Internet上的3维动画设计
摘要：3D图形技术并不是1个新话题，在图形工作站以至于PC机上已日臻成熟，并早已应用到各个领域。然而互联网的出现，却使3D图形技术发生了微妙而深刻的变化。Web3D协会（前身是VRML协会）最先使用Web3D术语，这1术语的出现反映了这种变化的全貌。没有人能严格定义Web3D，在这里我们把Web3D理解为：互联网上的3D图形技术，互联网代表了未来的`新技术，很明显，3D图形和动画将在互联网上占有重要的地位。
Java3D API是Sun定义的用于实现3D显示的接口。使用Java的重要理由之1是它的平台无关性。Java3D提供了基于Java的上层接口，并把OpenGL和DirectX这些底层技术包装在Java接口中，这种全新的设计使3D技术变得不再繁琐并且可以加入到J2SE、J2EE的整套架构，保证了Java3D技术强大的扩展性。毕业设计以Java3D为开发平台，利用Java语言强大的网络功能，实现了在网页上对3D动画进行显示和操作。

Design of 3D Animation on Internet
Abstract：The 3D graph technology is not a new topic, in the graph workstation downtown PC machine already more or day matured, and has applied to each domain. However the Internet appearance caused the 3D graph technology to occur actually being subtle but the deep transformation. The Web3D association (predecessor is the VRML association) uses the Web3D terminology first, this terminology appearance had reflected this kind of change complete picture, nobody can strictly define Web3D, in here we do the Web3D understanding is On the Internet 3D graph technology, the Internet has represented the future new technology, is very obvious, the 3D graph and the animation will hold the important status on the Internet.
Java3D API is a connection that the Sun definition uses in realizing the 3D graph display. Uses one of Java important reasons is its platform relevant, has provided based on the Java upper formation connection, take OpenGL and DirectX the Seafirst floor technology packing in Java connection. This kind of brand-new design causes the 3D technology to change no longer tediously and may join to J2SE, the J2EE entire wrap over head construction; these characters is guaranteed the Java3D technology for extension. This article develops the platform take Java3D, uses the Java language formidable network function, realized has carried on the demonstration and the operation on the homepage to the 3D animation.
