摘要
林火仿真研究中,为更好地描述林火行为,以辅助扑救决策,林火的蔓延模拟已经成为重要的研究课题。选用Rothermel林火蔓延模型,结合实际林区的地理环境,提出一种基于OGRE粒子系统的林火蔓延模拟方法,给出了利用OGRE进行林火蔓延模拟的过程,并在计算机上重现了由单个火源引发的林火蔓延过程。
For better describe forest-fire behavior to support saving decision in the forest-fire simulation research,the forest-fire spread simulation has become an important research subject. Choosing Rothermel forest-fire spreading model and combining with the forest region geographical environment, a kind of forest- fire spreading simulation method was proposed based on the OGRE particle system, the process of forest- fire spreading simulation was showed by the OGRE ,and the forest-fire spreading process caused by a single fire was reproduced in computer.
