1. Regular meeting planned for Friday 9 MAY 2019 (08-0930 pacific) to focus on:
- Web3D and SIGGRAPH 2019 preparations
- Physically Based Materials and Lighting
TODO review: All information in minutes is suitable for public release. Member-only information is posted separately.
----
Members and invited experts are welcome. We are an open organization.
We meet regularly on Fridays 0800-0930 pacific. To join the teleconference:

Information inputs are always welcome. With much X3D activity occurring there is typically plenty to review each week, ensuring that our progress continues to be clearly recorded and communicated.
==================================
2. *Prior meeting minutes, recent highlights*
At this point we discuss recent meetings and current developments.
[x3d-public] X3D minutes 3 MAY 2019: C/C++/C# and Python progress, PointProperties validation for X3Dv4
http://web3d.org/pipermail/x3d-public_web3d.org/2019-May/010662.html
Note that definition of XML Schema/DTD/Schematron/Tooltips led to some refinements of PointProperties spec prose. Hoping someone can check the Mantis bug and GitHub document, as noted there.
Also of broad interest:
Web3D 2019 - REGISTRATION NOW OPEN
http://web3d.org/pipermail/x3d-public_web3d.org/2019-May/010660.html
[x3d-public] X3D Python availability, planning for releases at Web3D 2019
http://web3d.org/pipermail/x3d-public_web3d.org/2019-May/010690.html
"Incredibly It Is All X3D."
a. Do we need to have a volunteer to represent Web3D and X3D in the WebXR group? Seems like a valuable role for someone, especially if interested in X3Dv4.1 efforts. Having a 5-minute weekly update on WebXR activities might be useful. Web3D liaison to W3C for WebXR would be a formal position.
Agenda review: what else?
==================================
3. *Finalize Web3D 2019 submissions*
Brief discussion to resolve final questions.
a. X3D Semantic Web Workshop
b. X3Dv4 Implementations Tutorial
==================================
4. *Include PBR Physically Based Rendering in X3Dv4 Architecture specification*
Michalis Kamburelis will update us on his extensive work in this area:
https://github.com/michaliskambi/x3d-tests/wiki/Include-PBR-%28PhysicalMaterial-and-related-concepts%29-in-the-official-X3D-specification
- What is PBR and why do we want it in X3D?
- How to add PBR to X3D?
- Specification changes, to include PBR and related features
Goal outcome for today: define list of sections for X3Dv4 Architecture specification draft.
==================================
5. *Recent and Upcoming Events*
*Web3D 2019 Conference registration is open* hooray! Discount provided for ACM members.
https://web3d2019.web3d.org/registration
Web3D and SIGGRAPH registration independent of each other.
SIGGRAPH 2019
https://s2019.siggraph.org
Communications team meets weekly to continue promoting Web3D, X3D and HAnim.

7. *Upcoming topics*
Next week: TBD (Don traveling)
- Projective Texture Mapping (PTM) component.
a. Mantis issue 1255 created for keeping track of status.
b. TODO Add zip of spec/examples/information that has been submitted on mantis issue
http://www.web3d.org/member-only/mantis/view.php?id=1255
c. Prose already present in github components directory as ProjectiveTextureMapping.html
43 Projective Texture Mapping Component
https://github.com/Web3DConsortium/X3D/blob/master/ISO-IEC19775/ISO-IEC19775-1/ISO-IEC19775-1v4.0/ISO-IEC19775-1v4-WD1/Part01/components/ProjectiveTextureMapping.html
d. TODO Add example scenes to X3D Basic Examples Archive
e. TODO List existing implementations, then issue call for additional implementations.
Topics list:
- Annotation Component:
a. Much work already accomplished. Renewed review in Design Printing Scanning (DPS) group.
b. Time to land any existing draft prose in github specifications, and review what work is occurring.
- X3D Architecture Design and Event Passing, compare implementations. Specification writeup planned late May.
a. how have X3DOM and X_ITE each implemented events?
b. What differences exist?
c. Are ROUTE connections consistent?
d. X3DOM is still missing some important/simple Event Utility nodes - is there a problem?
e. Highlight how does syntax disambiguate handling of HTML5 Script and X3D Script?
f. Reviewing our tagging of Mantis issues as #X3Dv4 for completeness.
g. Ensure that goals and concepts on relationships between HTML5 and x3D are clearly expressed.
- MetadataSet containerField implementation efforts, Mantis issue resolution
- Tagging and prioritizing Mantis issues.
- Numerous things to drive to completion, who is doing what? Now listed on X3Dv4 Implementations page.
- Sound and Audio implements
Related work:
- X3D and other BOFs at SIGGRAPH, how to best execute these? Anita is driving.
- Carto BOF, are there any candidates for that? So far, none.
- X3DOM release status? Expected for Web3D 2019.
==================================
No major showstoppers are noted, rather we continue getting closer to a comprehensive X3Dv4-HTML5 architecture each week.
Steadily progressing with X3Dv4! 8)
all the best, Don
