Demo of ofxMSAFluid addon for openFrameworks, a C++ Jos Stam fluid solver. Source for the demo is included with the addon, and includes tuio support.

Info and source at memo.tv/ofxmsafluid

Java / Processing version at memo.tv/msafluid_for_processing.

Many thanks to Maa (lagraine.com ) for some serious optimizations.

Next version will be openCL ;)

    Hi Memo,

    How did you work around Jos Stam's patent? We started a project at work based on his solver but had to start over after we ran into some patent issues.

    Here's a link to our project: software.intel.com/en-us/blogs/2009/02/05/kaboom-multi-threaded-fluid-simulation-for-games/

    Hi Omar, what kind of issues did you run into? The patent is quite vague google.com/patents?id=ySgIAAAAEBAJ and seems to be covering solving cell based fluid simulations in general. Secondly Jos Stam mentions that he has seen this method discussed as far back as the 50's. Finally for non-commercial projects I can't see it being an issue (but of course I'm no lawyer). For a large scale commercial project I guess one would always have a lawyer (I take it you work for intel?. And as a side note, gpgpu is the future! http.developer.nvidia.com/GPUGems3/gpugems3_ch30.html

    Hi Memo,

    I do work at Intel in Portland, OR, USA. My team's main focus is games and I'm no lawyer either :). We had issues with our legal department approving it and getting in touch with Jos Stam turned out to be quite difficult for some reason. For the project I linked above, one of our goals was to release all code for a multi threaded 3D fluid simulation. We found several 2D simulations out in the industry and but not much in the 3D space. The project was based off Mick West's Practical Fluid Mechanics cowboyprogramming.com/2008/04/01/practical-fluid-mechanics/. We'll be releasing the code in the next week or so if you're interested in getting your hands on a 3D threaded fluid simulation.

    definitely, sounds ace. can't wait to run it on my 8-core ;) looking forward to it...

    Hi Memo,

    Our project has been released: software.intel.com/en-us/articles/multi-threaded-fluid-simulation-for-games/

    It's an article explaining our work with download links to source code and binaries at the bottom. Let me know what you think or feel free to post a comment on the article :-)
