[x3d-public] Repairing this Jupyter Notebook is a pain!

[Vincent Marchetti]

A problem with the Jupyter notebook attached in this email was that the entire XML document, including the <xml...> declaration, was inserted into the <x3d> node for X3DOM to interpret, and that failed.

There seem to be as many ways of inserting an <x3d> node for X3DOM into an notebook as there are authors, but the method I use is illustrated at

https://github.com/vincentmarchetti/web3d2021_jupyter_tutorial/blob/main/HelloWorld.ipynb 

which is an attempt at illustrating the intent of John's notebook, to prepare the HelloWorld scene using the X3D python module, and then to render it in the notebook.

I did note two problems in fully rendering the HelloWorld scene, pertaining to loading the image texture from the web3d.org site
1. X3DOM only tries the first URL in the ImageTexture url field
2. Even if the web3d.org url is put first, the web3d.org server is not configured to support the strict CORS protocol. As a result, the Firefox brower will retrieve the the image from web3d.org, but will not allow the x3dom code to see that data.

The notebook referenced above from github will render the earth as a sphere and show the text in the X3D scene.
