Abstract: Level of detail(LOD)technology is the most widely adopted technology in the model simplification of large-scale terrain,which greatly accelerates the speed of roaming terrain.Among all the LOD methods,the most popular one is LOD algorithm based on quadtree segmentation.Many domestic and foreign scholars have done lots of research work on the LOD technology.In this paper,the quadtree based LOD algorithms were sorted and summarized systematically,several key algorithms were classified and analyzed,their advantages and disadvantages were analyzed in details,and their current research status were introduced comprehensively.

Key words: Fast roaming,LOD technology,Quadtree,Terrain
