This note discusses some of the physics and associated numerical algorithms used by Smokeview to visualize smoke and ire. Realistic visualization methods are important for applications where one wishes to observe the qualitative effects of fire and smoke rather than quantitative characteristics such as temperature or velocity. Approximations and simplifications are required to display smoke and fire at interactive frame rates. The primary approximation is to take advantage of the low albedo character of smoke allowing one to either simplify or eliminate scattering terms in the radiative transport equation used to visualize smoke and fire.
