Unity3D应用于疏散仿真的问题与前景

Problems and prospects of Unity3D applied on evacuation simulation

为探索Unity3D作为虚拟现实工具应用于疏散仿真领域的可行性,以某高校办公楼为载体,结合MassMotion和Pathfinder两款商业化软件的模拟结果,对Unity3D的疏散模拟效果进行对比分析。研究发现,Unity3D内嵌的疏散模型基于A*的导航网格寻路算法,通过对人物模型参数的合理取值,嵌入人物运动、销毁等脚本语言,能很好地模拟疏散过程,获得近似商业疏散软件的仿真效果。Unity3D还能借助渲染脚本,调入火灾模拟软件FDS的烟气仿真结果,配合虚拟现实技术的头戴式显示产品,实现对逃生场景的沉浸式体验。

To explore the feasibility of using Unity3D as a virtual reality tool in evacuation simulation, taking the office building of a university as an example, combining with the simulation results of two commercial software, MassMotion and Patfinder, a compara? tive analysis of evacuation simulation results of Unity3D was carried out. The results showed that, Unity3D embedded evacuation model based on A* navigation grid routing algorithm can simulate the evacuation process well by reasonable value of person model parameters, and by embedded scripting languages such as charac? ter movement, destruction, etc. It’s simulation effect is similar to the commercial software. In addition, Unity3D can also use rendering scripts, import the smoke simulation results of FDS, implementing immersive experience of escape scene combining with headwear display products with virtual reality technology.
