Abstract: With the perfect of 2D GIS technology, the current research has been focusing on 3D GIS technology gradually. But there are some choke points in the 3D GIS studying at present, for example: how to create the terrain model and object model and how to achieve the real-time display in deed. Aiming to these problems and introducing the predominance of 2D ComGIS technology and OpenGL technology, then the author put forward a method which was integrating the ComGIS technology and the OpenGL technology in virtual reality studying. At the same time, the author discussed the key technology in simulating the terrain and the object, texture mapping and roam in 3D scene. Taking this method can not only hold the technology predominance of ComGIS in development, but also achieve high realistic virtual reality by using OpenGL software. As a result the system will be with a good man-machine interface, simple operation and intuitionistic display. This preliminary exploration will provide a new way in studying the virtual reality technology.
