[x3d-public] ANARI+x3d = standard x3d raytracing?

[John Carlson]

If there is enough interest, I will create an X3D JSON to ANARI website,
but first, the conversion.

If people have specific JSON files from the archive converted, please
provide links.   They should have an Interchange profile and no extra
components.  Also, I believe that Text is unsupported by ANARI.
