基于复合虚拟力场的大规模人群行为模拟

Simulation of Massive Crowd Behavior Based on Composite Virtual Force Field

以类鸟群(Boids)系统为基础,提出了一种基于复合虚拟力场(Composite Virtual Force Field)的大规模人群行为模型。该模型将类鸟群系统中三个基本规则的作用抽象成类似于物理学中的三种矢量力,同时为了表现出个体之间的远近关系,我们又加入群体力的作用,从而实现了在虚拟环境中大规模人群行为的仿真。实验结果表明,在复合虚拟力场控制下的群体行为模型能够逼真合理的模拟出现实中大规模人群的多种行为。

With Boids as example, a model of massive crowd behavior was built based on composite virtual force field. This model abstracts the three basic rules of Boids as three virtual forces, and for relationship between each individual, the effect of group force was taken into account. Using composite virtual force field, the model could generate real-time crowd behavior in virtual environment when the model ran. The experimental results indicate that this model can simulate many crowd behaviors under different circumstances really and reasonably.
