Research of the display question in the 3D pipeline management information system

Good visual effect and visualization of topological relation of pipeline are characteristics of 3D pipeline management information system. So display of 3D pipeline is one of the key issues to research in the design and development course of 3D pipeline management information system. This article researches how to display 3D pipeline with good effect and at high speed using coordinate transformation and clip plane in OpenGL. The result we realize has good effect and multi-level-details characteristics.
