[x3d-public] X3D meeting agenda 4 FEB 2022: Rigid Body Physics review, Projects Wish List, X3D implementation spreadsheet

[John Carlson]

Most of this has been discussed on the mailing list already, so if you’ve
been reading me already, by all means skip this email.

Status report.

Hi Don.  I am continuing to document JSON schema generating rules in hopes
of creating an XSLT version in the future, perhaps.  I still need to
document the field generator and maybe mess with indentation.   If I get
home Monday from the doctor, etc, we can review, perhaps.  I am having no
issues understanding the python, thank goodness.  I will work on getting
the python into publishable form.

As far as C/C++/C# SAI, I have a filter which takes the <pre> text sections
out of the C++ working draft, but there’s still a lot of work to do.
Ideally we would create a XSLT where we could easily extract c++ data
structures from X3DUOM without extra fiddling.  I posted a request to
semantics-public requesting a SPARQL query runnable from python to gather
dependencies for a C++ class.  Also, the C++ HTML code (I haven’t
investigated rendering yet) includes duplicate member functions (class
field at least), which should be addressed or recognized.   This was pretty
much on the first class I looked at, so I’m guessing there’s more lurking.
  I will continue working on the C++ after documenting JSON schema.  Slowly
plogging along, but wrists are less pained, so that’s a bonus.   Python
code (beautifulsoup) has been posted.   XSLT has not.

When perusing the C++ interfaces HTML docs, I noticed multiple references
to Java, so that should probably be addressed.

 X3DJSONLD and JSON to STL has been placed on a back burner for now.   I am
seeking coworking opportunities, particularly a mathematician/geometer who
can help with tessellation PROTOs for spheres, cones, cylinders, etc.
Anyone?

It would be advantageous to me if someone could point out good Node.js
packages for querying XML with some examples.  I know of querySelector and
querySelectorAll in HTML/CSS JavaScript.

If someone has had good results with copilot/codex/gpt-3, please share!
