Vortex: Simulated Fire Whirls
VORTEX: SIMULATED FIRE & SMOKE
Vortex is a fluid simulator for fire and smoke written in C++ and DX Compute. Vortex solves the Navier-Stokes fluid equations of motion using Jos Stam’s stable fluids method, and the MacCormack method for detail preservation. The simulator runs entirely on the GPU, with interactive rates up to resolutions up of 1024^3 at 20 fps.
A volume raycasting engine renders the fluid as a final image, also on the GPU, by sampling the volume. The raycaster supports a piecewise-linear function to allow arbitrary transfer functions that enable a wide range of visualization options from fire, to smoke, to oily clouds.

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.
