a. CADExchanger adds import to export support.

[1] #X3D support in @CADExchanger SDK 3.8.1:
     new version supports not only export but also import of #X3D.
     Now possible to view and explore the files and convert them to
     #VRML, OBJ, STL, and many other formats.

3. X3D Programming Language Bindings for C/C++/C#

There is renewed interest in pursuing X3D implementations in C, C++ and C# programming languages.

Summary of plans and possibilities, building on 2018 strategy which continues to slowly percolate.

[5] C/C++/C# X3DSAIL
     http://web3d.org/pipermail/x3d-public_web3d.org/2020-August/013403.html

We discussed whether C-related language bindings can support scripting.  If they can only support external access, that should be noted in the language binding.  Many languages have added on-the-fly compilation, we need to look further at that.

We also discussed how abstract SAI Architecture was designed to handle both Script nodes internal to X3D scene graph, as well as standalone X3D usage.  It will be interesting to see if SAI specification might need some additions to support all the functionality available in X3D4 and these other programming languages.

TODO:
- schedule meeting with Dr. Myeong Won Lee to review her contributions and draft specification,
- Don will help match best patterns to autogeneration of those codebases, and
- Most important: we are looking for C/C++/C# gurus who can comment and possibly improve the SAI design patterns.

4. Coming up.

a. X3D Physically Based Rendering PBR review with Michalis Kamburelis.  Close look at specification prose and Inline.
b. X3D Sound Component and Web Audio API: updated examples, building audio graph with Efi Lakka and Thanos Malamos.
c. X3D C/C++/C# Bindings with Myeong Won Lee.
d. X3DOM implementation support for Prototype and Script (x3dscript?) with Andreas Plesch, then
e. harmonize/document X3DOM/X_ITE approaches in writeup for X3D4/HTML5 integration.
f. Possible HAnim Next workshop as part of Web3D 2020 Conference, adding human internal organs and facial expressions.
    Hoping to line up work for delivery next summer.
g. How to incorporate X3DUOM and X3D Ontology prose in X3D set of standards.

5. ISO SC24 Annual Meeting

Nearly complete.  Drafting final resolutions today, final plenary Monday, reports to Web3D Board (and eventually public) to follow.  Dick Puk is our Working Group 6 convener, Myeong Won Lee is SC24 chair, I am Web3D Consortium Liaison, multiple other Web3D Consortium members are also attending as part of their respective national bodies.

Thanks for all efforts.  Have fun with X3D!  8)

all the best, Don
