[X3D-Ecosystem] Installation of X3DPSAIL into Blender

[Vincent Marchetti]

Question raised below
> How do you install X3DPSAIL in Blender?
I am assuming this is equivalent to importing the PyPI x3d package.


Somewhere in the Blender installation there is a python executable, in my Blender 4.2 installation its location, relative to the Blender executable, is

../Resources/4.2/python/python/bin/python3.11

You can run something like
PYTHON -m pip x3d 
; where PYTHON should be an absolute or PATH accessible reference to that executable, to install x3d in Blender’s Python installed packages.

However, what people usually actually want to do is to install a 3rd party package along with their own add-on that uses that library. There are on the web dark and mysterious hacks to accomplish this, but the real answer, as you point out, that you include the source code for that 3rd party package in the add-on code.

So if we wish to modify the standard X3D import/export extension to use some feature of the x3d package, we need to add the x3d.py file to the code visible at https://projects.blender.org/extensions/io_scene_x3d/src/branch/main/source 

In your client code you then have to import the x3d package using relative import addressing.
