<p>Dear John<br>
</p>
I'd appreciate your continuous efforts for the bridge between Java
and Python.<br>
<br>
<br>
I may be wrong., but I believe the number such as 4278190335 is too
large for 32-bit integer.<br>
This is where I think NumPy's 64-bit integer may be needed for
compatibility (with Java's long)<br>

<br>
I mean wherever Java's long integer is expected,<br>
Numpy's int64 might be of help.<br>

everyone for looking at my code. I think the issue
might be a previous set() function defined in the
interface returns the interface class type, and then a
new set function is called on the interface. This can
be checked by separating the calls to set...() functions
into separate calls on the numbered on the numbered
object, so they are not chained together. This can be
tested by hand modifying HelloWorld.py and removing the
chaining and putting each set() call in a separate
statement. I will try to modify my serializer to do
this when I get the chance. I believe a previous

<p class="MsoNormal" style="margin-left:1.7in"><span style="color:black">Regarding
Python: John Carlson
has done intriguing
work that
auto-translates Java
source in X3DJSAIL
to Python. This is
interesting because
it would keep the
codebases closely
aligned, making it
easier to learn and
debug. Consistency
is easily maintained
across X3D versions
and X3D bugfixes by
re-running each
distribution.
Flexibility is also
possible since each
codebase will
include custom
utility classes,
methods and
examples.<u></u><u></u></span></p>
