A VISUALIZATION SYSTEM OF 3D SIGHTS BASED ON WEB

Because the 3D sights is very complex, it is difficult to realize the simulation and visualization of 3D sights on internet. We design and develop a system of B/S architecture for interactively browsing the 3D sights on the Web. To support the simulation of 3D sights with high performance, an extended-relational logical model of 3D sights is designed, based on this model, the sights data can be organized and managed effectively by Oracle spatial. In addition, a specification for transporting sights data between Web server and browser is defined with XML, Additionally, an effective strategy for sights data schedule is designed to support the real-time rendering of 3D sights. With our system, user can interactively browse complex 3D sights on the node of internet.
