摘要： 线路是由诸多构造物组成，构造物的三维景观仿真是线路整体三维景观仿真的重要组成部分。针对OpenGL建模能力不强的特点，提出了基于外部3DS模型的线路构造物建模方法。基于Visual C++和Oracle数据库建立了构造物模型库，实现了对模型的有效管理。解决了构造物模型与线路三维场景精确匹配与控制问题，实现了构造物模型在线路三维景观仿真中的应用，建立了具有较高真实度的线路三维景观。

Abstract: The lines (or road-lines) are formed by many structures, so the structures’ three-dimensional landscape simulation is an important part of the line landscape simulation. OpenGL modeling capability is not strong enough, so the new line structure modeling method is proposed based on external 3DS models. The structures’ database is established and an effective management of the models is achieved based on Visual C + + and Oracle database. The problem of exactly matching and controlling between structure models and line three-dimensional scene is also solved, and then high reality of three-dimensional line landscape is reached.
