Thu May 9 10:16:43 PDT 2019
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:
The X3D Graphics Working Group addresses all X3D specification issues and coordinates the technical development of future improvements.
Each week we report out both public and member-only information - membership has value. To become a Web3D Consortium member:
Join the Web3D Consortium
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
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
[x3d-public] X3D Python availability, planning for releases at Web3D 2019
"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:
- 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.
Web3D and SIGGRAPH registration independent of each other.
Communications team meets weekly to continue promoting Web3D, X3D and HAnim.
6. *References and Resources*
X3Dv4 Implementations Status
X3Dv4 Development page
X3D Specification Relationships
Mantis Issues (requires member login, twice)
Web3D Specifications on Github: X3D (members can request access)
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
c. Prose already present in github components directory as ProjectiveTextureMapping.html
43 Projective Texture Mapping Component
d. TODO Add example scenes to X3D Basic Examples Archive
e. TODO List existing implementations, then issue call for additional implementations.
- 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
- 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
