[x3d-public] X3D Standards Working Group list of standards under revision

Sun Jan 12 10:15:00 PST 2025

Michalis, I had trouble reaching your EnvironmentLight link, probably my email client obfuscation error (possibly fumbling the parentheses).  I did find this page, which is hopefully what you intended:

As I'm sure you recall, EnvironmentLight was definitely something we tried to accomplish earlier as part of X3D 4.0 finalization.  It was not quite finished then, but certainly remains of interest as we all continue working to maintain interoperable loading of glTF models in X3D4.  Prior high-water-mark status online at

  *
Mantis1336: 17.4.2 EnvironmentLight - Khronos glTF extension for image based lighting
  *
https://mantis.web3d.org/view.php?id=1336
  *
Many entries, then
  *
"TODO
     *
prepare draft specification prose for X3D 4.1
     *
share examples in X3D Examples Archives
     *
encourage adoption by authors and tool builders"

Looking forward to renewed progress... have fun with EnvironmentLight!  🙂

all the best, Don

NPS WARNING: *external sender* verify before acting.

Thank you enormously for everything you're doing to keep this
coordinated. Onward we go!

From my side, things I'd like to design as X3D extensions and propose
to be included in the next version of X3D standard, hopefully some time in 2025:

- An (optional of course) way to specify mesh data as binary blobs, in
a way compatible with glTF:

The pages above contain information about the details - why I think
it's useful+important, what I know, what I don't know and need to
learn (including experimenting with implementation) to make it happen.

Let's have a productive 2025 :)
