3D Visualization of Large DEM Data Set Based on Grid Division
In this paper，a real-time LOD division method based on grid division is developed．Based on raster characteristics of DEM and image data，this method uses a simple geometric algorithm to implement the dynamic DEM data delamination．It costs much less calculation time，and could obtain fast visualization and animation of large DEM data set．
