1.	X3D 2023 goals.  Our primary activities for X3D Working Group in
2023 are focused on broad and correct deployment.

a.	Encourage consistent rendering, interaction and usage for the many
tremendous capabilities in X3D4.
b.	Update ISO specifications and implementations for multiple
programming languages and file encodings to match X3D4.

2.	Web3D 2023 Conference

Call for papers now available.  What a powerful program!

*	Web3D 2023, 9-11 October 2023, Vicomtech

Towards interconnectivity of Metaverses

The purpose of the 28th International ACM Conference on 3D Web Technology
(Web3D 2023) is to study and share the principles and the latest
advancements in connected 3D universes. Provide navigation metaphors that
allow users to move seamlessly from one virtual world to another.

The goal of the conference and of the Web3D community, which has a rich
history of developing technologies that enable the creation, transmission,
access, interaction, sharing, and visualization of 3D universes. Bringing
together a diverse group of individuals to share innovative and influential
thoughts on how the metaverse can revolutionize the future of
communications. This includes topics such as 3D applications and services
accessible through a wide range of devices, from simple mobile phones to
more complex systems such as AR/VR headsets, and heavily populated virtual
worlds, especially those connected through high-speed, low-latency networks.

The 28th International ACM Conference on 3D Web Technology (Web3D 2023) is a
major event for the Metaverse community. Sponsored by ACM SIGGRAPH, in
cooperation with Web3D Consortium and supported by Eurographics, this
conference is hosted by Vicomtech and brings together experts from around
the world to discuss the latest research, development, and practices related
to the Metaverse.

It will be really interested if we can start collecting and disseminating 3D
models as part of the publication process.  Anyone interested?

3.	X3D 4.0 editors-draft IS.review preparation now in progress

Have begun applying changes from editors review of DIS spec, in preparation
for final IS submission to ISO.   Many changes are complete, several pending
ISO comments require lengthy double-checking.   Marked-up specification
draft visible at

*	https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-IS.
review

As before, each comment is being resolved in Mantis.  Mantis issues are not
closed until reviewed together.  Specification changes are checked into
GitHub.

*	Mantis issue resolution
*	https://www.web3d.org/member-only/mantis/view_all_bug_page.php

*	Review draft
*	https://github.com/Web3DConsortium/X3D/tree/master/ISO-IEC19775/ISO-
IEC19775-1/ISO-IEC19775-1v4.0/ISO-IEC19775-1v4-IS.review

*	Editors comments
*	https://github.com/Web3DConsortium/X3D/blob/master/ISO-IEC19775/ISO-
IEC19775-1/ISO-IEC19775-1v4.0/ISO-IEC19775-1v4-DIS.ISO/Disposition%20of%20Co
mments%20on%20ISO_IEC_DIS_19775-1_(Ed_4).pdf

When these changes are all complete and reviewed satisfactorily, I will
again fire up the build scripts to scrub all style markup appropriately, to
create a separate pristine version for ISO submission.

4.	X3D4 Sound Component review

*	Minutes 3 MAR 2023: X3D4 Sound Component and W3C Audio API review
*	https://web3d.org/pipermail/x3d-public_web3d.org/2023-March/018574.h

Dick Puk sent a message to Web3D member-only X3D list about only accepting
editorial/errata changes at this late date of X3D 4.0 finalization.  Thanks
for that.

*	[x3d] Recent discussions about changes to the X3D 4.0 Sound
Component

Things that appear possible:

*	clarifications needed in prose for 16.4.13 ListenerPointSource and
16.4.18 SpatialSound nodes.
*	https://www.web3d.org/member-only/mantis/view.php?id=1436
*	“If the dopplerEnabled field is TRUE, then sound sources which are
moving spatially in the transformation hierarchy, relative to the location
of the ListenerPointSource node, shall be modified by applying
velocity-induced frequency shifts corresponding to Doppler effect.”

*	Correcting mistaken type, also for specification consistency: SFTime
*	DynamicsCompressor : X3DSoundProcessingNode {

  SFFloat  [in,out] attack   0.003  [0,∞)

  SFTime   [in,out] release  0.25   [0,∞)

*	Convolver buffer[] array is quite difficult to use, allowing
AudioClip as an alternative seems like an obvious (previously overlooked)
remedy.

5.	Comment reconciliation

Dick Puk and I will review correct completion and resolve each of the
following applied comments.
