Fire Simulation in 3D Computer Animation with Turbulence Dynamics including Fire Separation and Profile Modeling

Jozef Hladký, Roman Durikovic

Abstract


In this paper, we propose a system for modeling fire dynamics with emphasis on realistic behavior as well as the extensive behavioral control system. We propose a wide range of parametric and procedural controls. Simulation of flame spread, and motion is governed using differential equations which takes into account wind forces, buoyancy forces, diffusion and velocity of the burning surface. We propose to enhance the realistic behavior by using stochastic simulation of flickering and buoyant diffusion. The proposed wind fields serve as added fire motion control by a user. Flame behavior covers moving sources, flickering, fire separation and fire merging.
