Temporarily cease Oculus DK2 rendering or hide display

[willpower2727]

None of the options stop rendering or hide it or whatever on the hmd.

viz.MainWindow.visible(False)

Works at hiding the mirrored window on my PC's monitor but the scene is still being rendered on the HMD. Interestingly

 hmd.remove()

Doesn't seem to do anything.

I will have difficulty in hiding the scene with a quad since the user is immersed in the scene (subject can walk around and interact with the scene). In order to hide the scene with a quad I'd have to have reliable information about the head position and orientation which in the scenarios where I want to hide things, this data is inaccurate.

Alternatively I think I'll try positioning a black sphere around the head when I want to hide the scene, so that only the position data needs to be robust.
