Forest Fire Spread Simulation and Fire Extinguishing Visualization Research

There are three main types of forest fires: surface fires, tree crown and underground fires. The frequency fires accounts for more than 90% the overall In order to construct an immersive three-dimensional visualization simulation various fire ignition methods, spread, extinguishing exercises studied. This paper proposes a lightweight spread method based on cellular automata applied virtual 3D world. By building plant model library using cells express different plants, by geometric plants truly capture combustion process single plant, we can further simulate forest-scale propagation analyze factors that affect spread. addition, constructed scene, this study explored forms methods in environment, mainly liquid flame retardants such as water guns, helicopter-dropped retardants, or simulated rainfall. Therefore, occurrence, be visualized after interactive is designed implemented. Finally, greatly enhanced immersion realism scene simulating changes materials during fire.
