Internet上的3維動畫設計
摘要：3D圖形技術并不是1個新話題，在圖形工作站以至于PC機上已日臻成熟，并早已應用到各個領域。然而互聯網的出現，卻使3D圖形技術發生了微妙而深刻的變化。Web3D協會（前身是VRML協會）最先使用Web3D術語，這1術語的出現反映了這種變化的全貌。沒有人能嚴格定義Web3D，在這里我們把Web3D理解為：互聯網上的3D圖形技術，互聯網代表了未來的新技術，很明顯，3D圖形和動畫將在互聯網上占有重要的地位。
Java3D API是Sun定義的用于實現3D顯示的接口。使用Java的重要理由之1是它的平臺無關性。Java3D提供了基于Java的上層接口，并把OpenGL和DirectX這些底層技術包裝在Java接口中，這種全新的設計使3D技術變得不再繁瑣并且可以加入到J2SE、J2EE的整套架構，保證了Java3D技術強大的擴展性。畢業設計以Java3D為開發平臺，利用Java語言強大的網絡功能，實現了在網頁上對3D動畫進行顯示和操作。
關鍵詞：Java3D；Internet；Web3D。
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.
Keywords: Java3D；Internet；Web3D.
