Abstract: For the advantages such as large information capacity, multi-directional demonstration, vivid simulation and fully immersive, virtual exhibition hall is widely used in fields of exhibition, publicity, education and etc. However, difficulties of modification, poor reusability and generality are obvious defects of conventional virtual exhibition hall, so we put forward a new design method which enables users to customize virtual exhibition hall by using reserved interfaces, these interfaces provide user access to configure the exhibition hall models, exhibits and descriptions etc.In this way, users could get what they want by offering parameters and manual settings. In the paper, we firstly analyze the functional requirements of the system, secondly give the corresponding module divisions from three levels, bottom, middle and high. Then we give detailed overall framework of the system, and meticulously illustrate the solutions of technology problems that we met. Finally, the virtual exhibition hall could be produced according to the user’s configuration without modifying the program. The system increases the generality and reusability of the virtual exhibition hall, which benefits promotion and development of the virtual exhibition hall.

Key words: virtual exhibition hall, customized, virtual simulation, reusability
