Cross-Platform Support

Virtual Reality Toolbox software Version 3.0 is supported on both PC and UNIX platforms.

Virtual Reality Toolbox Viewer

Virtual Reality Toolbox software Version 3.0 now contains a VRML viewer. You can use this viewer on all supported operating systems. With the Virtual Reality Toolbox viewer, you can move between predefined viewpoints in a virtual scene. You can also control the navigation method, speed, and rendering of the virtual world. From the MATLAB interface, you can control the Virtual Reality Toolbox viewer better than other VRML-enabled Web browsers.

Improved Performance

The communication between Virtual Reality Toolbox and VRML-enabled Web browsers is improved. You are now able to perform such tasks as controlling multiple objects in a virtual scene or setting multiple field values faster than before.

Improved MATLAB Interface

It is now easier to access and manipulate virtual world objects from the MATLAB command line. You can use dot notation to change object properties. Also, multiple field values are transferred between MATLAB and the Virtual Reality Toolbox server in a form consistent with their VRML representation.

Customized V-Realm Object Libraries

Compatibility Considerations

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

  1. Save the contents of the <MATLAB root>\toolbox\vr\vrealm folder to another location on your system.

  2. Uninstall the older version of the MATLAB product.

  3. Install MATLAB software Version 6.5 (Release 13).

  4. Install V-Realm using the command

    vrinstall -install editor
    
  5. Save the files from your old vrealm folder into the new vrealm folder.

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

After you have moved your files into the new vrealm folder 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.
