Research on Real-Time Visualization of Large-scale 3D Terrain.

Abstract: In view of the terrain around highway in the research area, a segment & layer based terrain LOD modeling algorithm is proposed. By combination with view-dependent factors, the complex scene of large scale terrain is simplified and the observation effect of 3D terrain visualization in research area is improved. The application of multithread processing mechanism and vision smooth transition processing enables simultaneous processing of terrain mapping and data scheduling, and improves the efficiency of terrain walkthrough and the real-time visualization effect. The experimental results show that this algorithm is featured with large amount of data processing, high efficiency and fine effect etc. [Copyright &y& Elsevier]
