| 摘 要： | 随着城市现代化建设发展，各种市政设施管理成为人们关注的焦点。在管线信息管理系统的建设过程中，管线的三维显示成为一个首先需要解决的问题。本文从管线三维显示问题的提出出发，通过问题的细致分析，在坐标变换的基础之上，结合OpenGL技术中的坐标变换和剪切变换设计了一种能较好解决这一问题的方法，并进行了实际应用，取得了不错的效果。

| Abstract: | With the development of city modernization construction, the focus that people pays their attention on is all kinds of municipal establishment management. In the process of construction of pipe-line information management system, three-dimension displaying of pipe-line becomes too impatient to wait for solution problem. This paper combines coordinate transform and cutting transform of OpenGL technology, and designs an method which can solute the problem on the basic of coordinate transform by analyzing three-dimension displaying problem of pipe-line ,what's more, this method is applied to the practice and acquires good effect. |
