With the continuous development and deepening of GIS (Geographic Information System), 3D visualization, virtual reality, 3D Internet and other technologies, people can not only use computers to process graphics, images, videos, sounds, animations and so on. It can also express three-dimensional entities and three-dimensional environments in the form of virtual reality, and generate interactive three-dimensional animation and dynamic simulation. Therefore, many virtual reality systems have appeared one after another, such as virtual tourism, virtual city, virtual transportation, virtual school, virtual bank, virtual business and so on.
