Abstract: Retained-mode parallel graphics systems have great potential in parallel performance. A transparency, effective strategy for graphics objects distribution is the basic of retained-mode parallel graphics system. A systematic solution is presented. It includes the definition of graphics objects, transparency object creation, automatic coherence maintenance, state caching, delayed update and message-based image synchronization. The solution realizes automatic, high-performance graphics object distribution and is tested in MSPR which is high performance parallel rendering system based on cluster.

Key words: Parallel graphics system, Retained-mode, Object distribution, Delayed update

摘要： 保留模式并行图形系统在并行性能上有着巨大的潜力。透明、高效的图形对象分布是保留模式并行图形系统的基础。该文提出了一种完整的策略，包括通用的图形对象定义、透明的对象创建和自动一致性维护机制、状态缓存、延时更新、基于消息应答的图像同步输出。该策略实现了自动、高效的图形对象分布，并在高性能集群并行图形系统MSPR中得到了验证。
