Agenda: review submission status and issues list for X3Dv4.  Determine whether to meet or extend the planned deadline for contributions of 16 DEC 2019 (next Monday).

Regrets: Don Brutzman, Anita Havele.  Working group cochairs Nicholas Polys and Vince Marchetti are moderating.

All inputs welcome!


The X3D Graphics Working Group addresses all X3D specification issues and coordinates the technical development of future improvements.

Members and invited experts are welcome.  We are an open organization. Please let us know if you have an important topic to present or discuss.

Each week we report out both public and member-only information - membership has value.  To become a Web3D Consortium member:

Teleconference information appears below.


1. *X3Dv4 Submissions Review*

Are there any other pending contributions?

Major pieces of work in progress and highly mature include:

a. glTF lighting and physically based rendering, Michalis Kamburelis

b. X3D Sound Component and HTML Audio, Athanasios Malamos and Efi Lakka

c. Projective Texture Mapping (PTM), Kwan Hee Yoo

d. Many specification improvements and additions.

Key references:

[2] X3Dv4 Highlights

[3] X3Dv4 Implementations Status

[4] Draft X3Dv4 specification from SIGGRAPH, August 2019

[5] Mantis Issue Tracker (requires 2 sets of member login)

You can quickly see all X3Dv4 issues (with tag V4.0) by selecting the filter "X3Dv4" within mantis.

Looks like we are ready to proceed to the next phase...  agreed?  Anything else?  *Group review and consensus please.*

As specified in the reference pages, our next steps of implement/evaluate over the next quarter include
- finished specification prose in github,
- addressing all mantis issues,
- proper example X3D models available for each node/field,
- validation tools confirming examples are satisfactory,
- two or more implementations (X3DOM and X_ITE, others),
- consensus by working group, approval by Web3D Consortium, submission to ISO.


2. *IPR statements*

Terms of membership and a requirement for contributing technology is to sign the Web3D Intellectual Property Rights (IPR) Policy asserting that no known patented technology subject to licensing is being submitted.


Web3D Executive Director Anita Havele is checking past records.  Since many of these were signed years ago, she may decide to ask everyone contributing to X3Dv4 specification to again assert that they are following the IPR policy.


3. *Web3DUX Working Group Proposal*

Thanks for all review of Web3DUX Working Group Proposal and draft Charter.  Dr. Feng Liu and Dr. Amela Sadagic are performing final review and anticipate submission to Web3D Board of Directors shortly.
