Virtual Reality Toolbox Release Notes

Upgrading from an Earlier Release

This section describes an upgrade issue involved in moving from the Virtual Reality Toolbox 2.0 to Version 3.0.

Customized V-Realm Object Libraries

If you are on a PC platform and you created your own object libraries in V-Realm while using the Virtual Reality Toolbox 2.0, deleting MATLAB deletes these custom libraries. You need to save these libraries before uninstalling the older version of MATLAB:

Save the contents of the <MATLAB root>\toolbox\vr\vrealm directory to another location on your system.
Uninstall the older version of MATLAB.
Install MATLAB 6.5 (Release 13).
Install V-Realm using the command

```
vrinstall -install editor
```

Save the files from your old vrealm directory into the new vrealm directory.

MATLAB 6.5 should have the same directory structure as your previous version of MATLAB. If the directory structure is not identical, search your system for vrbuild2.ini. Edit the relative paths within this file to reflect the directory structure of MATLAB 6.5.

After you have moved your files into the new vrealm directory and customized your vrbuild2.ini file, do not reinstall the V-Realm editor. The command

```
vrinstall -install editor
```

replaces the existing vrbuild2.ini file with the default template file.
