"Real Time Simulation of Smoke"

Dustin Welty 2003


Abstract

This study presents a method for a stable, time efficient computer simulation of smoke. Initially the physical principles of fluid dynamics are explored to understand their relation to gaseous flow and particle interaction. Simplified Navier Stokes fluid flow equations that model smoke behavior are derived from these physical properties. Analysis of the equations occupies a large area of the study in the realization that their solution motivates the computer simulation. Issues of time and space complexity are addressed as well as the solution's stability. Finally an implementation of a particle system is discussed as a representation of the smoke. Conclusions are drawn about the performance and accuracy of the simulation.
