为了加快对三维可视化中海量数据浏览的速度 ,提出了分区漫游的思想 。
3D visualization is developing quickly in recent years. When 3D data are much greater than 2D data, it is a big problem when wander in a virtual 3D world. This paper proposes district wandering techniques that can fast the speed of wandering. District wandering is similar to LOD technique, which is also used to decrease the amount of 3D data amount. LOD has to build at least 2 versions for every object, so it increased the file size at the same time. District wandering does not increase file size, but tries to simplify the 3D scene by showing or hiding objects according to the district.
