Virtual Reality Toolbox

Creating a vrworld Object

To connect MATLAB to a virtual world, you need to create a vrworld object. A virtual world is defined by a VRML file with the extension .wrl. For a complete list of virtual world objects, see vrworld Object Reference, vrnode Object Reference, and vrfigure Object Reference.

After you create a virtual world, you can create a vrworld object. This procedure uses the virtual world vrmount.wrl as an example:

1. Open MATLAB. In the MATLAB Command Window, type

• myworld = vrworld('vrmount.wrl')
  

1. MATLAB displays

   • myworld = 
         vrworld object: 1-by-1
     

2. Type

• vrwhos
  

1. MATLAB displays the messages

   • (untitled)
             Closed, associated with 
             'C:<matlab root>\toolbox\vr\vrdemos\vrmount.wrl'.
             Visible for local viewers.
             No clients are logged on.
             World id is 'W995480635991'.
     

    The vrworld object myworld is associated with the virtual world vrmount.wrl. You can think of the variable myworld as a handle to the vrworld object stored in the MATLAB workspace.

Your next step is to open a virtual world using the vrworld object. See Opening a Virtual World.
