基于VRML场景的虚拟装配环境设计

Virtual Assembly World Design that Based on VRML Scene

Java 和VRML 的结合,构成了创建基于网络的大规模虚拟环境的理想综合平台,特别适合分布式VRML 场景的虚拟装配环境设计。给出了一种基于VRML 和Java的虚拟现实构建方法,即通过I-DEAS 完成虚拟产品的物理建模和装配设计,修改由I-DEAS的输出的VRML 文件,增加交互性所必需的传感器节点,然后利用VRML 的Script 和EAI将它们有机地集成在一起,在此技术上完成VRML 场景的动态生成、装配控制及装配过程的动画回放等功能。

The combination of Java and VRML constitutes the perfect integrated platform to create large scale of virtual world that based on network, especially suit for virtual assembly world design of distributed VRML scene. An approach to building virtual environments is proposed on the basis of VRML and Java in this paper. That is, I-DEAS is adopted to realize the physical modeling and assembly designing of the virtual product; edit the VRML files exported by I-DEAS, insert the necessary sensor notes to heighten interactive capability, the Script and EAI of VRML is utilized to integrate them organically. Based on this technology, the dynamic creation of VRML scene, the assembly control and animation of assembly sequence are realized.
