“…Direct simulations have achieved realistic visual results when modeling the rotational motion due to the heat plume around a fire [Chiba et al 1994;Inakge 1990]. Simulation has also proved efficient at modeling the behavior of smoke given off by a fire [Rushmeier et al 1995;Stam and Fiume 1993], and the heat plume from an explosion [Yngve et al 2000].…”

In this paper we describe a system for animating flames. Stochastic models of flickering and buoyant diffusion provide realistic local appearance while physics-based wind fields and Kolmogorov noise add controllable motion and scale. Procedural mechanisms are developed for animating all aspects of flame behavior including moving sources, combustion spread, flickering, separation and merging, and interaction with stationary objects. At all stages in the process the emphasis is on total artistic and behavioral control while maintaining interactive animation rates. The final system is suitable for a high volume production pipeline.

“…Previous flame models in computer graphics include [Inakage 1989;Perry and Picard 1994;Chiba et al 1994;Stam and Fiume 1995;Figure 3: Four images from the time evolution of a level set surface using the third order DSD equations. Note that the Navier-Stokes equations are not used in this example, rather it illustrates that the cellular patterns are produced by the DSD augmented level set equations without the need for vorticity confinement or other turbulence models.…”

Figure 1: A dragon emits a flame, computed with the third order DSD equations coupled to the Navier-Stokes equations. AbstractWe model flames and fire using the Navier-Stokes equations combined with the level set method and jump conditions to model the reaction front. Previous works modeled the flame using a combination of propagation in the normal direction and a curvature term which leads to a level set equation that is parabolic in nature and thus overly dissipative and smooth. Asymptotic theory shows that one can obtain more interesting velocities and fully hyperbolic (as opposed to parabolic) equations for the level set evolution. In particular, researchers in the field of detonation shock dynamics (DSD) have derived a set of equations which exhibit characteristic cellular patterns. We show how to make use of the DSD framework in the context of computer graphics simulations of flames and fire to obtain interesting features such as flame wrinkling and cellular patterns.

Physically based modeling and animation of fire

We present a physically based method for modeling and animating fire. Our method is suitable for both smooth (laminar) and turbulent flames, and it can be used to animate the burning of either solid or gas fuels. We use the incompressible Navier-Stokes equations to independently model both vaporized fuel and hot gaseous products. We develop a physically based model for the expansion that takes place when a vaporized fuel reacts to form hot gaseous products, and a related model for the similar expansion that takes place when a solid fuel is vaporized into a gaseous state. The hot gaseous products, smoke and soot rise under the influence of buoyancy and are rendered using a blackbody radiation model. We also model and render the blue core that results from radicals in the chemical reaction zone where fuel is converted into products. Our method allows the fire and smoke to interact with objects, and flammable objects can catch on fire.
