(To be removed) Update virtual world
vrdrawnow will be removed in a future release. For more information,
see Version History.
vrdrawnow removes from the queue pending changes to the virtual
world and makes these changes to the scene in the viewer.
Changes to the scene are normally queued and the views are updated when
The MATLAB® software is idle for some time (no Simulink® model is running and no script is being executed).
A Simulink step is finished.
