VRML Scripting:

Supported scripting languanges: Java, JavaScript, VRMLScript

ECMAScript is a version of JavaScript.

Each Script has a Field member eventIn and eventOut

Scripts are started with initialize just like java and ended w/shutdown

The event in function must be defined for each eventIn

The Advantage of Java is access to the network, more complex math, etc... Java will need to import from vrml package and extend the Script classIn Java eventIn is replaced by a processEvent() method called when an event arrives

Use fields to grab the field and eventOut pointers

Data Structures, classes, and socket stuff is provided in Java not JavaScript

Use scripting langs for simple stuff

Accessing the Browser itself from the script:

Add and delete routes

replace world, etc...

Access through the browser object

Modify the VRML spec by adding new nodes... i.e. subclassing or new classing

What about Java3D (Nadeau)

if you want algorithm-cs based graphics Java3D, OpenGL, etc...

if you want content develpment VRML

Java3D can load VRML files... and use Java3D for better control
