Research of conceptual modeling of virtual environments
(College of Information Engineering, Zhengzhou University, Zhengzhou 450001, China)
Abstract: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. ......
