| Abstract: | This paper discusses the characteristics and the technological method of 3D scene system construction of digital city The functional characteristics of the 3D scene system of digital city are information interaction, accessibility, distribution,real time display and reality In order to meet these requirements, we use Direct 3D SDK to develop our system At the same time some key technologies on engineering construction of 3D scene imitation simulation of digital city, such as scene background changing, informational inquiry of 3D scene objects, reality of atmospheric effects and construction of 3D terrain are discussed The construction of 3D scene s ystem of digital city involves in data organization,2D to 3D conversion,and environment scene object construction At the end of this paper, a conclusion is drawn |
