Explanation:

The CONE_SCRIPT node contains all the important information to connect the VRML to the Java file.

• The url field is the file location of the Java class which drives the animation. The class must be a child of the Script class in CP's Java library.
• The field is the name of a node which can be passed to Java and can be manipulated using the various functions form the library. In this example we won't make use of it.
• The clicked eventIn field is like a function declaration which allows us to route events from the VRML to a function in the Java program.
• The theRot field is of type SFRotation which means its value if a vector of 4 floats. The first three are the axis of rotation and the fourth is the angle in radians. The value for this will be set through Java and connected to the rotation value of the Cone.
