Java 3D是Java语言在三维图形领域的扩展，是一组应用编程接口（API）。利用Java 3D提供的API，可以编写出基于网页的三维动画、各种计算机辅助教学软件和三维游戏等等。利用Java 3D编写的程序，只需要编程人员调用这些API进行编程，而客户端只需要使用标准的Java虚拟机就可以浏览，因此具有不需要安装插件的优点。

-Java 3D is a Java language extension of the field in three-dimensional graphics, is a set of application programming interface (API). Provided by Java 3D API, you can write a Web-based three-dimensional animation, a variety of educational software and computer-aided three-dimensional games. Programs written using Java 3D, just call the API programmer to program, and the client only need to use the standard Java virtual machine to browse, so has the need to install plug-in advantages.
