多尺度表达在虚拟视景仿真系统中的应用研究

Research of Application of Muti-Scale Representation in Virtual Visual Simulation System

现在分布式虚拟实验技术与视景仿真技术深入结合,使虚拟试验系统得到了广泛的应用;传统的虚拟视景仿真,在系统的各个节点上均采用单一的模型进行运算;一方面,在小规模视景仿真中,使系统资源不能得到充分利用;另一方面,在大规模视景仿真中,又无法满足系统实时性要求;为了解决这种情况,将多尺度表达的方法和原理应用于视景仿真系统中计算节点和显示节点的设计,并对两类节点运行不同尺度模型的负载匹配进行研究,对多尺度原理的应用效果进行了验证;试验结果表明,采用粗尺度模型进行大规模视景仿真时,在保证实时性的前提下,能很好地满足真实性要求;试验证明视景仿真系统中应用多尺度表达原理将使系统运行更有效率,将为大规模虚拟视景仿真系统的设计提供了一种可行的思路。

Today, deep combination of distributed virtual experiment technology and visual simulation technology makes virtual test sys tern been widely used in various kind of fields. In traditional virtual visual simulation, a single model is running in each node of the system. On the one hand, in small--scale visual simulation, the system resources can not be fully utilized. On the other hand, in large--scale visual simulation, the system can not meet real--time requirements. To address this situation, the muti--scale representation principles will be in- troduced into the design of compute nodes and display nodes of the system. Research will be done on the load match under conditions of two kinds of nodes running different scales of model. This article evaluates the application effect of using the muti-- scale representation methods. The experiment improves that the virtual visual system will run more effective by using muti--scale representation. This research will provide a new feasible idea for the design of visual simulation system.
