Abstract: This paper introduces the development of virtual Geology museum, describes some of the techniques in its implementation, such as geometry model, texture mapping and behavior model, and discusses the method how to optimize VRML file and reduce romance of the system VRML file. At last, a vivid virtual three-dimension museum is constructed on Web.
