分布式虚拟海战场仿真关键技术研究

在分布式虚拟环境下进行大规模军事战场仿真是目前仿真领域的研究热点。作为虚拟战场仿真的重要组成部分，分布式虚拟海战场仿真主要是解决大面积海浪视景实时生成和网络数据量太大引发的网络延迟这两个关键性问题。本文以海浪统计学模型为基础，采用视点相关的LOD模型实现了海面多细节层次建模，有效提高了大面积海浪视景仿真的实时性和逼真度；并基于Winsock 的TCP/IP协议，采用多播技术和推算定位技术，大大减少了分布式虚拟海战场仿真中的网络数据流量，实现了多通道视景同步，取得了较好的效果。

Research On Visual Simulation Of Distributed Virtual Naval Battlefields

The large-scale simulation of battlefield at the sea is the hot topic in the area of Distributed Virtual Environment at present. As a important part of it, simulation of distributed virtual naval battlefield has to account for real-time simulation of ocean wave in wide area and delaying of network in larger data. Based on statistical wave models, this paper proposes a view dependent LOD model to realize a multiple level of detail modeling of ocean wave, and improves the real time and fidelity. As a further work, based on the Winsock TCP/IP protocol and using technology of multicasting and Dead Reckoning(DR), it decreases the data of distributed virtual naval battlefield and realizes a multi-channel view mosaic in several PC. The test shows the effectiveness of the work.
