虚拟现实系统综合式框架模型的建模与系统设计

虚拟现实系统的模型结构和建模方法是虚拟现实研究领域中的一个重要内容,在对现有虚拟现实系统设计领域的成果进行分析和比较的基础上,建立了包含多构件的综合式框架模型结构,并提出了采用该模型结构进行虚拟现实系统设计的建模方法.综合式框架模型的建模方法采用分层设计方式,在每个设计阶段进一步详细划分了实现模型的步骤及所用到的技术.文中结合汽车动力总成虚拟装配系统实例介绍了采用综合式框架模型及建模方法指导并实现虚拟现实系统设计.

Research of the Virtual Reality System Model and the Modeling Approach

The model structure and the modeling approach of virtual reality (VR) system is the most important research content in VR research area. Based on analyzing and comparing work of the existing research achievements in VR research area, a comprehensive frame model (CFM) composed of multi components is established and the modeling approach of using this model in designing of VR system is proposed in this paper, and the meaning and the significance of these components are discussed. The hierarchical designing method is adopted in the modeling of CFM, the procedures and technologies in the modeling process of each design stage are proposed further. An automotive power plant virtual assembly system is used to illustrate the CFM and the modeling approach for directing and accomplishing the VR system design.
