摘　　要：在SGI工作站上用Vega、Creator开发了攻防对抗三维显示节点,利用仿真的HLA标准开发了三维显示节点客户端联邦成员;提出了联邦仿真数据交互外层网络和三维数据交互的内层网络两层结构;利用TCP/IP可靠传输进行内层数据交互;在保证数据传输的精度和正确的前提下,有效的减小网络的通信量;对离散的三维数据进行平滑处理;使用特效渲染场景;采用多线程、多场景、多通道技术再现战场;给出了智能眼点选择的策略,解决了数据存储面临的诸多问题。The establishment of 3-Dimension Node about Attack and Defense was discussed in order to develop 3D-program based on the standard protocols High-Level Architecture （HLA）. Two level infrastructures of network including the external network based on HLA and the internal network based TCP/IP for the interaction of 3D-data were argued. On the premise of data＇s precision, the communication flux of network was reduced and the real-time 3D-data was smoothly processed. In addition, many special effects rendered were located in the scenes and intelligent eyes were designed to act as the observer for the scenes. The system has achieved a very good demonstration effect through the technique of multi-thread, multi-scene, multi-channel, multi-viewpoint.
