[x3d-public] native Python package for X3D

[Brutzman, Donald (Don) (CIV)]

Have started work, initial build harness is in place.

Am generating from X3DUOM via stylesheet, in x3d stylesheets subdirectory 'python' at same level as subdirectory 'java' for X3DJSAIL.

http://www.web3d.org/x3d/stylesheets/build.xml
ant target BuildX3dPythonPackageFromX3duom.saxon

using stylesheet
http://www.web3d.org/x3d/stylesheets/X3duomToX3dPythonPackage.xslt

producing
http://www.web3d.org/x3d/stylesheets/python/X3dPythonPackage.py

version control:

https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/stylesheets/
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/stylesheets/build.xml
https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/stylesheets/X3duomToX3dPythonPackage.xslt

https://sourceforge.net/p/x3d/code/HEAD/tree/www.web3d.org/x3d/stylesheets/python/X3dPythonPackage.py

So far have simplistic entries for field types, nodes and statements.  Excerpts:

     def __init__(self, **kwargs):
         pass

Will work on simple-type fields as properties next, adapting patterns from Python Cookbook.

all the best, Don
