Complex Dynamics, Evolution, Separation, Profile Modeling of Fire in 3D for Computer Animation

In this paper, we present a system for modeling fire dynamics with emphasis on realistic behavior and spread as well as the extensive behavioral control system. Our system provides a wide range of parametric and procedural controls. Flame spread and motion is achieved using differential equations which take account of wind, buoyancy, diffusion and velocity of the burning surface. Realistic behavior is achieved using stochastic models of flickering and buoyant diffusion. We also implement wind fields for additional controllable motion. Flame behavior covers moving sources, flickering, separation and merging.
