A New Way To Render Water In Games
Two researchers at graphics chipset manufacturer Nvidia have released video of a new method of simulating fluids. You’ve never seen dynamic water like this.
These two videos demonstrate the concepts behind a paper to be presented at SIGGRAPH (a development conference for the technical aspects of computer graphics) by Miles Macklin and Matthias Müller-Fischer.

Based on our understanding, this research is close to the cutting edge of programming techniques. You won't be seeing this water in a game any time soon, but it could feasibly work on the PlayStation 4 and next Xbox since the simulations were run on a single Nvidia GeForce 680 GTX graphics card – which is broadly similar in power to the video hardware the next consoles will be shipping with.
From the paper’s abstract:
In this work we present an iterative density solver integrated into the Position Based Dynamics framework (PBD). By formulating and solving a set of positional constraints that enforce constant density, our method allows similar incompressibility and convergence to modern smoothed particle hydrodynamic (SPH) solvers, but inherits the stability of the geometric, position based dynamics method, allowing large time steps suitable for real-time applications.
What he said. That water sure looks pretty, doesn’t it?

I’d like to ask you to support Game Informer’s continued coverage of games with a subscription. For less than two dollars per issue, we mail you a full year of 10 print magazines, each with cover stories and preview features filled with exclusive details about the most exciting upcoming games. We profile and interview game creators. We look back on the rich history of gaming, and we celebrate what’s next.
Here on the website, we offer much of our content for free, including game reviews, daily news, videos, event coverage, and more – all with minimal ads.
We do so with a small editorial team, alongside contributing paid writers from around the world – over 65 individuals from 9 countries around the world, just in the last couple of years.
It’s not possible without support.
In a time when game makers and games coverage have faced hard struggles and layoffs, the future of this 30+ year magazine and community is at risk. Our new standalone magazine subscription is the number one way you can keep us alive – and we believe you’ll get a pretty fantastic gaming magazine in your mailbox every few weeks for your trouble.
Thank you.
