基于三维漫游系统的优化策略

Urban underground pipe network becomes one of the most important infrastructures of modern life. 3D navigation system can show the spatial relationship and geography position clearly and vividly, which can support planning and management of the municipal construction. However, 3D navigation system needs acquire a huge of geography information from database so frequently that its performance has been greatly constrained. In this paper, we have analyze the Urban Pipe Network Management System and the features of 3D navigation system and then this paper has given a series of optimization methods, which mainly focus on database access and data buffer strategies, to improve the system performance.
