ABSTRACT:
FIELD OF THE INVENTION
This invention relates to simulating use of nozzle spray to combat hazardous conditions in emergency situations, such as when performing firefighting, with real-time computer graphics, including the use of particle systems.

BACKGROUND OF THE INVENTION
In a simulation, flow from a nozzle should affect airflow in an environment and cause motion of aerosols and gases to be affected. In the preferred embodiment of this invention, a firefighter training simulation, extinguishing agent flow from a nozzle should affect the path of a fire and smoke plume. This invention simulates such an effect with considerably less computational cost than a computational fluid dynamics (CFD) simulation, allowing for real-time simulation. This invention also applies to graphical components other than fire and smoke, including ambient steam, ambient smoke, visible fumes, invisible fumes, and other aerosols, gases, and particulate matter.
