Research On Some Technologies Of Virtual Environment Simulation

This paper aims at the visualization technology of large-scaled terrain model and concludes the base theory of the multi-resolution visilization technology of large-scaled terrain. Also the paper makes deep research of hierarchical model based on three-corner division and tree structure through alteration and innovation form the multi-resolution visualization algrithm proper to the large-scaled terrain, including back face elimination. The algorithm adopts OpenGL to make real-time visualization of view-dependent multi-resolution terrain model and import AutoCAD DXF document and Wavefront OBJ document reality. Provide some resolvents of the development flat of virtual reality application system. Li Ji-rong(Computer Application)Directed by prof. Zheng Gu-ping...
