Abstract:

Spatial pipeline is the crucial fundamental infrastructure of cities and mines, and 3D pipeline modeling and visualization is an indispensable constit uent part of the construction of 3D digital cities and digital mines, and implementing the modern management of cities. The paper firstly introduces the present situation of the application of pipelines, and discusses the data structure of pipelines and the splicing process of the adjacent pipelines. Fi nally the paper describes the system based on the techniques of Visual C＋＋ and OpenGL.

Key words: OpenGL, spatial pipeline, 3D visualization
