| Abstract: | It is one of the hotspots to construct the stereo scene model of three-dimension digital urban for the geographical information system technology at present.According to the characteristics of geographical information system,the restriction of actual computer hardware level and the existing three-dimension visualization technique,this article researched the key problems such as modeling of three-dimensional city,the dynamic attemper of the vass data,quick display,real interaction of three-dimension and networked expanding and so on,put forward the solution to realize the urban three-dimension visualization and the dynamic roam of large range cityscape. |
