Virtual Reality Toolbox

Virtual Reality Toolbox Server

The Virtual Reality Toolbox uses an internal HTTP Server for communication between a Web browser and the MATLAB/Simulink environment. It generates the main Virtual Reality Toolbox HTML page with the list of currently available virtual worlds and sends VRML and other requested files and data to clients (VRML viewers).

The server is started when the Virtual Reality Toolbox is loaded into MATLAB. This happens whenever you use a Virtual Reality Toolbox block in a Simulink block diagram, or whenever you open a vrworld object in the MATLAB interface. The HTTP Server is shut down when you close all Simulink models that contain Virtual Reality Toolbox blocks, or use the vrclear command.

When the HTTP Server is running, your browser can see a list of available virtual worlds at the following address:

```
http://localhost:port_number
```

Remote users can connect to the following address:

```
http://your_machine:port_number
```

You can set the port number of the server in the Virtual Reality Toolbox Preferences dialog box from the Simulink interface, or use vrsetpref in the MATLAB Command Window.

Depending on the status of served vrworld objects, the list of available virtual worlds can be empty.
