The virtual tourism teaching system of the Forbidden City is a tourism teaching system developed and produced by the author using GB3DEngine and other software. It can be applied to both tourism and teaching and even scientific research. This paper discussed the technical problems in the system construction and function setting, and the core problem of the construction is data acquisition and fine modeling. The core issues of function setting are fast browsing, information retrieval and interaction. In this paper call for the focus on openness and serving for human production among the large-scale true three-dimensional virtual reality systems.
