as you fully understand the pros and cons of CPU physics; I have nothing against those who prefer it, there are merits to keeping it on the CPU.

But I often find those who do prefer the CPU over PhysX and Havok FX tend to have a... over optimistic view of its capabilities, what it can bring to gaming and the time frame in which this is possible.

[qwertymac93]

what i ment was that its easier to upgrade say, a 2.0 ghz cpu to a 2.4 ghz cpu, but since their isnt hardware acceleratio, the physx has more realistic simulation.

[AnnoyedDragon]

A 400mhz boost won't do much for physics, it's not the same as a 400mhz PPU.

The benefits of the PPU and GPU is they are both parallel processors; the CPU on the other hand is mostly linear, physics being a highly parallel task means it will run significantly better on parallel hardware than the CPU which will require many 'many' cores.

Also considering the nature of CPU utilisation in games, CPU physics is the very 'very' slow but steady method of improvement with a superior install base.

[qwertymac93]

look, ppu is good but it needs to be more widly used, im not going to spen over $100 to use it in half of my games, and nothing else, if it was used more like a gpu(it works EVERYWARE) then i would DEFINATLY get one. a ppu is better then a cpu but its just not enouph, in a few years it will be a better choice.

[AnnoyedDragon]

Whoa there, you make it sound like I was trying to convince you to buy one.

I was just explaining how 400mhz on the CPU is not the same as 400mhz on the PPU, since you refer to just adding it to the CPU to make up for the lack of a PPU in two of your posts.

[qwertymac93]

you missunderstand, i ment its cheaper but less performance, but like i said, im going to wait untill the technoligy is more mature and developed, and of course, more compatible.

[Duodecimal]

The problem is, since the instant gratification crowd isn't seeing what they saw when GPUs first hit the scene development is going to take it's own sweet time. Small demand = slow development. It's near infuriating to hear people(Not pointing fingers here) whine because they can't envision what the PPU can do for us. I'd rather have my CPU doing coordinating and AI, my GPU rendering, and my PPU(I wish I had one) processing physics.

[qwertymac93]

IM NOT PAYING FOR SOMETHING IM ONLY GOING TO USE FOR 50% OF THE TIME< I'LL WAIT TILL ITS 80%!!!!!!! was that clear enouph?

[Duodecimal]

Wow, spaz out on Youtube why don't you. Hey, remember when I typed "Not pointing fingers"?, cause man I do. It was awesome.

Oh, and retard, no one is telling you to buy anything except maybe some Valium.

[qwertymac93]

what? hay, im not the one calling names like a 5 year old.

[matttd9490]

Im with you. Whist yeah the physix can be impressive. Id rather stick to CPU. cause the Phyix cards are pretty much useless, unless you have the correct selection of games. So unless you obsesest with physics and rather watch a tree blow in the wind more "realisticly" and inpress your geeky friends. Id rather stick to my CPU untill these Physix card are an actual benift not useless curcit boards.

[qwertymac93]

thanks you, god, someone with a BRaiN.

[Hrakleus]

Totally agree but just to let you know:

When you crossfire 2 card you can choose one card to be rendering and one to be Physx.

So instead of crossfire ageia seems fine.

Still not so useful though...

[AnnoyedDragon]

Actually you cannot; there is not a single released game or driver that supports physics on the GPU, let alone crossfire/SLI.

Of course, thanks to recent events with the Nvidia purchase, that will change in the future.

[qwertymac93]

yes actualy, you can, but most people use it with a 3 card configuration. and a ppu is basicly a gpu :P just more optimized.

[AnnoyedDragon]

Let me repeat: "there is not a single released game or driver that supports physics on the GPU".

If you think otherwise; you have been told wrong, there are no games out that use the GPU for physics processing. There have been tech demos and articles discussing the concept, but no retail games.

As for the PPU being just a optimised GPU... go read up on the difference.

[qwertymac93]

they are diferent, but im sure there all still based on shaders.

[AnnoyedDragon]

GPUs use shader piplines while the PPU used physics tweaked vector processing units.

If they were so alike; GPUs wouldn't have so many architectural problems that the PPU doesn't, Nvidia wouldn't have to rewrite most of the PhysX engine to get it to work on the GPU.

[qwertymac93]

vector... gpus have those, or are they vertex... hmm, im pretty sure they are specialized vertex/vector piplines.(just like gpus use hardware vertex shaders, instead of the cpu doing it in software emulation. its the same in a ppu, they are special proccesors made for physics while gpus use their unified shaders to emulate the vectors, yes it can do it, no its not as good or as cheap.

[AnnoyedDragon]

Whatever the case, it still isn't as easy to do physics on the GPU as it was with the purpose built PPU.

If even half of what I have been hearing Nvidia has planned is true, their new solution is going to be worse off than the PPU.

[AnnoyedDragon]

I see as usual some people have no idea what they are looking at; they expect eye candy then become disappointed when they don't see it, they don't realize this is about affects not effects.

[qwertymac93]

not much memory in that litle card is their :P only like 100 dots man, liquid is more like 1000 for one gallon, not 100.

[AnnoyedDragon]

It is just a tech demo showing a proof of concept, if tech demos were used to estimate PPU performance then people would have ignored it after the first cube demo.

Real world implementations such as Cellfactor, BOS, UT3 and Warmonger are best used to judge capabilities.

[acleansweep]

lol, make that more like 10^25...

[qwertymac93]

1000000000000000?

[acleansweep]

10000000000000000000000000

[qwertymac93]

lol.

[beatsiz]

im 5555th viewer!!!!!!!!!!!!!!!!

[TNTorsten]

You have an Ageia physics card? Why then you running in software mode?

Btw. it doesn't look likes fluid, you can just use it for physically particle.

[thechevron]

this is a bad video, it doesn't even look like fluid, it looks like hunners of wee bawz. there is a better fluid on on the website

[psychodantis]

It's okay, but Nvidia's GPU water physics demo is better (In my opinion.).

[AnnoyedDragon]

This is a simple fluid demo that easily runs in software, Nvidia's demo uses hydromechanics accelerated by the GPU. Ageia has plans to implement the same technology into PhysX but it will take a good couple of years before any games utilise it.

[DudeParallel]

Here i have a little project for you, create a slinky

[RafaLL92]

why is the first fountain running in software mode? shouldn't it run in hardware mode? I can see you have PhysX card installed...

[ShortStuf7]

It should have :P I must have forgotten to switch it when I took the fraps vids.

Oh well.

[Calasphere]

...

[RexNunc]

way cool

[AnnoyedDragon]

It is a good video but it would have been better if the particles were blended together like most fluid simulations. As it is it looks more like large sand particles rather than fluid.

[Argoon1981]

Cool the fountain was realistic, i have one were i live and it works just like that. I hope to see more liquid usage in games as gameplay physics and not so effect physics.

[AquaGeneral]

Thanks mate!

[AquaGeneral]

Is there any demo to download of this?

[ShortStuf7]

Yeah, it's the Ageia PhysX SDK demos.
