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

Sun Jan 12 00:15:25 PST 2025

Thanks for multiple efforts and thoughtful posts.

We certainly have more options for X3D extensibility than ever before, now that we've achieved the X3D 4.0 Architecture.  It is also much easier for Web3D Consortium to consider recommendations for incremental improvements to our specifications.

Some questions please:

Looks like functional descriptions  and technical references aren't listed?  There must be something you are each referring to...

Wondering what is the relationship to glTF?

Wondering what is relationship and potential value for Blender export to X3D?

As for BlendMode: Note that Castle Game Engine / Castle Model Viewer
also support it:

I agree BlendMode is worth adding to the spec, but *not* with all the
enums. The enums currently available match all OpenGL / OpenGLES /
WebGL capabilities, but it implies a lot of possibilities and I think
only a few are really practically useful for users. I would like to
research what is supported in this regard by Vulkan, Direct3D, and
choose a "common subset" for the spec.

Of course particular browsers could still extend allowed options to enable more.

Regards,
Michalis
