This is the new, X3D version of WebTOP. It currently has thirteen modules
and three more are under development. WebTOP 6.0 is a platform-independent,
Java application that the user downloads
(from here) and runs locally on his
computer. The only requirement for running WebTOP 6.0 is that the user’s computer
has a fairly recent version of Java installed on it: Windows (version 1.6 or better),
Mac (version 1.5 or better), Linux (1.6 or better). Instructions for checking
your version of Java can be downloaded from here. A current version of Java
available for download is located
When you click on the WebTOP 6.0 “from here” download link above, you be given
the choice to open or save the WebTOP 6.0 installer program (WebTop-installer.jar).
After doing one of these two things, you should run the installer program, during
which you will be given the option of having to place a shortcut on your desktop,
which most people will do. When you click on the shortcut, the WebTOP Modules
Menu pictured below should appear.
Figure 1 The WebTOP Modules Menu.
You may now start a module by clicking on the corresponding button on this interface. For example, if you click on the Michelson Interferometer button, you will get the WebTOP Window for this module, which is pictured below.
Figure 2 The WebTOP Window for the Michelson Interferometer module.
This window contains the interactive simulation. You may now change the parameters by interacting with the widgets in the scene, or by typing the desired parameter values into the number boxes in the gray console, which is located towards the bottom of the scene. You may also use the navigation icons, which are located just above the console, to rotate, zoom into, or pan the scene.

The menu at the top of the secondary window allows you to choose any of the other activities. When you click on a new activity, the activity you are in is replaced by the new activity.
