山地火蔓延过程的三维模拟

本文以林火蔓延的模型为基础，运用OpenGL图形渲染的技术，考虑实时的地形坡度和风向，动态的显示实时火场边界，通过巧妙地将林火蔓延模型转变为计算机中的数据结构，结合粒子系统，在计算机上三维模拟重现了由单个火源引发的林火蔓延过程。这对于林火的辅助应急决策，有效地组织扑救，减少火灾损失，计算火灾引起的损失评估具有重要意义。

The 3D Simulation of Wild Land Fire Spread

This paper discusses the technique of simulating the wild land fire spread process based on the wild land fire spread model, using OpenGL as a graphic rendering tool kit. The simulation dynamically demonstrates the real time boundary of the fire field. By using proper data structures and particle system, we successfully simulated the fire spreading process. The factors such as wind speed and terrain slope are involved in the simulation. This technique is useful for decision--making in fire fighting and computation of the fire area in practice, and so it is of significant importance for reduction of fire losses.
