【摘要】 VRML提供了在WEB上进行虚拟装配的基础,而要实现定量而不仅仅是定性的装配,需要深入的工作。本文着重讨论了VRML动态行为的机理,以及利用Java对VRML对象进行控制的机制,具体阐述了script结点功能,Java和VRMLScript的比较。文中以虚拟装配仿真中的零件旋转控制为例,对定量精确旋转进行理论分析并说明了具体实现的方法,应用程序由C++和JAVA编制完成。更多还原

【Abstract】 VRML offers the base of virtual assembly through the web, it should realize assembly not only qualitatively but also rationally and need further research. This paper emphatically discusses the dynamic behavior mechanism of VRML, and the mechanism of controlling VRML objects with Java. It also illustrates the functions of script node in detail and the comparison between Java and VRML Script. The control of accessories rotation in the field of virtual assembly simulation is taken as a example to analyze the rationally rotation theoretically and illustrate the realization method in detail. The application is programmed in C++ and JAVA.更多还原
