| Abstract: | Geometrical object of earth surface landscape is simulated,and stored in the memory of computer.As long as the models are visualized,the landscape after virtual modeling can be simulated.This paper mainly discusses the technologies of texture and mapping,model of LOD,dynamic multiple resolution texture,and image optimization method to enhance the representation of three-dimension model and effect of visualization. |
