Awesome: Real Time 3D Fluid and Particle Simulation and Rendering

This application uses a GPU based 3D fluid solver to simulate the turbulent wake behind a car. The simulation based on CUDA / APEX (Adaptive Physics EXtensions) allows to move hundreds of thousands of particles (500,000 in the video). After simulation, the particles are sorted using a GPU-accelerated sort, and then rendered as alpha blended sprites with motion blur and volumetric shadows.
