Cocos2d SPH particle fluid dynamics with box2d interaction
Port of ElectroDruid's C++ SPH implementation found on box2d forums. Link: http://www.box2d.org/forum/viewtopic.php?f=3&t=574&start=70
iPhone 4 can run this 60fps with 500 particles.
This demo is not working that well as the original version. I couldn't get the verlet version stable enough, so it's turned off. Euler integration have problems in interactions with box2d dynamic bodies.
