Agenda for today.  The first two items are expected to proceed rapidly so that we can get to the critical-path challenge.

1. Conference preparations

[1] Web3D 2020 Conference
     https://web3d.siggraph.org

Building out program for accepted content.  Registration open soon, No Cost!

---

2. Change reference urls for X3D DOCTYPE, XML Schema to https

[2.1] X3D Scene Authoring Hints, Validation of X3D Scenes using DTD and XML Schema
       https://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Validation

[2.2] [x3d-public] X3D DOCTYPE problem; X3D Validator has workaround, necessary path forward confirmed;
       fixed, upgrade path proposed
       https://web3d.org/pipermail/x3d-public_web3d.org/2020-September/013622.html

As before: any objections?

3. Resolution of X3D4 node signature changes for advanced Material texturing techniques

Special thanks to Michalis Kamburelis and Andreas Plesch for steady efforts on this challenge.  Looks like we are close to resolution.

[3.1] [x3d-public] wondering about Texture mapping specified in material nodes,
       X3D4 usage tradeoffs and draft meeting agenda
       https://web3d.org/pipermail/x3d-public_web3d.org/2020-September/013651.html

[3.2] [x3d-public] wondering about Texture mapping specified in material nodes,
       X3D4 usage tradeoffs and draft meeting agenda (review summary)
       http://web3d.org/pipermail/x3d-public_web3d.org/2020-September/013658.html

[3.3] Proposal: Change mapping concept into a number of xxxTexCoord fields in geometry
       https://github.com/michaliskambi/x3d-tests/wiki/Proposal:-Change-mapping-concept-into-a-number-of-xxxTexCoord-fields-in-geometry

[3.4] Proposal: wrap index values in a new node
       https://github.com/michaliskambi/x3d-tests/wiki/Proposal:-wrap-index-values-in-a-new-node

[3.5] X3D4 Working Draft 2 (WD2) Shape Component
       https://www.web3d.org/specifications/X3Dv4Draft/ISO-IEC19775-1v4-WD2/Part01/components/shape.html
       
Objectives today:

a. review of tradeoffs.

b. identify next changes to X3D4 spec.

c. identify remaining technical design and implementation issues, if any.

all the best, Don
