Real-time rendering of landscape has attracted growing interesting in recent years. The existent accelerating methods of 3D terrain rendering have made their contributions to terrain visualization

but

they have themselves drawback

especially for large scale terrain visualization at interactive rate. Large scale terrain visualization contains the following contents: terrain multi-resolution representation

terrain and texture paging

terrain and texture LOD control and efficient data store and retrieve. Based on the research about management and real-time rendering of large scale terrain data

one method of generating multi-resolution terrain model is improved

which combines the representation of terrain multi-resolution model with view-dependent control. A new method of storing and retrieving terrain data by quadtree is proposed. Furthermore

an all-in-one terrain visualization system which integrates adaptive triangulation

dynamic scene paging and data updating is realized. At last

some experiments have been presented to verify the work done in this paper.
