        In this example, a simple 3D scene is integrated into a web page. This is done by the &lt;X3D&gt; tag in the
        HTML document.
        The &lt;X3D&gt; tag is interpreted by the x3dom.js Java Script library. You can either make a local copy of the
        library or use it
        from the server. It is recommended to use the library from the server to ensure that you always have the latest
        version.
        A local copy of the library is useful for development, if you are not always connected.
        <br>
        <pre class="prettyprint">
	&lt;X3D id="shapedata" width="600px" height="600px" style="float:left"&gt;
	&lt;Scene&gt;
          &lt;background transparency='0' skyColor='1 0 0'&gt; &lt;/background&gt;
            &lt;Shape id=box&gt;
              &lt;Box&gt; &lt;/Box&gt;
            &lt;/Shape&gt;
	  &lt;/Scene&gt;
        &lt;/X3D&gt;
        </pre>
        The &lt;X3D&gt; tag defines the size of the 3D canvas on the web page as well as the scene graph.
        An <a href="http://www.web3d.org/files/specifications/19775-1/V3.3/Part01/concepts.html#scenegraph"
          target="_blank"> X3D scene graph </a>
        is defined as a directed acyclic graph.
        The nodes of the scene graph will be rendered on the screen from a given camera position.
        The default camera position is (0,0,10) pointing to the negative z-Axis.
        So objects at the center of the coordinate system will be displayed on the screen.
        A shape node contains a geometry. In this example, it is a simple box. The center of the box is at (0,0,0) with
        default size 2 in all dimensions
        <br>
        The color of the background can be changed in the attribute skyColor. Currently it is red.
        The color is defined using <a href="http://en.wikipedia.org/wiki/RGB_color_model" target="_blank"> RGB color
          model </a>
        with arithmetic notation (0.0 t0 1.0 per value). <br>
        The color of the Box can be changed by applying an appearance to the shape node.
        In X3D, the <a href="http://www.web3d.org/files/specifications/19775-1/V3.3/index.html" target="_blank"> Shape
          node </a> associates a geometry node with
        nodes that define that geometry's appearance. The following example draws a blue box.
        <pre class="prettyprint">
	&lt;X3D id="shapedata" width="600px" height="600px" style="float:left"&gt;
	&lt;Scene&gt;
          &lt;background transparency='0' skyColor='1 0 0'&gt; &lt;/background&gt;
            &lt;Shape id=box&gt;
              &lt;appearance &gt;
                &lt;material diffuseColor='0 0 1'&gt;&lt;/material&gt;
              &lt;/appearance&gt;
              &lt;Box&gt; &lt;/Box&gt;
