| Abstract: | As a multiplex system of man and nature, city is also a complex geographical entity with a high concentration of population, resources, environmental, social and economic elements. Digital City is an important application of Digital Earth. Constructing three-dimensional graphics in Digital City is one of the essential components of constructing Digital City. This thesis, starting from the aspect of technical application, synthesizes achievements in various scientific researches and briefly illustrates the technique of constructing three-dimensional graphics in Digital City. Furthermore,it puts forward some of the authors' own ideas. |
