【摘要】 进入20世纪90年代以后，以Internet为代表的计算机网络得到了飞速的发展，因为Internet正在改变着我们工作和生活的各个方面，它已经给很多国家带来了巨大的好处，并加速了全球信息革命进程。而在机械制造行业中充分利用网络技术，进行图形系统处理，已成为目前的一个研究方向。本文首先对现在使用的Internet、WWW的结构和Web技术基础进行了简单介绍，并选择了B／S系统作为本系统的框架结构。然后，在B／S结构模型中，采用Java技术，使用客户端的Java Applet技术、服务器端的Java servlet技术，开发了客户端和服务器端小程序，实现了网络的三维通讯机制。最后，对Java3D建模语言进行了应用，开发一个基于网络的三维图形系统，实现了建模系统的点、线、面、体等的初步开发，为下一步进行更深入的研究积累了经验。本文从技术上证明了基于网络的三维图形系统的可行性，并利用以上技术设计实现了基于网络的三维图形的原型系统，实现了基于网络的简单三维实体的建模、交互式图形操作和服务器端演算等功能。随着制造业的迅速发展，它们都强调一种灵活的设计生产模式，以满足异地设计、制造以及国际协作生产的需要，而Internet作为一种高效、迅速、全面的通讯手段，将在CAD／CAM系统中发挥更加重要的作用，并使CAD／CAM系统资源得到充分的利用。更多还原

【Abstract】 Enter 20 centuries 90’s, Internet as the representative of network got to fly in development, because Internet was changing our work and life in each of the aspect, and Internet had already bring a lot of advantage to nations, and accelerated the world information progress. Take advantage of the network technique in the machine, handle the sketch system, Which become of a research direction now. Firstly, the text introduced the construction of the Internet and WWW and the technique of the Web and selected the B/S construction mode as the system frame. Then, the text developed a program to realize the three-dimensional communication system in the B/ S construction model by using Java Apple and Java servlet technique. At last, The text adapted Java3D modeling language to develop a web-based three-dimensional graphics system, which realized an initial develop modeling system and experienced to go deeper into research for next step was accumulated. The text proved the possibility of web-based three-dimensional graphics system from the technique, and realized the prototype system and the modeling graphics communication operation and the calculation function on server side. With the developing of manufacturing industry, they all emphasize a good production mode to meet the foreign land design, and meet the demand of the international manufacturing, Internet as an efficiently, quickly, completely communication ways, which will get to more important in the CAD/ CAM system, and make fully use of the CAD/ CAM system resources.更多还原
