[x3d-public] x3d minutes 20 May 2022: submission of X3D4 Draft International Standard DIS) document nearing completion

Sat May 21 22:15:36 PDT 2022

Thanks Michalis, we were looking for you to confirm this one last time.
Commented out within Schema DTD Tooltips and X3DUOM, EnvironmentLight will
be deferred to X3D4.1

all the best, Don

Environment lighting (just like any kind of lighting, actually) is not part
of any glTF spec. I believe I mentioned it numerous times :)

And, in X3D, we're not ready to put this in spec (which is also my fault --
too little time). My progress is on

. The EnvironmentLight node I propose there is not yet finalized, no browser
(including my own CGE/view3dscene) has actually implemented it fully so far,
I would absolutely veto from including this in spec (even *if* glTF included
it in spec, but it doesn't). It will come, but we need to work on it more :)
