New fluid simulation algorithm makes water actually look real

[Jozi]

The new fluid simulation algorithm simulates liquids using Position Based Dynamics (PBD), which is the same framework that is used to generate the eye candy found in cloth and deformables simulation.

According to PhysXInfo, PBD’s iterative solver is better at maintaining incompressibility than traditional SPH (Smoothed-particle Hydrodynamics). Furthermore, PBD “has an artificial pressure term which improves particle distribution and creates nice surface tension-like effects.†It also allows user to inject energy back to the fluid via “vorticity confinement.â€

cool. crysis 2 and 3 looks nice but cmon water is holding the immersion back some what. games still look beautifal tho

I couldn't load much up but from 4 seconds of the first link looks bloody excellent, but also looks like you'll need a fair amount of graphical power to do that.

The next phase should add mass and force so a wave like they were showing would actually knock a character down or slow them down if they are moving in it.

And that's some nice water

nice going to need more gpus in my rig lol

Looks awesome. Great to see in up coming titles!

3-way SLI'ing GeForce GTX 690's, 6 1,536 core GPU's and something like over 15 TFLOPS of computing performance should do the job nicely:)

Can't SLI 3 690s :D

But yeah this would take a ton of computing power, I doubt that this will be used in games anytime soon.

wow that's pretty incredible!

 

they should have put some scenery around it, instead of just the plain models, to make it look more real.

That made me think of Wave Race 64. 

[ShiverMePenguins]

does it have the ability to be absorbed? like say in a jungle environment and water spilling into a footprint then slowly drenching the soil?

Crysis 10 and Far Cry's 10 graphics.

Proprietary physics engines don't interest me, they create market segregation.

I believe someone from NVidia said they may have a toned down version of PhysX on AMD cards, can't recall the source, I will edit it in if I can.

[Hans Christian | Teri]

They definitely have the physics down, but the graphics still needs a tad of work to seem realistic. :) It's such a hard thing to simulate right, not to mention the workload it puts on your computer. For full scale games I think it will still be several years before we see anything remotely like this.

We have had the ability to add foam and bubbles to realtime water for some times it just looks weird and realtime fluid in games dose not have a purpose right now only some games make sense to have it.

Well that sucks, just has to make do with two then:)

That looks OUTSTANDING !!
