The virtual campus is the concrete application of the virtual reality technology in the digitized campus. Through the virtual campus, people can visit and plan the scene of real campus on the computer. By combination of 3D and virtual reality, the study achieved the reaming of the virtual campus of the China University of Geosciences (Beijing) and the interior of some construction based on the 3ds Max and Virtual-Reality Platform and discussed the key technology. In the future, the study will in real sense lay the foundation for building the ground-and-underground 3D simulation.
