Terrain Data Stream Transmission Strategy Based on Visibility Clipping

In order to realize real-time transmission and effective display of the terrain landscape data,based on the requirement of different view field of high altitude and surface,this paper presents a terrain data stream transmission strategy based on visibility clipping,it can efficiently determine the visibility of view field and the Level Of Detail(LOD) of key node when position of vision moving.Experimental results show that the terrain data processed by the server can be rapidly transmitted to the client for accurate display.
