0. *Agenda*
Today's goal: PointProperties is in draft X3Dv4 specification, issue call for implementation support of remaining steps.
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.
TODO each meeting: confirm all information in weekly minutes is releasable publicly. One separate member-only message was sent last week.
----
Members and invited experts are welcome. We are an open organization.
We meet regularly on Fridays 0800-0930 pacific. To join the teleconference:
Web3D 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:

==================================
1. *Prior meeting minutes*
X3D minutes 5 APR 2019: X3Dv4 progress review, PointProperties inserted in github
http://web3d.org/pipermail/x3d-public_web3d.org/2019-April/010473.html
X3D minutes 15 MAR 2019: advanced humanoids discussion; X3Dv4 specification editing
http://web3d.org/pipermail/x3d-public_web3d.org/2019-March/010320.html
At this point we discuss recent meetings and current developments.
a. Dick has applied additional comments on HAnim FDIS from ISO editors - hopefully the final set - we will meet to resolve them.
b. Issue discussed in CAD working group: recent SC4 approval of JTOpen didn't seem to include much SC24 review, may need need to look at it further in SC24. We hope to maximize our interoperability via Joint Working Group there. Christophe, Soonhung Han, Dick Puk and I will track this issue to see if further followups are needed. Request update on status that this is now being tracked.
Agenda review: what else?
==================================
2. *Recent and Upcoming Events*
Several important external events relating to X3D have occurred. Significant valuable resources are online that are worth quick review. Expect to see further twitter announcements on these.

d. Cancelled, made event announcement inactive:
First Eurographics-EuroVR Workshop on Semantic 3D Content
http://www.web3d.org/event/first-eurographics-eurovr-workshop-semantic-3d-content
X3D Semantic Web Working Group is circulating draft workshop submission for Web3D 2019 to ascertain participation commitments.
e. In preparation: Web3D 2019 Conference
http://www.web3d.org/event/web3d-conference-2019
http://web3d2019.web3d.org
f. SIGGRAPH 2019
https://s2019.siggraph.org
Communications team meets weekly to continue promoting Web3D, X3D and HAnim.
==================================
3. *Status of X3D Language Bindings and File Encodings*
TODO: refresh
a. Humanoid Animation (HAnim)
- HAnim specifications are a closely related ISO standard
- FDIS submitted to ISO, final comment resolution in progress.
- New zip available to members containing both volumes together.
- HAnim version 2 is included already in X3Dv4
- Active work on implementing in X3Dv4 by Joe Williams and Don Brutzman
b. X3D Java language binding
- Build outputs now in version control, available at
http://www.web3d.org/x3d/content/examples/build.java.all.log.txt
- Stable, complete and working using
X3DJSAIL: X3D Java Scene Access Interface Library
http://www.web3d.org/specifications/java/X3DJSAIL.html
- TODO: review and update Java specification
c. JSON encoding for X3D
- Build outputs now in version control, available at
http://www.web3d.org/x3d/content/examples/build.json.all.log.txt
- X3DJSONLD summary, status
- JSON Schema updata
https://json-schema.org still at draft-07
JSON Schema is a vocabulary that allows you to annotate and validate JSON documents.
"Update as of 31 March 2019. You may be wondering what in the world is going on with this draft? The short version is: we are entering the home stretch. There are some ideas for simplifying $id that we are considering, and then there will be a final review period for feedback on overall flow and clarity. [...] We expect to publish a new round of drafts (Core, Validation, Hyper-Schema, Relative JSON Pointer) in the next month or two" [...]
- TODO: update X3D JSON schema to match next version, then autogenerate from X3DUOM
- TODO: create X3D JSON specification
d. X3D C, C++, C# Language Bindings
- Last reviews at Web3D Korea Chapter meeting Seoul January 2019
- TODO update status, plans for SIGGRAPH code releases and encouraging additional use.
- TODO: create specifications
e. X3D Python Language Binding
- active work implementing by John Carlson and Don Brutzman
- TODO applying build to all X3D examples, then tuning syntax
- TODO writeup implementation capabilities and then create specification
f. X3DUOM: X3D Unified Object Model (X3DUOM)
X3DUOM is a full set of object-oriented interfaces for all nodes, fields and statements in the X3D Architecture Specification.
http://www.web3d.org/specifications/X3DUOM.html
==================================
4. *PointProperties*
Task completed today: review Mantis issue, place prose into Github repository.
Mantis 1252: Prepare specification prose for a PointProperties node
http://www.web3d.org/member-only/mantis/view.php?id=1252
https://github.com/Web3DConsortium/X3D
(note link on README)
https://github.com/Web3DConsortium/X3D/tree/master/ISO-IEC19775/ISO-IEC19775-1/ISO-IEC19775-1v4.0/ISO-IEC19775-1v4-WD1/Part01
then specification paragraph 12.4.5 PointProperties
https://github.com/Web3DConsortium/X3D/blob/master/ISO-IEC19775/ISO-IEC19775-1/ISO-IEC19775-1v4.0/ISO-IEC19775-1v4-WD1/Part01/components/shape.html
Dick and I have have transcribed the Mantis issue prose into the draft specification. This will be good to review during next week's CAD call.

https://github.com/Web3DConsortium/X3D
Communication of priorities is welcome. We will focus on one or two topics every week.
==================================
6. *Upcoming topics*
- X3D Architecture Design and Event Passing, compare implementations
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?
- Projective Texture Mapping component next week?
- MetadataSet implementation efforts
- Tagging and prioritizing Mantis issues.
- Numerous things to drive to completion, who is doing what?
TODO:
- X3D and other BOFs at SIGGRAPH, discussion Monday.
- Carto BOF, are there any candidates for that?
- X3DOM release status
==================================
No major showstoppers are noted, rather we continue getting closer to a comprehensive X3Dv4-HTML5 architecture each time.
Having fun with X3Dv4! 8)
all the best, Don
