[x3d-public] X3D example to show x3d.py on the web?

Wed Dec 28 01:07:44 PST 2022

In is interesting how the brython library extends Python for use as an HTML
script language.

John, wondering if your original Web3dLogo-X3d-animated-logo2.x3d model is
available for comparison?

all the best, Don

Success!  I was able to get Web3dLogo-X3d-animated-logo3.py (with my
modifications) working on the web with brython.

Attached are the two updated files in a zip.

Here is the whole project, perhaps minus some python packages.

Thanks for feedback.

Note, x3djsonld.py does not work yet!

There are issues thrown against the generated files from X3dToPython.xslt
and X3dToJson.xslt, if I'm reading this right.  Actually, I just checked the
source file against the X3D validator, and there appear to be multiple
issues!

Please fix the .x3d in your original zip, Joe!

Attaching files.

I'm going to set this aside for now, but the last thing I will do is check
the XML

Web3dLogo-X3d-animated-logo2.zip has the bad .x3d file!

Thanks!

Does anyone have an x3d example they'd like to convert to Python and display
on the web?

I'd like a beefier example than "HelloWorld.py". since that's been done.

It should be compatible with X3DOM and x3d.py.

You'll get a python file and an HTML file back.

I trust you will be experienced enough to install brython locally.   I will
take a video  and post on YouTube.

Thanks!

John
