摘　　要：基于分布式的塔台模拟机中,难点是多机渲染的同步问题。文中提出一种使用双网结构的塔台模拟机体系结构,并从渲染空间同步、动态数据同步、帧同步和输入控制同步四个层次对多机渲染同步的问题进行分析,同时给出了相应的解决方案。在解决帧同步问题时,提出一种结合网络流量控制以及运动目标线性预测算法的改进桶同步算法,解决了多机渲染同步和三维运动目标平滑跨越多机多屏等技术难题。The synchronization of multi-machine rendering is the difficulty in distributed tower simulator. A kind of tower simulator architecture which using double-network structure is put forward, and the problem of multi-machine rendering synchronization is analyzed from four levels of rendering space synchronization, dynamic data synchronization, frame synchronization and input control synchronization. The corresponding solutions are given as well. During the solution of frame synchronization, a improved-barrels synchronization algorithm is brought out combined with network traffic control and linear forecasting algorithm for 3D moving targets. This algorithm resolves the technical difficulties such as the multi-machine rendering synchronization and 3D moving targets across the multi-machine and multi-screen smoothly.
