From the MATLAB software, you can set positions and properties of VRML objects,
create callbacks from graphical interfaces, and map data to virtual objects. You can also
view the world with a VRML viewer, determine its structure, and assign new values to
all available nodes and their fields.
The software includes functions for retrieving and changing the virtual world properties
and for saving the VRML files corresponding to the actual structure of a virtual world.
The MATLAB software provides communication for control and manipulation of virtual
reality objects using MATLAB objects.
For details about interacting between MATLAB and virtual reality worlds, see “MATLAB
Interaction”.
View Dynamic System Simulations
After you connect the virtual world to the dynamic system model, use a VRML viewer to
view the virtual world representation of the dynamic system simulation.
• In Simulink and SimMechanics, simulate the model that is connected to the virtual
reality world.
• In MATLAB, use the view function to view a vrworld object that the MATLAB code
updates with data values.
While running a simulation, you can change the positions and properties in a virtual
world.
For information about using VRML viewers to navigate a virtual reality world, see “View
Dynamic System Simulations”.
Share Dynamic System Simulation Visualizations
You can share dynamic system simulation results with others by:
• Capture animation frame snapshots or record animations for video viewing. See
“Capture Frames” and “Record and Play Animations ”.
• In addition to the single computer configuration (when MATLAB, Simulink, and
the virtual reality representations run on the same host computer), Simulink 3D
Animation software also allows a client-server configuration. In this configuration,
an Orbisnap VRML viewer on a remote client can connect to the server host on which
