Open a Virtual World with MATLAB
Opening a virtual world lets you view the virtual world in a VRML viewer, scan its
structure, and change virtual world properties from the MATLAB Command Window.
After you create a vrworld object, you can open the virtual world by using the vrworld
object associated with that virtual world. This procedure uses the vrworld object
myworld associated with the virtual world vrmount.wrl as an example:
1
In the MATLAB Command Window, type
open(myworld);
The MATLAB Command Window opens the virtual world vrmount.wrl.
2
Type
set(myworld, 'Description', 'My first virtual world');
The Description property is changed to My first virtual world. This is the
description that is displayed in all Simulink 3D Animation object listings, in the title
bar of the Simulink 3D Animation Viewer, and in the list of virtual worlds on the
Simulink 3D Animation HTML page.
3
Display the virtual world vrmount.wrl. Type
view(myworld)
The viewer that is set as the default viewer displays the virtual scene. This is
typically the Simulink 3D Animation Viewer unless you have a different viewer set.
Alternatively, you can display the virtual world in a VRML-enabled Web browser.
1
Repeat steps 1 and 2 of the preceding procedure.
2
Open a Web browser. In the Address box, type
http://localhost:8123
The browser displays the Simulink 3D Animation HTML page with a link to My
first virtual world. The number 8123 is the default Simulink 3D Animation port
number. If you set a different port number on your system, enter that number in
place of 8123 and restart MATLAB. For more information on the Simulink 3D
Animation HTML page, see “View Virtual World on Host Computer”.
