【摘要】 通过对不同CAD软件输出的VRML文件进行分析,提出了利用树形结构组织场景,将不同CAD软件输出的VRML文件进行标准化的基本方法。利用JAVA语言强大的编程功能和VRML2.0提供的EAI(ExternalAuthoringInterface,外部程序扩展接口)针对标准文件编写交互操作的程序,从而实现了对不同CAD软件建模的VRML装配场景的拆装、任意部分的隐藏和透明度调节等交互操作控制。更多还原

【Abstract】 This paper analyzes VRML files exported from different CAD software, and puts forward a method to organize the scene by using tree structure and to standardize these VRML files. Aiming at the standardized VRML files, this paper also designs a interactive program, which makes use of Java language and EAI provided by VRML2.0. The program achieves interactively operate such as assembly, disassembly, hiding and adjust transparence with different kinds of VRML assembly scene which produced by different CAD softwares.更多还原
