This could be the future of water in games

PBF Water Demo 580x300

By on April 26, 2013 at 8:39 am

Nvidia programmer Miles Macklin is working on a new PhysX solution that could transform the way water behaves in games.

In a video posted by GamesHQMedia, Macklin has used a new Position Based Fluids technique to realistically model the ebb and flow of liquid as it rushes around static objects like columns or reacts to external stimuli like contracting walls. Perhaps most critically, the video accurately demonstrates the way a small body of water will behave in the presence of rabbits and werewolves. The demo is running on a GeForce GTX580.

Noting that existing methods are “computationally expensive”, Macklin is aiming to create a more efficient real time solution.

Macklin is no stranger to the world of games, having worked for LucasArts, Rocksteady and Sony in recent years.

When I saw that yesterday it truly impressed me. I hope we get to see this in future games.


Woah, that is super impressive! Finally, realistic simulated water! I look forward to taking a quick look at it in action, and then turning it off to return to some semblance of a usable frame rate.

In all seriousness, it’s amazing that the demo is running on a GTX580. It’ll be interesting to see how well systems perform when also trying to render complex lighting and particle effects, high res textures, and large scale scenes.

If nothing else, it bodes well for water simulations in cinema special effects.


It’d be cool if they could turn into one of their downloadable tech demo’s that we can play around with to show off our gfx setups!


Jason Imms,
I’m imagining 2015+ before we would start to see this in high-end games due to the fact that the lighting for it seems a bigger problem than the simulation.

I just hope it’s not nvidia exclusive again.


This bodes well for bikini car wash games in the future…


Yeah this was pretty epic, won’t be seeing it in games for a while though sadly.


It is a start though. I can’t wait for the first wave of games boasting it as an option…although it will probably be abused and overused until developers learn to dial it back a notch, so maybe I’m really looking forward to a year or two after?


WOW! That’s running in real-time on a GTX580?

That looks superficially like computationally intensive CFD.


I could spend hours just playing with the demo software. Looks so much fun.
Can’t wait to see it in game!



You could always just put a rabbit in a bathtub and watch the realistic water effects.


interesting that they only show such small scale, gottas wonder if rendering like that is viable on a large scale

Won’t be that long and you don’t need PhysX to do it either ;) Pretty impressive demo, nonetheless. Much more impressive than the destruction one released at GDC.
