We have accomplished
in the pyjnius folder, but perhaps not in the examples/* folders.
but we haven’t packaged it. The classpath is critical to this. I believe this has been solved for mybinder, but not for pip or conda.
Andreas is close to packaging for conda with his mybinder.
Scyjava is one way of creating a conda package and configuring the java classpath. Seems like overkill, as does a maven repo. We should document how to put a jar into a local maven repo.
I’ve been sleeping, sorry!
Andreas has been providing very useful information re mybinder.
I have a x3dpsail GitHub repository. Give me your email/username if you want to be added to it. It is out of date.
I don’t think we should put everything from our pyjnius folder into x3dpsail.

Sorry to miss much of this, am replying when able.
Summary of status:
a. We are quite close to a usable X3D Python language capability.
b. There are .py programs published online for each scene in X3D Examples archive.
c. John has at least two translators .x3d -> .py source.
d. X3DPSAIL is our name for the pyjnius python implementation that applies X3DJSAIL classes.
e. The first translator uses field-object casting (e.g. SFFloat(1.0)) and works.
f. The second translator is terser and more desirable but provokes pyjnius return-type errors, such as those below.
g. The second translator output is published online and almost exactly matches the .java which uses X3DJSAIL. So we know that the underlying X3DJSAIL java calls can work if properly invoked by pyjnius.
h. We have fixed the ability of Python to use double-precision values for X3D SFloat fields.
i. We are working on how to move the various import statements out of source programs and into pyjnius mappings.
j. We steadily continue to test and improve. All questions and suggestions are welcome.
We desperately need an X3DPSAIL.html page with this information. Too busy debugging, hopefully will write it soon. Thanks for your attention and insights!
