An Efficient 3D R-tree Extension Method Concerned with Levels of Detail
Levels of detail (LOD) is the key feature of 3D GIS. Aiming at the critical issues of LOD models organization, this paper presents an extended dynamic 3D R-tree structure concerned with LODs, which improves existing node-choosing and node-splitting sub-algorithms. In the node-choosing process, a glo...
