摘　　要：为提高大地形三维显示的效率,用LOD(Level-of-Detail,细节层次)技术对地形模型进行简化是必不可少的工作。从1996年Lindstrom等人第一次将连续LOD(Continue LOD)应用到大地形的三维显示以来,人们对大地形的连续LOD构网技术进行了大量的研究。作者结合自己的工作,从消除裂缝/T-连接、网格的剖分准则等方面对连续LOD技术进行了深入的总结和探讨。To make the three dimensional rendering of terrain more effective, it is absolutely necessary to adopt the technology of LOD to simplify the original model. Since Lindstrom, etc. firstly put continuous LOD into the practice of three dimensional rendering of terrain in 1996, large numbers of researches on continuous LOD have been done. Based on his own work experience, the author makes an analysis of continuous LOD from the following aspects, namely, the elimination of crack and T-junctions and the refinement criterion of LOD.
