[x3d-public] got Three.js and X3D?

[Nicholas Polys]

It depends , doesn't it?

Interchange profile is straightforward and we all see certain geometry as
'the same' across formats...
so yes I agree glTF is appropriate for certain assets.
Especially now with X3D4 supporting glTF PBR constructs...
    but also the realtime essentials natively as in
          URL/URIs, lights, cameras, sensors, animation, LOD  constructs,
etc ...?

My awesome metaverse vehicle has doors, wheels, buttons, dashboards,
lights, switches, etc.
 that I expect to work the same with me across meta and real verses on the
Web.

I fully encourage hackers and vendors to add value for their users and use
cases.
Profiles and components are essential to this discussion; there are always
tradeoffs!
Shine On!

with best regards,
 _n_polys
