一个经典的roam算法 打开后可见包围盒,网格细分 体现了lod of detail-roam a classical algorithm can be seen surrounded After opening the boxes, Mesh Subdivision reflects the pedigree of detail

四点细分算法 VC++程序源码； 某人的论文源码，经我修改用于生成中国地图的细分效果图,4:00 subdivision algorithm VC++ Procedures source a person s thesis source, after I have altered the map of China used to generate the effect of the subdivision plan

常见的差值算法，简单剖分算法，以便让初学者很快入门-Common difference algorithm, a simple subdivision algorithm to allow beginners started quickly

OSG中通过LOD节点来实现多细节层次显示，此处用了2个不同的图像来举例，实际应该是同一图形的不同细分图-OSG through the LOD node to achieve multi-level level display, here with two different images for example, the actual should be the same graphics of different subdivision
