A new method of tunnel 3D modeling and its applications

3D modeling of tunnel is an important research issue with the studying of the digital mine in China. In view of the deficiencies of present modeling methods, a new method named tunnel component is presented. The method mainly includes three steps: a) generate tunnel centric line model; b) create double line tunnel model; c) construct 3D tunnel model. In order to improve the flexibility and the interactivity of 3D visualization, a 3D interactive environment is provided. The application for 3D tunnel modeling and 3D visualization including 3D interactive visualization, aided design and spatial inquiry etc are introduced. A real-3D geosciences modeling system, GeoMS3D, is developed with VC++, OpenGL and SQL sever. An actual 3D tunnel model of china is shown as a case.
