摘要
由于目前常用的概念建模方法对于虚拟环境中物体方位、行为和交互模型等信息缺乏足够的描述方法,在吸取现有概念模型建模概念和技术的基础上,提出了虚拟环境概念模型建模框架,给出了虚拟场景静态结构和动态行为的概念建模方法,并通过虚拟化学实验平台的设计和实现验证了方法的可行性。通过在虚拟环境设计阶段引入概念建模阶段,使不具备专业编程知识的普通人员通过使用图形化的建模语言也能够进行虚拟环境的开发,为虚拟环境的顶层设计提供了一个科学、有效的手段。
Existing conceptual modeling techniques are too limited for modeling a VR application in an appropriate way. Based on absorbing the concept and technology of existing methods, introduced the framework and methods of virtual environments conceptual modeling. The design and realization of virtual chemistry experiment platform indicated that the proposed conceptual modeling was effective. By introducing a conceptual modeling phase into the development process of VR applications, the intention of this research was that people having no background in VR would find easier to specify and build virtual reality application using graphical modeling language themselves and offered a scientific and effective method in virtual environment system simulation in top level.
