The design and implementation of a real-time walkthrough system supporting cooperative manipulation

In DIS, simulated scenes with extreme complexity become much more common, which will definitely advance much higher requirement on both real-time interaction and cooperative manipulation among group members. We thus propose a kind of schedule based parallel processing model, in which the parallel processing of the whole rendering pipeline and cooperation among members are combined together effectively. The constitution of our model and its implementation are discussed in detail. This model has been successfully applied in the development of OADS, and its satisfactory results, including the fine image, real-time performance, good workload balance at the server, friendly cooperative interface and so on, illustrate its efficiency.
