EAST's inner structure is very complicated and contains a lot of subsystems which have different functions. The virtual EAST system aims to establish an EAST virtual reality scene in which the user can roam and access to information by interacting with the system. In order to facilitate the development of different systems' need, a variety of formats and types of device model are produced in the preprocessing stages. Besides, related parameter information, diagnostic information and magnetic measurement information are stored in MySQL database. The virtual EAST system's developers use and maintenance the model and data together. Therefore, in order to promote mutual cooperation of developers and avoid a collision from disoperation, it is necessary to establish a system to efficiently use those models and a unified entrance for viewing and managing models and data.
