Note: de facto standard du jour.<br>
<br>
Stereo panoramas often stored left over right in same frame for a
square frame (Gear's max is 2160x2160 at the moment)<br>
<br>
Other options may involve cube maps, pyramid maps, cylindrical or
other types of mapping. I think a high-level node which may allow
for implementation of different layouts/formats would be nice.<br>
<br>
And, there should be an open ISO standards committee formed around
the format/layout/compression et al of 'vr video' (if there isn't
already one)<br>

There is monoscopic 360 Video - the phone/tablet/display has
only a single frame per frame. You can look anywhere, but there
is no 3D effect. Stereoscopic 360 Video has two frames per frame
- one for each eye. This usually requires a head display
(Cardboard, GearVR, etc.) and is frequently used with stereo
headphones. The movie was either filmed in 3D or 3D was made in
post production (current practice is to do it in post). <br>
<br>
There have been several productions of shorts that are of the
same quality as movies. <br>

<pre wrap="">In one native browser you can put side='left' ie
<Transform side='left'>
.. shows in the left side only..
</Transform>
<Transform side='right'>
..shows in the right side only..
</Transform>
Q. how does the video look?
If its side-by-side in the same frame, then you'd have different texture coords for left and right side.

Subject: [x3d-public] 360 Video
VR Video aka 360 Video is video that occupies all 4pi steradians of
view about the user. These videos come in stereo (3D) or mono. The
stereo movies need to be played through a device that generates a left
and right image and is typically viewed through Cardboard, GearVR, or
equivalent. This video is available on YouTube and several other
sources.
X3D provides a MovieTexture node that will display a video as a
texture. To make X3D more interesting (and usable) for VR
applications, support for this format is needed. The video is
frequently played on the inside of a sphere and the device's motion
sensors are used to provide orientation to the display.
Should X3D V4 have this capability?
Should a video-sphere be automatically provided?
Should a developer be able to choose a different screen-surface
geometry?
