摘　　要：实时人群运动仿真系统通过虚拟现实技术,可在计算机中交互式地显示人群在指定场景中的运动状况.通过对人群设置不同的全局运动路径,可以模拟人群的不同行为,例如人群的集会、疏散、逃生等情况.故该技术可应用于应急疏散演练以减少事故的伤害甚至能发现并解决建筑在设计时可能存在的安全隐患等.目前,常见的人群运动仿真系统往往只能在单一操作系统下执行.随着计算机硬件和移动设备的发展,跨平台的仿真甚至在移动设备上进行人群仿真成为新的需求.本文提出了跨平台的实时人群运动仿真系统的系统架构,通过解析并处理C3D文件实现了人体动作,并通过Mono Game平台实现了跨平台的实时人群运动仿真.Real-time crowd simulation system can display the crowd motion interactively in the specified scene according to virtual re- ality technology. By setting different global motion paths for the crowd, different behaviors （e. g. , crowd gathering, evacuation, es- cape ） can be simulated. Thus,it can be applied to emergency evacuation to reduce risk of accidents. Also,it helps to find out and ad- dress the public safety issues in architecture design. Most of the current crowd simulation systems can only be executed in a single op- erating system. However, the development of computer hardware and mobile equipment leads to a new demand for cross-platform sim- ulation system even simulation system on mobile device. This paper presents the architecture of the cross-platform system for real-time crowd simulation. The system can simulate the human motion via analyzing and manipulating C3D files and it can simulate the crowd motion in real time base on MonoGame.
