Research on key features of PC-based tower simulator

A universal 3D simulation platform SimGen was proposed. It was used to construct 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.
