To connect MATLAB® to a virtual world and to interact with
that virtual world through the MATLAB command-line interface,
create vrworld and vrnode objects.
A virtual world 3D file defines a virtual world.
Note
The Simulink® interface and the MATLAB interface share
virtual world objects. This sharing of objects enables you to use
the MATLAB interface to change the properties of vrworld objects
originally created by Simulink with Simulink
3D Animation™ blocks.
After you create a virtual world, you can create a vrworld object.
This procedure uses the virtual world vrmount.wrl as
an example.
Open MATLAB. In the MATLAB Command Window, type
myworld = vrworld('vrmount.wrl')
The MATLAB Command Window displays output like
myworld = vrworld object: 1-by-1 VR Car in the Mountains (matlabroot/toolbox/sl3d/vrdemos/vrmount.wrl)
Type
vrwhos
The MATLAB Command Window displays the messages
Closed, associated with 'C:matlabroot\toolbox\sl3d\sl3ddemos\vrmount.wrl'. Visible for local viewers. No clients are logged on.
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.
