<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.

<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_5367448738452837218moz-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

<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">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"><u></u> <u></u></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"><u></u> <u></u></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"><u></u> <u></u></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"><u></u> <u></u></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>
