Unjarring the Java 3D Utilities

You might want to copy the j3dutils.jar file into a new directory and run the jar extraction utility on it. This will unjar an enormous number of classes that are provided in the form of the utilities package. This is a great way for the developer to understand some ways to create classes and utilize packages in future development projects. One of the frequently used classes in the Java 3D.utils package is the SimpleUniverse class, which contains utilities for creating a ViewPlatform and moving it back for viewing. For reasons that will be explained later, we tend to avoid using the SimpleUniverse class.
