0. Review of prior meeting minutes.

1. X3D Specification Relationships diagram update.

Nontrivial refactoring proposed for X3D v4, all feedback and discussion welcome.

2. Updates posted that essentially complete X3D regexes for all basic types, adding SFImage/MFImage and the Matrix types.  regex101 unit tests all pass. Some further X3DJSAIL unit testing in progress, but it looks like the regexes are working and integrated X3DUOM.  Getting all of these fully vetted will be another major step forward for X3D Quality Assurance (QA).

3. Close scrutiny of X3D ECMAScript (JavaScript) language binding draft revealed a number of problems today.  Our efforts as ISO editors continues.  Feedback from X3D browser and player implementers welcome.

	[x3d] x3d ecmascript 19977-1 spec review; problems found

4. Further discussion.
- more siggraph events review
- more spec planning
- possibly glTF, tech topic TBD

5. TODO: Projective Texture Mapping (PTM) component.

6. TODO: enter Mantis issue documenting dialog/threads regarding LocalFog, including Michalis' excellent analysis.  This node still has important clarity and functionality gaps that prevent greater utility.  I suspect there is a potential future improvement for X3D v4.

7. Update releases, after a hiatus:

	X3D-Edit 3.3 open-source Extensible 3D (X3D) Graphics authoring tool
	https://savage.nps.edu/X3D-Edit

including refresh to

	NPS branch of Xj3D
	https://savage.nps.edu/Savage/developers.html#Xj3D

8. All other topics welcome.  Have fun with X3D!

all the best, Don
