Automatically Generate Three-Dimensional Pipelines Based on GeoDataBase MultiPatch Model

Abstract

With the development of city, the scale of underground pipeline is always extending and to solve the problem of virtual underground pipeline generation is extremely urgent. In this paper, we will use the triangular slice to establish three-dimensional MultiPatch models. The three-dimensional vector will be used in this new modeling method of 3D visualization of underground pipeline. The method can automatically deal with elbows or straight pipe modeling problems. And we find it suitable for rapid modeling and wide range of applications through our series of test.
