摘要:

采用智能体(Agent)方法研究虚拟人在行走时与虚拟环境人行天桥之间的交互性。利用改进后的AStar算法计算智能体的行走路径、使用预先计算的导航图对路径进行寻找,通过基于几何方法的碰撞检测来确定虚拟人在人行天桥行走时的正确位置,实时驱动虚拟人并使之对周围环境的感知。仿真结果表明,该方法能直观地展现人行天桥上人群运动的过程,对现实中的人群运动分析有一定的指导意义。

Abstract:

This paper adopts the method of Agent to study the interactivity of virtual human in virtual environment pedestrian bridge with walking.Improved AStar algorithm is used to compute the Agent of walking paths,precomputed navigation is employed for looking the right paths and the collision detection of geometric method is adopted to determine the virtual man's correct position in the pedestrian bridge.The virtual man is driven in real-time to perceive the surrounding environment.The results of simulation show that the process of pedestrian bridge crowd movement can be displayed visually,which can offer valuable references to real crowd movement analysis.

Key words: crowd simulation;three dimensional animation;collision detection;virtual man
