Research on Constructing 3-D Pipeline Connection Model By Using OpenGL

3-D modeling and visualization of pipeline is an indispensable and important component that constructed digital city and implementation of pipeline management information system. This paper describes the basic steps that constructed 3-D pipeline connection by using the initial points set, and especially discusses the key issues of constructed the 3-D pipeline complexity connection by using OpenGL. At last, the author proved the theory mentioned in this article by experiment, it shows that 3-D geometric transformation and datum plane rotation can realize the visualization of 3-D pipeline complexity connection efficiently and conveniently, and this technology have achieved good effect in the practical application.
