摘 要:高校的人流与车流在运行过程中呈现出规律性的交通动线,表现出间歇性、流量大、规律化的特点。因此可以通过建模还原环境,进行高精度的校园交通动线实时渲染,以实现其模拟。研究中,建立了虚拟校园动线模拟系统,以辅助管理者实施动线控制与管理。三维环境细节的还原度越高,动线模拟的可靠性越高,因此三维网格精度的提升与优化至关重要。此外,动线单元的 AI 设计、碰撞体精度计算、LOD 优化均影响动线模拟的有效性。

Abstract:The flow of people and vehicles in universities present regular traffic dynamic line in the process of travelling,showing intermittent,large flow and regular characteristics. Therefore,it is possible to restore the environment by modeling for high-precision and real-time rendering of campus traffic dynamic line to achieve its simulation. In the research,a virtual campus dynamic line simulation system is established to help managers implement the dynamic line control and management. The higher the detail restoration degree of 3D environment is,the higher the reliability of dynamic line simulation is. So that it is very important that the improvement and optimization of 3D mesh accuracy. In addition,AI design of dynamic line unit,collision body precision calculation and LOD optimization all affect the effectiveness of dynamic line simulation.
Keywords:campus dynamic line system;real-time simulation;polygon optimization;AI design;LOD
