<p>I think I begin to understand what is happening beneath the

<p>I could partly succeeded in X3D file output with
X3D0.setScene(Scene25)</p>
<p> from your HelloWorld.py for the functions already implemented
(by pynius?) as attached.</p>
<p>Hopefully, missing functions are to be implemented soon.</p>

<p class="MsoNormal">Thank you for meeting today
to discuss X3D Object Model transformation by
applying an XSLT stylesheet to autogenerate of
SAI codebases.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Myeong Won Lee, I also
thought that your Unity HAnim player is
wonderful. I recommend that you include some
examples in the public release, they will
generate strong interest. Having some public
examples while also allowing private examples
provides appealing choices and the best possible
support for your students.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Here is summary excerpted
from this week's Web3D meeting report.</p>
<p class="MsoNormal">==============================<wbr>==============================<wbr>====</p>
<p class="MsoNormal">3. Object Model
for X3D (OM4X3D)</p>
<p class="MsoNormal">a. The Object
Model for X3D (OM4X3D) is a full set of
object-oriented interfaces for all nodes, fields
and statements in the X3D Abstract
Specification.</p>
<p class="MsoNormal">b. OM4X3D is
produced by decorating the X3D XML Schema with
carefully structured annotations that describe
the entire object-oriented nature of the X3D
scene graph. <a class="m_3774458644941123831m_-7894946465718207821moz-txt-link-freetext" href="http://www.web3d.org/specifications/OM4X3D/ObjectModelForX3dCreation.png" target="_blank">http://www.web3d.org/specifica<wbr>tions/OM4X3D/ObjectModelForX3d<wbr>Creation.png</a></p>
<p class="MsoNormal">c. Instantiation:
Object Model for X3D definitions are explicitly
listed in X3DObjectModel 3.3.xml with
corresponding XML schema x3dObjectModel.xsd</p>
<p class="MsoNormal">d. Ongoing
public/private dialog using the <a class="m_3774458644941123831m_-7894946465718207821moz-txt-link-abbreviated" href="mailto:x3d-public@web3D.org" target="_blank">x3d-public@web3D.org</a>
mailing list and presentation at Web3D 2017
Conference has been productive.

<p class="MsoNormal">e. Demonstration
of strict object model in X3D JSON Encoding,
which is 98% complete and undergoing extensive
review and testing, initial-draft specification
has been prepared.</p>
<p class="MsoNormal">f. Initial
implementations are available in JavaScript,
Java, and C++. Also planning to prepare
programming-language implementations for C, C#.</p>
<p class="MsoNormal">g. Two new
versions for Python are started, with dialog
occurring to discern best practices.</p>
<p class="MsoNormal">h. SAI no longer
just Script node in Browser object, includes
full application-oriented API. This will lead
to some changes and generalizations in 19775-2
Abstract SAI specification.</p>
<p class="MsoNormal">i. Multiple
emerging SAI specifications and implementations
are shown on updated draft X3D Specifications
Relationships diagram (attached)</p>
<p class="MsoNormal">j.
Implementation: X3D JSON Loader (X3DJSONLD) <a class="m_3774458644941123831m_-7894946465718207821moz-txt-link-freetext" href="https://github.com/coderextreme/X3DJSONLD" target="_blank">https://github.com/coderextrem<wbr>e/X3DJSONLD</a></p>
<p class="MsoNormal">k. Implementation:
X3D Java Scene Access Interface Library
(X3DJSAIL)
<a class="m_3774458644941123831m_-7894946465718207821moz-txt-link-freetext" href="http://www.web3d.org/specifications/java/X3dJavaSceneAuthoringInterface.html" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/X3dJavaSceneAuthori<wbr>ngInterface.html</a></p>
<p class="MsoNormal">l. Under
consideration: integration into X3D Abstract
Specification 19775-1 to more thoroughly expand
on current abstract interface hierarchy.</p>
<p class="MsoNormal">m. Emerging
capability: coherent X3D center, multiple
different programming languages that offer
common design patterns to programmers to create
identical scene graphs.</p>
<p class="MsoNormal">==============================<wbr>==============================<wbr>====</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">The essence of autogeneration
is that proper code patterns must first exist.
Once we get a few classes with the design
patterns of interest, and generation of a few
classes, then creation of all classes follows in
a straightforward manner.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I recommend that the first
example we work with is HelloWorld.x3d into .c
.cpp .cs and .py source.</p>
<p class="MsoNormal"> <a class="m_3774458644941123831m_-7894946465718207821moz-txt-link-freetext" href="http://www.web3d.org/x3d/content/examples/HelloWorld.x3d" target="_blank">http://www.web3d.org/x3d/conte<wbr>nt/examples/HelloWorld.x3d</a></p>

<p class="MsoNormal"> </p>
<p class="MsoNormal">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.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Next steps for Python:
recommend that we</p>
<p class="MsoNormal">- Examine Masaki's work and
compare it with the pyjnius conversions.</p>
<p class="MsoNormal">- Autogenerate Python library
(X3DPSAIL perhaps?) to provide Python codebase
support.</p>
<p class="MsoNormal">- Iterate until we have a
good design pattern for HelloWorld and other
exemplars.</p>
<p class="MsoNormal">- Create an X3dToPython.xslt
stylesheet that can convert someModel.x3d to
someModel.py source.</p>
<p class="MsoNormal">- run that across all scenes
X3D Example Archives, detect and resolve errors,
publish builds.</p>
<p class="MsoNormal">- make T-shirts 8)</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">As with JavaScript and Java,
it is good to use the x3d-public list for this
work. Also suitable for a weekly update reports
and monthly telcon item for X3D Working Group.</p>
