Visual Simulation of Smoke and Fire
The visual simulation of complex natural phenomena such as smoke and fire is a challenging and important problem in computer graphics. Applications range from adding special effects to movies to enhancing the look and feel of video games. In this talk I will present different techniques to simulate the motion and appearance of smoke and fire. My approach is based on the physics of fluid flow, namely the Navier-Stokes Equations. I will present a stable numerical technique which solves these equations. Stability allows the simulation to be advanced at any time step, which results in faster animations. Using these techniques animators can, for the first time, interact in real time with smoke and fire.
