The diffuse color of a material will be interactively changed.
A JavaScript <a href="http://jqueryui.com/slider/#colorpicker target=" _blank"> RGB color picker </a> is used
and modified.
If the RGB color value is changed, the diffuse material of the sphere shall be changed as well. So we need to
get the Material node first.
This is done by the getElementById function in X3DOM. Of course, the Material node needs to have an unique id.
<pre>
&lt;X3D id="shapedata" width="600px" height="600px" style="float:left"&gt;
&lt;Scene&gt;
&lt;Shape&gt;
&lt;Appearance&gt;
&lt;Material id="material" diffuseColor="0.980, 0.502, 0.447"&gt; &lt;/Material&gt;
&lt;/Appearance&gt;
&lt;Sphere radius="2.0"&gt; &lt;/Sphere&gt;
&lt;/Shape&gt;
&lt;/Scene&gt;
&lt;/X3D&gt;
</pre>
<br>
For example, if the diffuse color should be set to red, the Material node is referenced by its id and the
attribute diffuseColor is set to
"1.0 0.0 0.0". The attribute value is always a string.
<pre>
var mat = document.getElementById("material");
mat.setAttribute("diffuseColor", "1.0 0.0 0.0");
</pre>
In the example, the RGB value is fetched from the slider.
<pre>
var mat = document.getElementById("material");
rgbstring = " "+ red + " " + green + " " + blue;
mat.setAttribute("diffuseColor", rgbstring);
