随着虚拟现实技术的发展，并行绘制系统的日益成熟，为玩家提供大尺寸、高分辨率、广视角的沉浸式游戏画面成为国内外研究的热点。相比于场景较为简单的虚拟现实系统，并行绘制游戏系统场景复杂，同步对象多，同步数据量大，已有的虚拟现实技术并不能满足并行绘制游戏系统的需求。对并行绘制游戏系统进行研究与分析，将游戏世界中运动对象进行封装与解析，为实现游戏状态同步增加对象容错信息。为实现游戏同步数据高效可靠的传输，提高游戏并行绘制框架的可伸缩性和扩展性，系统基于Multicast协议设计了一套高效可靠的通信机制，与TCP协议、RUDP协议及RSP协议进行对比分析实验。实验结果表明，并行绘制游戏系统中基于Multicast的通信协议相比TCP协议、RUDP协议及RSP协议具有更好的性能及可伸缩性。

With the development of virtual reality and the growing maturity of parallel rendering system,it has become the research focus at home and abroad that how to offer players the immersive game screen in large size,high resolution and wide viewing.Compared with the virtual real-ity system with relatively simple scene,parallel rendering game system has complicated scene,multiple synchronisation objects and huge synchro-nous data,and the existing virtual reality technology cannot meet the needs of parallel rendering game system.We study and analyse existing paral-lel rendering game system,encapsulate and parse the moving objects in game world,and add fault-tolerant information of object for realising game state synchronisation.Meanwhile,in order to achieve efficient and reliable transmission of games’synchronous data,we improve the scalability and expansibility of game’s parallel rendering framework.The system is designed an efficient and reliable communication mechanism based on Multicast protocol,and is made comparative analysing experiments with TCP protocol,RUDP protocol and RSP protocol.The experimental results show that in parallel rendering game system,Multicast-based communication protocol has better performance and scalability than other three protocols.
