基于X3D的工程制图网络虚拟模型库开发

Development of Web Virtual Model Library of Engineering Drawing Based on X3D

网络虚拟模型库在工程制图教学中有着广泛的应用前景。相对于VRML,X3D作为新一代虚拟现实网络程序语言具有更成熟的标准。论文重点介绍基于X3D开发网络虚拟模型库的过程及关键技术,并通过实例说明建立三维模型与实现过程虚拟的方法。网络虚拟模型库可弥补课堂教与学的不足,也可作为远程教育的教学工具。

Web virtual model library has a widespread use in the teaching of engineering drawing.Compared to VRML,X3D is a new generation of network programming language and has more mature standard.This paper introduces with emphasis the process and key technology of a web virtual model library developed by using X3D,and illustrates methods of building 3D model and making realization process virtual.Web virtual model library not only compensates the shortcoming of in-class teaching and study,but also is a good tool for distance learning.
