Liquid fun (2014)
- emsy 9y agoThis project is 3-4 years old and the last commit was 2 years ago.
- shadowmint 9y agoBy comparison Box2D is actively maintained: https://github.com/erincatto/Box2D/commits/master https://github.com/erincatto/Box2D/commits/master This is the problem when you fork a project. :/
- dang 9y agoOk, we'll split the difference and call it 2014.
- aerovistae 9y agoI can't wait til this sort of thing is common in 3D.
- slavik81 9y agoIt's brutally expensive, unfortunately. Moving from 2D to 3D you go from needing O(n²) particles to O(n³) particles to fill a box. That's an awful increase in complexity, and it really limits the size of what you can do. With that said, NVIDIA has a boatload of money, top-notch hardware skills and fluid simulation experts like Matthias Müller-Fischer working on the problem. NVIDIA Flex[1] is amazing to behold.

- pbhjpbhj 9y agoAs a slight aside, is NVIDIA's motivation profit from the gaming industry or does this find industrial application outside of the obvious visual presentations?
- TeMPOraL 9y agoPossibly, given that - besides all that recent neural-networks-on-GPU craze - people run e.g. CFD simulations on GPUs. I recall SpaceX in particular doing simulations for their rockets on NVIDIA hardware. https://blogs.nvidia.com/blog/2015/03/17/mars-rocket/ https://blogs.nvidia.com/blog/2015/03/17/mars-rocket/
- slavik81 9y agoFlex, PhysX and Gameworks are all meant for games, but I would suspect that the game physics talent helped guide CUDA, which does have a lot of industrial applications. They aquired Müller and PhysX when they bought Ageia in 2008. They changed Ageia's direction away from developing dedicated hardware (a Physics Processing Unit) to instead leverage the GPU for physics calculations.
- jacobsimon 9y agoEven better in 3D: http://david.li/fluid/ http://david.li/fluid/
- santaclaus 9y agoOhhh old school, FLIP was fun! David should upgrade to APIC.
- kevinwang 9y agoThe performance of this on my laptop invariably blows my mind
- bsenftner 9y agoI like this version more (also david.li): http://www.adultswim.com/etcetera/soup/ http://www.adultswim.com/etcetera/soup/ (2D, but funnier)
- abainbridge 9y agoNice. Is there anything like this for simulating gas? I want to make a 2D simulation of an internal combustion engine.
- ino 9y agoperhaps not quite what you want, but you can do this with box2d: https://www.youtube.com/watch?v=8kZRpouZ3OQ https://www.youtube.com/watch?v=8kZRpouZ3OQ
