[x3d-public] announce: updated release for X3D Java Scene Access Interface Library (X3DJSAIL)

[Brutzman, Donald (Don) (CIV)]

Am happy to report an updated release of the X3D Java Scene Access Interface
Library (X3DJSAIL).  This open-source capability is tested using the latest
version of Java OpenJDK 20.0.2.

 

*	X3D Java Scene Access Interface Library (X3DJSAIL) supports
programmers with standards-based X3D Java interfaces and objects, all as
open source.
*	https://www.web3d.org/specifications/java/X3DJSAIL.html
*	https://www.web3d.org/specifications/java/javadoc

 

Improvements in this release include better handling of Humanoid Animation
(HAnim) model structured relationships, along with terser and more precise
diagnostics when validating X3D models.  Improved X3dToHtml stylesheet
production of event-graph documentation has also been updated.

 

Strong typing of data structures makes high-reliability production of X3D
models using Java possible.

 

*	X3DJSAIL is a set of strongly typed Java application programming
interfaces (APIs) providing programmer access to an X3D scene graph. 
*	Two integrated Java packages are included that contain X3D SAI
interfaces and support the X3D Graphics Standards for Java programmers.

*	org.web3d.x3d.jsail   provides concrete implementation-oriented
classes for building X3D scenes using standalone Java objects.
*	org.web3d.x3d.sai     contains standard X3D SAI interfaces to
independently compile Script-node source for use in X3D players.

 

Goal outcomes: make it easy to create a fully valid X3D scene graph using
Java, while also making it hard to create an incorrect or invalid X3D model.

 

*	Software design patterns are autogenerated from rigorous definitions
of all X3D node and field relationships using the X3D Unified Object Model
(X3DUOM). 
*	Validation of individual fields includes application of X3D Regular
Expressions (regexes). 
*	X3DJSAIL Javadoc includes all descriptions, links, hints, and
warnings from the X3D Tooltips. 

This library successfully supports multiple purposes.

*	Create high-performance standalone Java applications using a Plain
Old Java Object (POJO) implementation for X3D.
*	Such X3D-capable Java applications can be client-based,
server-based, or driven via command-line invocation (CLI) such as Java
Console (jconsole).
*	Test ongoing deployment of X3D version 4 while maintaining full
support for prior X3D versions 3.0 through 3.3.

Over 4000 models in the X3D Examples Archive continue to be used as a source
for conversions, regression testing and further improvements. 

 

*	X3D Resources, Examples: Scene Archives for X3D
*	The X3D Examples Archives demonstrate how X3D nodes and scenes work.
Thousands of scenes are provided in all X3D encodings. You can browse them
individually online or download fully complete, separately installable .zip
archives. Links to thousands of additional X3D example scenes are provided.

Comprehensive build logs show current results.  Issue reports and feature
suggestions are welcome.

Have fun with X3D and Java using X3DJSAIL!  8)

 

all the best, Don
