基于OGRE的应急火灾仿真研究及实现

Research and implementation of OGRE-based emergency fire simulation

从粒子系统的基本生成步骤、粒子系统在OGRE中的调用方法等方面介绍OGRE粒子系统原理。结合给定火灾案例创建楼房3D实物模型,根据楼体、灾情和环境等实际情况定制着火路线、着火点、燃烧中心等实验数据,通过火灾受力分析、布控着火点、烟的布控等步骤在OGRE中完成了火灾的仿真实验。实验效果证明该仿真方法是可行和有效的。

The principle of OGRE particle system was introduced in points of tl^e basic generation steps, and calling the particle system in OGRE. Based on a specific fire disaster case, a 3D building module was established. Then, according to the real sit- uation of the building,accident, and environment, data such as the fire route, fire source and combustion center were decided.Through stress analysis of the fire, fire source setting and smoke dispatching, the fire simulation was carried out in O- GRE. The simulation results showed that the simulation method is practicable and effective.
