[QUOTE=eddy-tt-;40412154]Watch as no one cares when it does get implemented into a game title as its physx only.[/QUOTE]
[b]PhysX is a physics library just like havok or bullet[/b], it's probably used in many games you don't even realize. For example, unreal engine 3 onwards is all PhysX according to wikipedia as well as many other engines such as unity 3d, gamebyro, and so on. It's also free for anyone to use commercially or not afaik.
Just because PhysX has an [b]optional[/b] feature that allows you to use hardware acceleration only on nvidia cards does not make it any worse of a physics library than any other. I much prefer it over the other ones because of the many interesting features it supports and it being free for anyone to use.
Still looks pretty gloopy.
We now need surfing simulators.
Fuck the water those glass physics were amazing.

Well, even if it's just as gloopy as before being able to run it on a single consumer grade graphics card without much trouble is really neat.

A little; it's not perfect water, but still quite realistic for this half of the decade.
Looks great. I remember a game which had kind of nice water phisics for it's time, you were a girl and you could use water powers to drown enemies or push them around and shit. I'd like to see a similar game done now with this technology! would be pretty damn impressive.
Now we just need a second [URL="http://www.youtube.com/watch?v=K5ZWL7aKRrA"]OE-Cake[/URL] using this and we'll be all set!

it looks viscous because the flow is slow
in other words they can't run it full speed even in that tiny box

I believe the name of the game was Hydrophobia: Prophecy, by Dark Energy Digital.
The simulation doesn't thin the fluid out (because of the fixed particle size) and it doesn't cling to anything like normal water would.
Without these factors/variables (among others) the best we're going to see is moving, frictionless gel.

Yep, that's it.
The sad thing is that Dark Energy Digital declared bankruptcy last year and had to sell all their shit off, including the engine that was used in Hydrophobia. Nobody seems to know who acquired it. It's a shame too because it would have been awesome to have seen it used in more disaster/survival games.

There's a shader used a lot in games these days that creates that effect, though. What if they set it up so that it applied that shader wherever the water touched?
When they were breaking the aquarium, did anyone else have a little fantasy about a game where you work for the mob leaning on a pet store for protection money?
This is some pretty great progress and all, but it's important to note the scale at which these are running. At it's scale it looks pretty decent and runs in real time sure, but the question is not if games would benefit from the simulation, but WHAT games show water at this scale. Cup O' Water Simulator and Fish Tank Smasher 2014?
Jokes aside, they aren't simulating ocean sized amount of water, rivers, or even ponds. While it would add a lot of immersion to be able to spill a cup of water or smash a fish tank in some AAA title, this isn't even remotely close to the scale of water seen in the Bioshock games or any sort of Sim. Hell this wouldn't even work in a really sandboxed game like From Dust.
Not trivializing the accomplishment by any means, it looks great. But this is hardly the ground breaking next step in games that show water.
is this available for download?
The amount of processing power to do that dynamically in game isn't worth it. It's cool because we're used to static bodies that we float in. But there are so few games that use water as a gameplay element simulating it isn't worth it. And if one tried to argue Bioshock 1/2 they could just make a better looking pre calculated art asset than try and simulate an ocean of water flooding Rapture using this technology given that this isn't even perfect. For the water to even accurately simulate props would have to be modeled very accurately. I'm sure many of us are familiar with HL2's buckets, appears hollow but is essentially a cylinder.
This is awesome, the only water physics simulation I have ever seen where the water doesn't look much like gel.

Sadly, even if I had such video card, this wouldn't be GPU accelerated in my case.

I think you're talking about Hydrophobia?
Looks pretty good. Also happen to notice that the music was from Mirror's Edge, but not sure which level it is.
[QUOTE=milkandcooki;40412122]any game that takes place near water
literally any game[/QUOTE]
you'd probably just be like 'hm cool' and walk on
atm this looks like another dmm - something that's impressive and super cool on a tech demo level, but ultimately isn't worth the kind of performance it demands
Well, we won't actually see this in any games for a while obviously, but in the mean time maybe they could make shaders or.. Something for things affected by water as well. Even in the demonstration, it seemed like once the water moved over something, it was the same as it was before with the water just being an object instead of, well, water. Maybe have some of the 'molecule ball' things stick for moisture if you want to do it the complicated way, or use a basic shine and stuff like Just Cause 2 does for the simple way?

Holy fuck I remember this game
If I had access to this technology I would just spend hours building tiny courses for the water to move through.
It's so hypnotic. :v:
Waterboy is another fluid physics simulator Spore was going to use.
