A Survey: Technologies of LOD in Virtual Environment Generation

GUO Yang-ming, ZHAI Zheng-jun, LU Yan-hong (College of Computer Science, Northwestern Polytechnical University, Xi'an Shanxi 710072,China)  
Virtual reality technology makes participants feel highly lifelike “ reality ” with its key technology. The present computer graphics, so long as having enough time, can produce accurate computer picture, but the generation of the virtual environment needs the real-time character of the figure, so, it has to reduce geometry complexity of the virtual environment and picture quality, or adopt other technology to improve the lifelike degree of the virtual environment and the generation speed. This text introduces the choice and production of LOD model in virtual environment generation, analyses the typical model generation algorithms and existing problem, and indicates its future research direction.
