- Rename Humanoid Animation (HAnim) simpleType enumeration lists for clarity:<br>
featurePointNameValues -> hanimFeaturePointNameValues<br>
segmentNameValues -> hanimSegmentNameValues<br>
jointNameValues -> hanimJointNameValues<br>
- (v4.0) add displayBBox field to X3DBoundedObject, Mantis 1277<br>
- (v4.0) rename isPickable as pickable for naming consistency, Mantis 1287<br>
- (v4.0) X3DLayerNode, Layer, LayoutLayer implements X3DPickableObject with<br>
fields objectType pickable and visible, Mantis 1287<br>
<br>
- TODO (v4.0) CollisionCollection contains nodes with X3DBoundedObject interfaces, so<br>
TODO CollisionCollection needs to be marked in specification as X3DBoundedObject as well.<br>
- TODO (v4.0) PointSet, LineSet, IndexedLineSet implement X3DComposedGeometryNode<br>
similar to other geometry nodes, allowing Normal and texture coordinate children<br>
- TODO HAnimJoint inherits X3DGroupingNode but interfaces aren't directly defined,<br>
bugfix needed in X3DUOM<br>

b. *X3DUOM*<br>
<br>
The X3D Unified Object Model (X3DUOM) is a full set of object-oriented interfaces for all nodes, fields and statements in the X3D Architecture Specification.<br>

c. *X3DJSAIL Java*<br>
<br>
X3D Java Scene Access Interface Library (X3DJSAIL) supports programmers with standards-based X3D Java interfaces and objects, all as open source.<br>
<br>
<a href="https://www.web3d.org/specifications/java/X3DJSAIL.html" rel="noreferrer" target="_blank">https://www.web3d.org/specifications/java/X3DJSAIL.html</a><br>
<br>
X3DJSAIL tests under Oracle Java 14 testing is satisfactory for under Apache Netbeans 11.3 (new release). Further testing is showing latest OpenJDK to be fully robust. Recent upgrade to Ant also worked fine. Compiled bytecode is maintained at Java 8 for maximum interoperability.<br>
<br>
Example smoke tests and unit tests are maintained as follows. Keeping logs in version control provides a robust diagnostics whenever outputs change.<br>

f. *Python X3D Language Binding*<br>
<br>
"The x3d.py Python X3D Package supports programmers with Python interfaces and objects for standards-based X3D programming, all as open source."<br>

<br>
Approximately 3950 X3D Examples have been converted to python, then loaded to perform self checks. The vast majority pass, bug tracking continues.<br>

<br>
Improvements continue with current focus on confirming correct .x3d export with other encodings to follow. Effective PyPi distribution can eventually lead to Jupyter Notebook, Anaconda and Apache Zeppelin distributions too, so there will be no shortage of future Python X3D work to pursue!<br>

<br>
e. *X3D Tooltips*<br>
<br>
X3D Tooltips are frequently checked for correctness and used as part of X3DJSAIL Javadoc. They are convenient place to "check first" for questions since entries for each node and field have numerous links to all related specifications, resources and documentation.<br>
<br>
Extensible 3D (X3D) 3.3 Tooltips (with X3D version 4.0 draft)<br>

<br>
Questions and answers for X3D usage on the x3d-public mailing list often lead to hints and warnings. Thanks for all suggestions.<br>
