Abstract
On base of concept characteristics analysis of digital mine, applying GIS technology, graphic technology, visualization technology, animation technology and database technology, and combining with Visual C++6.0 and OpenGL, a simulation system of digital mine was established. On the basis of analyzing scene walkthrough, interactive control and function of collision detection, this paper put forward detailed frame procedure of simulation system of digital mine, that is data acquisition, 3D data structure, 3D model, 3D visualization of the output. By using instance technology, texture mapping, real-time visual generation technology and level of detail techniques, four functions were designed in this system, including virtual scene of digital mine, visual spatial information for decision-making and dynamic visualization of production. It were realized that the automatic and controllable walkthrough of virtual scene, interactive control and collision detection use OpenGL. The realization of this system has an important significance for the works, such as optimizing mine design, demonstration of technical schemes, and training of minerpsilas safety and rescuer work of accident.
