Subject: Re: [x3d-public] announce: X3D Java Scene Authoring Interface<br>
(SAI) open source, beta supports colors and field names for ROUTEs<br>
Message-ID: <<a href="mailto:ef017f6d-1a6c-50e3-28dd-ddc3d62cafa3@nps.edu" target="_blank">ef017f6d-1a6c-50e3-28dd-ddc3d<wbr>62cafa3@nps.edu</a>><br>

<br>
Two nice programming features have emerged during beta-test development.<br>
<br>
X3D Java Scene Access Interface (SAI) Library<br>
<a href="http://www.web3d.org/specifications/java/X3dJavaSceneAuthoringInterface.html" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/X3dJavaSceneAuthori<wbr>ngInterface.html</a><br>
<br>
1. /Complete/. Added support for numerous hexadecimal 0xRRGGBB integer colors (through defined constants and utility methods) to SFColorObject and related classes.<br>
<br>
Reference:<br>
CSS Color Module Level 3, 4.3. Extended color keywords<br>
<a href="https://www.w3.org/TR/css3-color/#svg-color" rel="noreferrer" target="_blank">https://www.w3.org/TR/css3-col<wbr>or/#svg-color</a><br>
<br>
147 Web colors provided as Java SFColor RGB values:<br>
<a href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/fields/SFColorObject.html" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/javadoc/org/web3d/<wbr>x3d/java/fields/SFColorObject.<wbr>html</a><br>
<a href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/fields/SFColorObject.html#ALICEBLUE" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/javadoc/org/web3d/<wbr>x3d/java/fields/SFColorObject.<wbr>html#ALICEBLUE</a><br>
<br>
Example source showing use:<br>
<br>
boxMaterial.setDiffuseColor(Ma<wbr>terialObject.DIFFUSECOLOR_DEFA<wbr>ULT_VALUE);<br>
boxMaterial.setDiffuseColor(ne<wbr>w float[] {0, 1, 1}); // equivalent<br>
boxMaterial.setDiffuseColor((n<wbr>ew SFColorObject(0.0f, 1.0f, 1.0f)).toFloatArray()); // equivalent<br>
boxMaterial.setDiffuseColor((n<wbr>ew SFColorObject(0x00FFFF)).toFlo<wbr>atArray()); // equivalent<br>
boxMaterial.setDiffuseColor(SF<wbr>ColorObject.CYAN); // equivalent<br>
<br>
<br>
2. /Complete/. Add string constants naming each field eligible for ROUTE connections,<br>
e.g. OrientationInterpolatorObject.<wbr>toField_SET_FRACTION and<br>
<wbr>OrientationInterpolatorObject.<wbr>fromField_VALUE_CHANGED.<br>
<br>
Example source showing use:<br>
<br>
ROUTEObject spinROUTE = new ROUTEObject();<br>
spinROUTE.setFromNode(clockDEF<wbr>).setFromField("fraction_<wbr>changed")<br>
.setToNode(orientationInterpo<wbr>latorDEF).setToField("set_<wbr>fraction"); // equivalent, typos possible<br>
<br>
spinROUTE.setFromNode(clockDEF<wbr>)<br>
.setFromField(TimeSensorObjec<wbr>t.fromField_FRACTION_CHANGED)<br>
.setToNode(orientationInterpo<wbr>latorDEF)<br>
.setToField(OrientationInterp<wbr>olatorObject.toField_SET_<wbr>FRACTION); // equivalent, correctly named<br>
<br>
<a href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/Interpolation/OrientationInterpolatorObject.html#toField_SET_FRACTION" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/javadoc/org/web3d/<wbr>x3d/java/Interpolation/Orienta<wbr>tionInterpolatorObject.html#<wbr>toField_SET_FRACTION</a><br>
<a href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/java/Interpolation/OrientationInterpolatorObject.html#fromField_VALUE_CHANGED" rel="noreferrer" target="_blank">http://www.web3d.org/specifica<wbr>tions/java/javadoc/org/web3d/<wbr>x3d/java/Interpolation/Orienta<wbr>tionInterpolatorObject.html#<wbr>fromField_VALUE_CHANGED</a><br>
<br>
As with other Java constructs, these field names get automatically generated into the Java SAI Library by using information found the X3D Object Model. So these string constants are always correct and always available to the programmer. It is always valuable to try pushing error detection from end-user run time (ouch) to programmer compile time (aha, a bug to fix). These good programming practices add up, and all help X3D Quality Assurance (QA).<br>

3. Test program and library are getting daily improvements. Source and resultant demo scene online at<br>
