On Underground Power Planning Based Virtual Reality

With the development of city, the planning of underground power pipelines becomes more and more important. The layout is difficult because pipelines situate underground. They are invisible and related with many factors such as roads, buildings, transformer substations, other pipelines and so on. In order to improve planning efficiencies, a new technique based on virtual reality is presented. Firstly, a virtual scene is constructed according to the existing pipeline and related environment. And the area partition method is introduced to increase rendering speed. So the designer can browse the virtual underground space at their choice. It makes the planning work simple. Then, a planning drawing and a three-dimensional demonstration will be automatically produced on the basis of the planning message. When the technique was applied to power planning of Pudong District in Shanghai, China, it saved planning and lay out time about 20%.
