NVIDIA PhysX Demo Features Fluid Physics, Bunnies

Water effects and fluid modelling has long been one of the holy grails (and stumbling blocks) of gaming graphics, and NVIDIA have released a new video to show off what their GeForce cards can do. The footage is ostensibly real-time, running on a single GFX 580 card, and is eerily reminiscent of what happens when you open a Borderlands 2 toilet with PhysX enabled.

Nothing too profound, but a fun showcase for a sunny Thursday afternoon nevertheless.

Demo is ok. So they've got good looking water to wrap around one single static object. Thats ok. But in game we want multiple objects, bullets and explosions and everything. Sadly, I imagine that if they are promoting that this demo ran on a single GtX580 we are a long way from seeing mainstream usage of water to the degree that I mention.

On top of this, you need to factor in game devs. Just because the hardware can doesn't mean that the game will. Crysis 3 has some water effects that they were proud of but that doesn't use physx.

I agree, the demo us a bit meh, but, what is great is that NVIDIA are continuing to support and expand PhysX. They could have just bought the company and got rid of it like many things, but they are expanding on it.

Modelling fluids is incredibly complicated. Have a look into what's involved in computational fluid dynamics. What they're achieving in this, making water react to an object in a realistic manner, is actually very impressive from a technical perspective.

@GPG: My thoughts exactly. We're not a tech site, but I was impressed at how this could potentially be leveraged into games going forward.

Just wow... much better than previous implementations.

The good thing about this being done by Nvidia is that the game devs now dont have to do all the donkey work.

I have seen loads of games benefit from similar features in the past (Barrel of water in Sherlock Holmes vs Jack the Ripper to name just one) and the better these features are and the more there are of them, the better all games will look.

Going to see loads of this stuff this year I think, with the coming "next gen". BRING IT!

Well it looks good but I can't think of a single situation where I have been in a game and thought "These poor fluid dynamics are really spoiling this game"

Although I haven't played Beachcomber 4 yet.

You haven't? You've never played a game and thought "that looks a bit crap".

You've never played a game that was looking graphically amazing for its time, only to spot the waves in the ocean working completely on a pattern and thinking that it looks really unreal and stupid?

I have, I like good visuals. While poor visuals wont always ruin a game... if this means that it is easier to have amazing visuals but for less work, then why not. What is there to lose? Win-Win.

I'm more excited about how this could potentially factor into gameplay. Shiny visuals are lovely (don't get me wrong!), but imagine how improvements in fluid physics/modelling could lead to exciting new puzzlers, combat, exploration - hell even a remodelled GES BioRifle.

That would imply that the game would have to have PhysX hardware support. I assume ATI cards would not have this?

I kinda see all these advances as cumulative, just another step towards bigger and better games. But yes, PhysX is NVIDIA's baby (though it's possible to do some clever driver trickery on some ATI cards AFAIK).
