needed.

  Here, your interaction with the browser through the octave command
line is minimal. You tell it 'Start!', 'Stop!', 'Display this, please'
and eventually ask it what objects the user clicked upon. For changing
the viewpoint and doing snapshots or films, you use the browser's
interface.

  I am not trying to match it. I don't know it but for a short
interaction a few years ago.
