X3D Java Scene Access Interface Library (X3DJSAIL) supports programmers with standards-based X3D Java interfaces and objects, all as open source.

X3DJSAIL provides 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. X3DJSAIL has succeeded in accomplishing these goals.

• 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 custom Javadoc includes all descriptions, links, hints, and warnings from the X3D Tooltips.

Available products include Javadoc documentation, several thousand self-validating examples, source code, build support, run-time jar archives, and draft specification annexes for node interfaces and abstract-node type interfaces.

Questions, suggestions, additions and comments regarding the X3D Java SAI Library (X3DJSAIL) and X3D Unified Object Model (X3DUOM) design are welcome. Please send them to Don Brutzman (brutzman at nps.edu).
