[x3d-public] X3D minutes: X3D Graphics Specification Relationships, request review of Integrating X3D and glTF

Fri Aug 5 10:30:23 PDT 2022

Attendees: Anita Havele, Dick Puk, Don Brutzman

We normally meet Fridays 09-1000 pacific.  (Regrets, no meeting next week.)

1.	ISO Annual Meeting.  Dick and Don reviewed almost-complete annual
meeting of ISO standards committee SC24.  Our liaison report has been shared
with Web3D Consortium members providing detail on all Web3D X3D and HAnim
issues.  Once the ISO meeting resolutions are shared and reviewed with
members, we'll be posting the Web3D Liaison report for public awareness.
Summary:  everything we have declared is progressing well.

2.	X3D Graphics Specification Relationships.  We have made some small
adjustments to our (very busy!) chart describing all Web3D Consortium
standards, and how they relate to other standards.  Updated online at

https://www.web3d.org/specifications/X3dGraphicsStandardsRelationships.pdf

Improvements to color legend:

*	Grey, Proposed
*	Orange, Working draft in progress
*	Yellow, ISO balloting in progress
*	White, ISO approved

Thus three standards are in ballot (X3D 4.0 Architecture, X3D 3.3 SAI
Bindings for C, C++, C#) and one standard is getting updated (X3D SAI from
3.3 to 4.0).

Of note is that rough-draft notes for (X3D SAI from 3.3 to 4.0) are posted
as follows.  Next step will be to put HTML versions with editorial markup in
Web3D Consortium's github version control.

As ever, comments welcome.

3.	X3D and glTF Comparison.  Anita is checking our most recent postings
that compared glTF and X3D, which led to full support of glTF capabilities
in X3D4.

*	Integrating X3D and glTF: How to Play Together Well on the WWW
*	Nicholas Polys, Ph.D., October, 2019

and

*	X3D and glTF Features Comparison, 3 NOV 2017

glTfX3dFeaturesComparison.pdf

Hoping to confirm that everything there is still correct. changes in X3D4
likely means that some of these entries need to be updated.

Review comments and improvements are welcome.

4.	Web3D Ecosystem and the Metaverse - SIGGRAPH 2022 BOF.  An excellent
presentation is now available:

*	Web3D Ecosystem and the Metaverse - SIGGRAPH 2022 BOF, Join the
Web3D Consortium for a discussion on how #X3D technology contributes to the
Metaverse. From Interactive Real-Time 3D, to Mixed Reality and Humanoid
Animation #HAnim for an open Metaverse.

TODO: post two more videos from SIGGRAPH 2022 BOFs. hopefully next week.

5.	Metaverse Standards Forum.  As a Standards Development Organization
(SDO) Web3D Consortium is a founding member of Metaverse Standards Forum.
This work continues to ramp up rapidly, now with 1200 members.

Companies Cooperate to Foster Interoperability Standards for an Open
Metaverse

Web3D Consortium actually has a lot of available technology capabilities in
this space.  To learn more, please see

*	"The Metaverse Standards Forum provides a unique opportunity to
achieve secure, collaborative (interoperable), durable, and pervasive
Mixed-Reality content," said Nicholas Polys Ph.D., president of the Web3D
Consortium.

6.	Or else.  Have fun with X3D!  8)

all the best, Don
