Abstract: In traditional distributed visual simulation, systems always use a single model, which results in uneven geometry resource allocation, not meeting the real-time requirements and other issues. To address those problems, the multi-resolution representation principles will be introduced into the design of the visual simulation systems. The research will be done on the load match under conditions of running different resolution models in computing nodes of the system. Considering the influence of the network bandwidth to transmission, at the same time, the research will also be done on the load match under the conditions of running those in displaying nodes of the system and a dynamic negotiation algorithm of the multi-resolution models is given, the application effect of using the multi-resolution methods is evaluated. The experiment proves that under the real-time requirement, the virtual visual system will run more efficiently by using multi-scale representation, under the uneven conditions of computing nodes, network transmission and displaying nodes.

Key words: distributed visual simulation, multi-resolution representation, load match, network transmission

摘要： 在传统分布式视景仿真中，系统均采用单一的模型，从而导致了系统中几何资源分配不均匀，无法满足实时性要求等问题。针对这一情况，将多分辨率表达的方法和原理应用于视景仿真系统中，对计算节点运行不同分辨率模型的负载匹配进行研究，考虑网络带宽对网络传输的影响，同时对显示节点运行多分辨率模型进行研究，给出了一种针对多分辨率模型的动态协商策略，对多分辨率表达的应用效果进行了验证。实验证明了运用多分辨率表达原理，能够应对系统在计算节点、网络传输以及显示节点上的不均衡情况，在保证系统实时性的前提下使系统运行更有效率。
