-        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.

-        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.
