[x3d-public] X3D minutes 24 March 2022: continuing Mantis issues review

[Brutzman, Donald (Don) (CIV)]

Attendees:  Anita Havele, Nicholas Polys, Dick Puk, Don Brutzman

 

We had a good discussion about opportunities with geospatial, medical and
other X3D components.

 

Again emphasized - X3D4 is done!  All functionality is complete.  Current
editorial efforts are simply buffing and polishing the document for ISO,
people should not hesitate to use it.

 

We came up with some useful clarifications today, resolving  a total of 10
Mantis issues this week.  Of note today:

 

*	Mantis 878: 13.3.4 ElevationGrid - No explicit statement of
row-major order
*	https://www.web3d.org/member-only/mantis/view.php?id=878
*	X3D4 Architecture, Geometry3D component, ElevationGrid
*	Added “The height array values are given in row-major order from
left to right along the X axis, then back to front along the Z axis.”
*	https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1
/Part01/components/geometry3D.html#ElevationGrid

 

and

 

*	Mantis 873: 22.3.1 X3DEnvironmentalSensorNode - size field incorrect
minimum value
*	https://www.web3d.org/member-only/mantis/view.php?id=873
*	X3D4 Architecture, Environmental sensor component, 22.3.1
X3DEnvironmentalSensorNode
*	Set field signature as SFVec3f   [in,out] size        0 0 0  (-∞,
∞)[0,∞)
*	Added “The center field defines the center location of the
specified sensor volume.”
*	Added “The size field defines the effective volume of the sensor. A
default value of 0 0 0 means that the sensor has no active volume and is
essentially disabled.”
*	https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1
/Part01/components/environmentalSensor.html#X3DEnvironmentalSensorNode

 

Special thanks to Roy Walmsley for reporting these two issues and many
others.

 

Have fun with X3D!

 

all the best, Don

Subject: X3D agenda 24 March 2022: continuing Mantis issues review

 

1.	For our weekly X3D teleconference Friday 08-0900, Dick and I plan to
continue efforts resolving Mantis editorial issues for X3D4.  At this moment
we have  another 25 issues with draft changes applied for final review.

 

*	Web3D Consortium Mantis Issue Tracker
*	https://www.web3d.org/member-only/mantis/view_all_bug_page.php

 

*	X3D4 Architecture Draft Specification
*	https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-CD1
/Part01/Architecture.html

 

*	What is X3D
*	https://www.web3d.org/x3d/what-x3d

 

All remaining document issues are editorial - X3D4 modeling and presentation
is available today, with steady progress among multiple implementations.

 

2.	Still unanswered is a request to geospatial experts for a focused
one-hour meeting reviewing X3D Geospatial issues.  We request their insight
as we resolve, reject or defer geospatial issues to future X3D4.1 efforts.

 

Have fun with X3D!   8)

 

all the best, Don
