Cool! I though so many times that computer games are close to reality... But i always become so wrong when new technologies appear... Now I see: there are so many ways to make complettly new games with new mechanics! People can do fantastic things with such technologies!
I would like to see a city that will wash off with tsunami :)
And every new destruction will be quite different due to this technologie!
Why does people complain how it looks if you compare with what we used to have. Sure I do agree with the viscosity but this are great news and looks GREAT! Think of the feeling when this technology gets optimized and better and also when starts using within games! :) - I am waiting! :D
Why are so many people saying it looks fake? That was amazing! The way the water whipped up when the boxes were lifted, and how each wave collides with each other. I can only dream of the day this comes to games.
Eulerian Fluid flow is not a perfect representation of realistic fluid flow, and actually contains no viscosity parameter at all. The fact that the simulations look fake is probably due to the resolution of the grid and that there is no turbulence in this type of flow and hence less surface detail.
The lighthouse looks considerably better than all the other simulations. The lighthouse one is actually pretty good and quite realistic, especially compared to todays standards but the other simulations all looked very fake.
@Thet3 OpenCL, isn't that the standard no-one in particular is driving? Yeah, good luck with that. No offense, but Physx works and is already readily available to implement. It also has the advantage of the sole proprietor willing and able to send out engineers and programmers to assist in it's implementation; for free.
Nuts to OpenCL. Buy an NVidia card if you want neat looking Physx like this soon. Or wait a long time if you want OpenCL Physics.
devs know how to get water right, the problem is the performance hit that it implies so they try to fake it with more or less success, next-gen will have a much better virtual rendition of water and other fluids.
@px0128 noo :o then it will be too fast, and u wont have the awesome wave effect for long, you need to see this as if it was a big ocean, not a little lake, if you know what i mean, because water acts like this too when it large large amounts
@px0128 Not that simple. Any viscosity you see here is from numerical dissipation; there are ways to combat this, but the added computational cost might not be worth it. The dissipation isn't that bad, actually—it seems to me that a surprising amount of small-scale turbulence is captured, and doesn't smooth out super quickly. The method has: interactive speed, greater realism, and 2-way solid-fluid coupling. If you saw this in a video game, would you balk at it? I doubt there are many would....
Oddly speaking, if they are tracking the water particles, how do they call this Eulerian? it is still the Lagrangian or at least semi-Lagrangian frame for the equation that governs the fluid, which is the tradition way of fast simulation of fluid, gas, etc. Eulerian simulation would concern solving Navier-Stokes equation. I doubt any current GPU could reach 30fps in simulating Eulerian water, in that you only could use 1/30s to solve the eq on a 128*128*128 grids to some certain precision.
@Jonsoncao Eulerian Fluid flow refers to solving Eulers equations for inviscid fluid flow. Which are a simplified version of Navier-Stokes, eliminating viscosity. The paper that this video is referring to also assumes an incompressibility condition on the flow. I believe the whole point of this video is to show that this computation can be done efficiently for certain types of flows using the tall cell grid described in their paper.
its only 128 x 64? Now game scale is like.. Say river, 2000x5000?

Amazing. You could so easily increase the grid resolution and use this for large scale, high quality simulations.

yeah its a slow camera / slower speed in realtime, which makes it look like slime. it acts like water when running at actual speed.
