摘　　要：使用通用三维仿真平台SimGen构建双网结构的基于微机的塔台模拟机,重点探讨了多微机协同的实时三维视景渲染系统的体系结构,用UDP数据协议取得同步渲染数据,并提供了多机协同,用帧缓冲区以及网络流量控制的机制实现了抖动处理,使用两步线性航迹预测算法解决有可能出现的UDP数据的丢失。实践应用表明,基于SimGen运用多微机协同的视景实时渲染系统开发的塔台模拟机具有较低的成本和良好的性能,完全能够满足塔台管制训练和评估的要求。A universal 3D simulation platform SimGen was proposed. It was used to constuct a dual-net PC-based tower simulator. A high performance render system based on multiple PCs was investigated. One server PC and several client PCs were connected by high-speed LAN. UDP protocol was used to synchronize multiple client PCs to render 3D senery. Frame buffer and net flow control method was used to reduce render dithering. Two-step dead reckoning algorithm was used in case of frame loss caused by UDP protocol. These key features are proved to be reliable, and efficient when it is applied in tower simulator.
