The 3D graph technology is not a new topic, in the graph workstation down to on PC machine already more or day matured, and has applied to each domain. However the Inter appearance, caused the 3D graph technology to occur actually and is occurring is 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 plete picture, nobody can strictly define Web3D, in here we do the Web3D understanding is: On the Inter 3D graph technology, the Inter has represented the future new technology, is very obvious, the 3D graph and the animation will hold the important status on the Inter. Java3D API is the Sun definition uses in realizing the 3D demonstration connection. Uses one of Java important reasons is its platform irrelevant. Java3D has provided based on the Java upper formation connection. Java3D OpenGL and DirectX these first floor technology packing in Java connection. This kind of brandnew design causes the 3D technology to change no longer tediously and may join to J2SE, the J2EE entire wrap overhead construction, these characteristics have guaranteed the Java3D technology formidable extension. This article develops the platform take Java3D, uses the Java language formidable work function nf, realized has carried on the demonstration and the operation on the homepage to the 3D animation.
