[x3d-public] New Image and Video Sphere X3D examples +

[Don Brutzman]

Wow, looks great!  Your team's sustained effort on these capabilities is
most impressive.

Questions on VideoSphere please:

   - Inspecting the source .x3d files, it looks like the VideoSphere
   pattern applies prepared MovieTexture and IndexedFaceSet nodes without
   creation of any new X3D node.
   - Were there any non-trivial additions to X3DOM source?  i.e. will other
   browsers need further work to support?
   - Do you expect there might be potential benefit to someday defining a
   new X3D node in order to encourage adoption?  The X3D specification doesn't
   distinguish between 360-degree video and other video formats.
      - Potential use case:  VideoSphere bubbles within a larger scene that
      permit close-up inspection from certain vantage points.  Such
bubbles might
      use TwoSidedMaterial to be semitransparent (or other Switch techniques to
      be hidden) within the larger scene.
      - interesting related capabiltity:  MatterPort, "Scanned-on-Demand 3D
      Models | Quick-Turn 3D Virtual Tours"
      - https://go.matterport.com/Capture-Service.html
   - Is the blue car going the wrong direction on a one-way street?
   autonomous driver, presumably...   🥴

Suggestions regarding MetaverseBookmark: to encourage further
experimentation and adoption, it would be good to

   - build an example template in X3D using MetadataSet
   - build a corresponding prototype for the same data structures,
   potentially adding self-validation (via Script) and external validation (by
   various tools),
   - add these to X3D Examples Archive

Standing ovation, again thanks for sharing these significant updates.

all the best, Don
