GPU fluid simulation - water

[hitokiri657]

Naaah. Al thought simulation is pretty awesome for todays standards , the fluid needs more particle distribution among patches. Seems more suited for like the previous one a saw, viscous, blood.

@hitokiri657 Since its rendered in real time its amazing

[hitokiri657]

@1GTX1 Sorry for not being amazed.

[1GTX1]

@hitokiri657 Ok but find me better water simulation from 2007 that runs on GPU?

[TitanaMaster]

@hitokiri657 it's from the oldest water simulations on youtube, he deserves a thumbs up... Even I, when I was looking at it at first, said "oh my"... I was pretty amazed, but now it seems very common. well that's because of the rendering techniques used here which are old. there are some very new techniques which add noises to the water and it looks very realistic, but that's very new.

keep enjoining videos though. bye

[Tommygun1135]

The water seems a tad... Heavy and not really splashy enough...

[liamdudeeee]

@Tommygun1135 this is a pretty old demo, theres a really good one out there that nvidia showed off at some convention. i dont think you can download it though =/

[Tommygun1135]

@liamdudeeee I see... Interesting to see how fast technology evolves...

[regerttamas]

It is impressive! Is it a finite volume solver? What mesh did you use? Was it a simple Cartesian mesh with cube shaped cells? At what cell number can you compute real time? How did you handle the interface? Are you computing also the air above the water? Is it a mixture model, or a Volume of Fluid approach?

[Sevival]

your simulation only generates solid fluid?

[JuniorProducer1996]

its fantastic, but if this was ever implemented intyo a game, the GPU would be focusing completely on the fluid, and you wouldnt be able to render the rest of the enviroment to a fidelity much higher then an xbox 360 circa 2006...........but now that my pessamism is gone i do love the effect :D

[Staaatl]

Please tell, can i simulate on GPU or this a closed software ?

[wagawagawoo]

Remember before you criticize! This is REAL TIME!

[robinjam304]

Looks like clear treacle. Don't get me wrong - it's a cool effect. But it looks way too thick to be water :/

[riDDimann]

the cubemaps, lulz.

[YousefAB]

Too thick for plain water.

[jotham97]

For some reason this won't work on my rig:

Nvidia 9800GTX+

Quad core Processor

3gig ram

Any solutions?

[xpacterol]

mine has lag but still fun to play with =D

[MrFrederiktorp]

@jotham97 I have amuch better "RIG" just saying. But i can't either :(

[TheOnlyDuST]

am i like the only one whos computer hates the demo??? i tried the demo on a KFA 8600GT 512MB DDR2 and the water looked all mested up and the smoke wouldnt even appear... now on my MSI 9600GT OC 512MB it does the exact same..... i was using driver version 181.20 for both...

[DragonTamer2345]

is there anyway i can get this without a PPU? No, i don't have an Nvidia GPU

[fartnox]

ppu?

[DragonTamer2345]

Physics Processing Unit.

It's the heart of agiea physx cards. Though most Nvidia cards do the job well.

[TheOnlyDuST]

DragonTamer2345 this demo dosent run on a PPU also it requires an Nvidia card with stream processing units such as some kind of 8 series card or better i heard this will work on 8200 and up but exspect very low preformance on the 8200 since it has so little stream units and its an igp

[Capeau]

Do you know or can you say this stuff gets integrated in the nvidia physx engine?

That would be uber!

[MattOGormanSmith]

PhysX already uses GPU. I don't know if it uses actual CUDA or is written directly in shader asm. I'm pretty sure the teams at NV are closely linked.

[Capeau]

off course (its cuda) but last time i checked physx didnt do fluids. Hopefully they will put this in the next version...

[MattOGormanSmith]

I think PhysX is too low level to 'do fluids' as such. That's up to the app. PhysX can take care of the interactions between the particles, and gravity, but that's about it (although that's quite a lot of the problem).

If PhysX survives as an API, it will be because of marketing reasons, as new abilities in apps are credited to PhysX ver 9.0c instead of either the app, or whatever higher-level physics engine is being used and what gpu.

A good cross-platform API will win in the end

[unlicter]

Yep! I played it today, I have a 8800 GT, it runs like freaking butter but! the resolution is pretty low so I wonder how it would run in 1920x1080 LOL!

[ragdollpwner]

yeah real time, if you have a 8600-8800 :P
