摘　　要：针对不同轨道线路的线形特点,通过线路中心线数据计算轨道截面关键点的空间信息,以OpenFlight API为基础编程,实现轨道线路三维模型的自动生成。建立地形模型并在轨线合适位置放置车站、信号机及编组机车,沿线布置树木和建筑模型,搭建成逼真的城轨电子沙盘。This paper calculated spatial information of the key points on the track cross-section based on the centerline data firstly according to the shape characteristics of the different rail lines,then created the models of track and tumout automatically by programming in the basis of the relevant spatial information and OpenFlight API.The electronic sand table for the Urban Transit could be implemented by creating the terrain model,placing the stations,semaphores,train at the appropriate position,laying some trees and buildings along the line.
