Abstract

3D modeling methods of terrain,  city structure,  highway and other attached establishments are presented in detail.  Taking into account the matching of 3D object with terrain model,  the visualization processes of digital city are analyzed. 3D modeling and visualization of residential district are realized. Practical application shows that this approach has good adaptability and provides a new supplementary means for 3D visual design of digital city.
