摘　　要：为改善现今大规模场景并行绘制中的由于网络潜在的不稳定性所导致的各个绘制节点所出现的帧数据丢失以及帧绘制延缓等状况,提出了一种新的处理多屏显示的并行绘制同步控制方法。该方法利用一种新的基于缓冲机制和插值的思想,在少量牺牲几个绘制节点的绘制同步的前提下,使得整个绘制系统的绘制效率不受制于最慢绘制节点,并可以容忍各种网络延迟、仿真数据包丢失等网络不稳定情况。实验结果表明,该方法在一定程度上缩短了整个并行绘制系统平均每帧的绘制时间,画面显示的平滑性也有所改善,画面停滞现象相对减少。To develop the state of the loss of frame＇ s data or the delay of frame rendering in some rendering nodes as a result of the instability of the network in the current parallel rendering for large-scale scene, a new multi-display of synchronous control method is put forward. This method using a new method based caching mechanism and interpolation, with the premise of a small expense of several nodes＇ synchronous control, making the efficiency of the rendering system to draw not deciding by the slowest rendering nodes, and it can tolerate a variety of network latency, packet loss and other network simulation instability. Experiments show that this method reduces the rendering time of every frame in the system of parallel rendering, and improves the smoothness, and stagnation phenomenon of scene displav is relatively reduced.
