摘要
在环境污染应急系统中,实时模拟污染气流扩散场景是制定污染事故应急措施的关键。为兼顾模拟的实时性和逼真性,利用离散化的思想,提出了一种基于粒子系统的简单快捷的数学建模方法,实现了对污染气体排放现象的建模,并在此基础上设计了一个污染气流的生成算法。最后给出了污染气流扩散的动态模拟效果图。
In the environmental pollution emergency system, to simulate the scene of the polluted airflow emission in time is the key to set down the scientific measures to polluted accident. In order to satisfy the requirements of real-time and reality in the simulation, a fast and simple mathematic model based on particle system is proposed applying discrete idea, and then a model for polluted airflow emission is established, Based on the model, an algorithm of generating polluted airflow is presented. Finally, the dynamic simulation graphics are shown.
