JDK(Java Development Kit) & packages related Java 3D are preconditions to compile and run a java 3D programme.But java 3D is an option package to standard JDK, as well as java 3D package is not installed defaultly with JDK. So we should install in by ourselves.
You can download the binary package from:
You can choose your suitable version according to your platform, linux or windows as an example.
After installing it. some jars and *.dll will be found under %JAVA_HOME%/jre/lib/ext and %JAVA_HOME%jre/bin/, such as j3dcore.jar, j3dutils.jar, j3dcore-*.dll.
Then you can compile and run your java 3D program. Make sure your JRE(Java Runtime Enviroment) works smoothly.
Just a little summery. Suggestions are welcome. :)
