摘 要：Virtual reality based visual interactive simulation system is proposed and completed,which applied integrated intelligent control to ship steering and main engine.For the multipoint communication of the proposed distributed visual simulation system,a DCOM based communication model is discussed.The group communications is divided into three layers from bottom to top.Based on static and dynamic combined algorithm,a dispatcher using centrality load balancing is also presented.
