[x3d-public] announce: X3D Java Scene Authoring Interface (SAI) open source, beta supports ClassicVrml and VRML97 encodings

[Don Brutzman]

1. Continuing progress, daily build updates have been getting posted for

	X3D Java Scene Access Interface (SAI) Library
	http://www.web3d.org/specifications/java/X3dJavaSceneAuthoringInterface.html

	http://www.web3d.org/specifications/java/javadoc

Recent additions:

Complete. Support for X3D .xml, ClassicVrml .x3dv and VRML97 .wrl output file encodings.
Complete. Support for Script (including contained source), field, component, unit, and meta.
Complete. Utility methods getType(fieldName) and getAccessType(fieldName) supporting every field in every node.
Complete. Add 51 conversionFactor convenience constants for unit statement scale factors.

	http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/Core/unitObject.html#CONVERSIONFACTOR_ANGLES_toRadiansFromDegrees
	http://www.web3d.org/x3d/content/examples/X3dSceneAuthoringHints.html#Scale

Example use:
	unitAngle .setName("AngleTest" ).setCategory(unitObject.CATEGORY_ANGLE ).setConversionFactor(unitObject.CONVERSIONFACTOR_ANGLES_toRadiansFromDegrees);
	unitAngle .setName("AngleTest" ).setCategory(unitObject.CATEGORY_ANGLE ).setConversionFactor(unitObject.CONVERSIONFACTOR_DEFAULT_VALUE);
	unitLength.setName("LengthTest").setCategory(unitObject.CATEGORY_LENGTH).setConversionFactor(unitObject.CONVERSIONFACTOR_LENGTH_toMetersFromYards);
	unitLength.setName("LengthTest").setCategory(unitObject.CATEGORY_LENGTH).setConversionFactor(unitObject.CONVERSIONFACTOR_DEFAULT_VALUE);
	head.addUnit(unitAngle);
	head.addUnit(unitLength);

2. Specification issues list for Abstract SAI and Java SAI is pretty stable.

3. Test program and library are getting daily improvements.  These are also in version control so that changes can be tracked - very helpful, especially for sleuthing if something goes sideways.  Source and resultant demo scene online at
