Fluids v.3 is a large-scale, open source fluid simulator for the CPU and GPU using the smooth particle hydrodynamics method. Fluids is capable of efficiently simulation up to 8 million particles on the GPU at interactive rates. Fluids v.3 presents an improved solution to the fixed-radius nearest neighbor search problem.
The goal of Fluids v.3 is to enable next-generation software for motion picture production, media arts, and interdisciplinary research. Most modern software for fluid simulation relies on CPU-based, classical techniques for high quality results, yet take days or weeks for a single simulation. This limits their use to motion picture production in high end studios. To enable digital arts, interactive installations, and the democratization of filmmaking, visual effects must be accessible to the individual artist both in cost and performance. To move toward this goal, Fluids v.3 is fully open source, and utilizes low-cost GPU hardware to simulate large scale effects in real time.
The techniques of Fluids v.3 have been incorporated into Bullet Physics, and open source physics engine used in major motion picture and independent films. Fluids v.3 has also been adopted by researchers in physics, hydrodynamics, geology and astronomy.
Novel methods for fluid simulation were presented at the GPU Technology Conference, in Santa Clara, CA. The new Fluids v.3.1 can simulate over 4 million particles at 4 fps, is easier to build, and runs on CUDA 5.0 and 5.5.
This January, 2013, I start a new position in Graphics Research at NVIDIA Corporation in Santa Clara, CA, working with CAD clients to develop GPU technologies, and exploring topics in computer graphics.
