Interactive Fluid Motion for Particle Systems

Fluids for visual effects in interactive simulations such as video games prioritize speed and aesthetics. A suitable model for interactive applications must run fast, include artist-friendly control and interact with an unpredictable dynamic environment. This article presents a fast new algorithm that imparts fluid-like motion to particle systems and allows the fluid to interact with rigid bodies. A new nearest-neighbor tracking algorithm dynamically seeks the closest neighbors for each particle that are used to compute local interactions between vortex particles (vortons). For far-field interactions, the algorithm exploits the nearest-neighbor information to construct a hierarchical spatial partition to aggregate the influences of multiple distance vortices into a small number of super-vortons that influence all vortons. Vorton simulation combines with traditional particle system operations to provide visual effects authors with a familiar context and toolset with the additional ability to create steerable, fluid-like motion.

That tech would be sweet for driving a zombie horde

Awesome, is there a demo or something?...

This is a real advance, because the most of the apps use the GPU, and you have to have a GTX to get 60 FPS :s ...

I don´t know if it is possible yet, but it would be awesome to use the CPU and the GPU at the same time...

what does it taste like??

hey, this looks pretty cool. where can i find the paper for this?
