On Real-Time Modeling of 3D Terrain Database

Abstract:

With the uprising deployment of large-scale environmental simulations, as well as the wide applications of the GIS data in the simulation models, the traditional modeling methods have been difficult to meet the requirements of terrain generation of large areas. In this paper, we study a new terrain database modeling process based on Celerity/TerraVista, which uses the techniques of image compression, block optimization, and level of detail (LOD) , for terrain generation of large areas. Tis new modeling process has been applied in our independently developed simulation system and has achieved good results.
