Set the Default Viewer

If you have an HTML5-enabled web browser, you can view virtual worlds with either the default Simulink^® 3D Animation™ Viewer or your web browser. You determine the viewer for displaying your scene using the vrsetpref and vrgetpref commands.

This procedure assumes that you are working with a PC platform.

1. When you install Simulink 3D Animation, the Simulink 3D Animation viewer is the default viewer. If you are not sure whether the default has been changed, you can determine your default viewer by typing:

   vrgetpref 

   The MATLAB^® Command Window displays

The DefaultViewer property is set to 'internal'. The Simulink 3D Animation Viewer is the default viewer for viewing virtual worlds. Any virtual worlds that you open are displayed in the viewer.

2. For example, at the MATLAB command prompt, open a model with default view set to DefaultViewer property is set to 'internal'.

   The Simulink 3D Animation Viewer opens.

   

3. To view the virtual world through the web browser, from the MATLAB command prompt, use the view and vrview commands.

4. Reset the Simulink 3D Animation Viewer as your default viewer by typing:

   vrsetpref('DefaultViewer','factory')

Alternatively, you can use the MATLAB File menu Preferences dialog box. See Set Simulink 3D Animation Preferences.)
