Construction and Visualization of 3D Landscape

In order to know the operation condition before working, and reduce the risk of serious accidents of coal production industry. In this paper, by analyzing the characteristics of the environment of underground mine, using virtual reality technology, combined with the 3d Max modeling techniques and VC++ calling the OpenGL graphics interface techniques, the models are well optimized based on progressive mesh LOD algorithm for edge collapse. Using high-tech computer technology to simulate realistic mine production environment and realization of a friendly man-machine interactive virtual mine application system.
