In order to run the simulation in Netscape, you should:

•	Use Netscape 4.5 or higher. You can download the browser in http://www.netscape.com/download/index.html .
•	Install Java Plugin. You can get the plugin from http://java.sun.com/products/plugin/index.html.
•	Install Java 3D JRE. You can get Java3D from http://java.sun.com/products/java-media/3D/index.html. (Note that there is an error in JRE or Netscape browser. You need to copy JAR files from lib/ext to lib in order to make the browser sees the files).
•	Use Java Plug-in Control Panel to set Java Run Time Environment to the one with Java 3D JRE.
•	If the color looks fuzzy in the 3D graphics, set the display to 65536 colors.

Then Try Simulation

If you want to run it in stand-alone or batch mode, read the document first, then download the software.

In any case, you may want to see an example first, and get to know the GUI of the simulation.
