[0.2]	[x3d-public] X3D minutes, 5 FEB 2021: NWIP complete, WD3 finalization, CD submission to ISO


1. Draft X3D4 specification available

Am (overwhelmingly) happy to report that X3D4 Committee Draft (CD) is now stable and submitted to ISO.

All links of interest available at

[1.1]	X3D4 Version 4 Overview

[1.2]	X3Dv4 Public Working Draft

All prior comments are available and marked up in color-coded styles for Working Draft 3 (WD3).

[1.3]	X3D4 Working Draft 3 (WD3)

Web3D version of pristine Committee Draft (CD) submitted to ISO is available with no markup.

[1.4]	X3D4 Working Draft 3 (WD3)

Issues and resolutions are found in Mantis.  Multiple implementations and resources available.  Summary:

[1.5]	[x3d-public] X3D4 Architecture validation and implementation update, with thanks

Enjoy!  8)


2. Active working-group meetings

A lot is happening to adapt and use X3D4!  Watch the x3d-public list for minutes and announcements:

[2]	Web3D Working Groups

a. Web3DUX meets (typically every other) Monday 1015-1100 pacific

b. Semantic X3D discussion Tuesday, timing varies

c. Communications team (members only) Wednesdays 8-9 pacific

d. Audio implementation Wednesdays 1000 pacific

e. CAD Design Printing Scanning (members only) Thursday 8-9 pacific

f. X3D specification editors meet weekly, next topic is X3D SAI 19775-2 review.

As discussed in Monday's Web3DUX meeting, comments improvements and incremental extensions to X3D4 remain possible during ISO balloting this year.


3. Webinar planning

Great suggestion by Nicholas - discuss potential webinars in coming months.  Volunteers (and superstar requests) welcome.

a. Audio.  Efi Lakka is finalizing her full integration of Web Audio API in X3DOM, and is happy to lead a video webinar in March performing a code walkthrough.

b. DIS Stream recording. Don Brutzman can share this week's presentation to SISO on recording DIS to create X3D Position/Orientation interpolators, aka “A Stream is a Stream”.

[3]	Repeatable Unit Testing of Distributed Interactive Simulation (DIS) Protocol 
Behavior Streams using Web Standards

c. Vince (and maybe Andreas) can demonstrate use of online tools (such as Glitch) for construction of 3D web pages.

Let's think about how to present all past and upcoming webinars, on a webpage and Twitter too.  Hoping that by creating a schedule it will encourage lots of good sessions.


Have fun with X3D4!  8)

all the best, Don
