Abstract

Abstract: The scientific and accurate simulation of forest fire spreading process is of great significance for disaster prevention, mitigation and relief work.Existing simulation algorithms for forest fire spread has low coupling degree in calculation of fire spread and visualization expression method, and it is difficult to visually express the calculation results of dynamic physical model in real time.In response to this question, this paper comprehensively considers the advantages and disadvantages of various fire spread models, and selects Rothermel model which is the widely used as the physical model.The Huygens theory is used to optimize the boundary points in fire evolution range and the ignition density threshold is used to control the balance between the number of seed points.Using Boolean operation to improve the calculation efficiency of multiple ignition point spread range, the fire model is closely coupled with the particle system of Open Scene Graph to complete the visual expression of fire evolution.It realized the accurate calculation and real-time, realistic simulation of forest fire spread, and provides information support for disaster emergency departments.
