【摘要】 针对海战场环境特点和需要,分布式虚拟海战场仿真主要解决大规模动态海面实时生成、计算机兵力生成和大规模网络数据同步三个关键技术问题。基于海浪统计学模型,采用快速傅立叶逆变换、层次细节技术和与视点相关的可见性预判断技术,实时生成动态海面,依据蒲氏风级与浪高的对应关系,模拟不同等级海浪;基于舰艇、飞机和导弹等实体作战和运动模型,采用简化技术,完成了计算机兵力生成和作战过程模拟;并基于winsock的TCP/IP协议,采用多播技术和推算定位技术,较好地解决了网络数据同步和多通道视景同步问题。通过建立的各种典型虚拟海战场环境.取得了较好的仿真效果。更多还原

【Abstract】 According to the characteristic and necessary of sea battlefield, the simulation of distributed virtual sea battlefields has three key questions on research. One is real - time rendering of dynamic ocean surface in wide area. Second is computer military create. The last is synchronization of network with larger data. Based on statistical wave models, this paper firstly realized a real - time rendering algorithm of ocean surface by used technologies of inverse Fast Fourier Transformation (FFT), lever of detail (LOD) and view - dependence visibility estimation and also classified ocean wave according to the correlation of wind and wave height. Secondly, computer military create and simulation of combat process was accomplished based on simpler combat and movement models. Lastly, based on the Win-sock TCP/IP protocol and using technology of multicasting and Dead Reckoning (DR), it resolved the question of net data synchronization and realized a multi - channel view mosaic in several PC. In a word, it achieves a better simulation effect through built diverse typical virtual sea battlefields.更多还原
