Study on Construction of 3D Virtual Campus Based KML and Google SketchUp

Abstract

In order to solve the problem of construction of 3D virtual campus, based on 3D modeling function of SketchUp,KML language,Southern CASS and free data and platform provided by Google Earth,technological routes and detailed solving methods of constructing virtual school were researched.Taking the Yuzhong campus of Northwest University For Nationalities as an example, this paper focuses on the technical process and operation skills of building three-dimensional model, texture mapping,3D model publishing in Google Earth. It has been proved that this method has the advantage of flexibility in the construction of 3D virtual campus which has guiding significance. In conclusion, the technology road map based on KML and Google SketchUp technology for 3D virtual campus system is feasible and practical and shows advantages in the aspects of model optimization and lightweight architecture..
