Here are examples that show different ways of combining HTML web pages and X3D scenes.

HelloWorld.x3d standalone scene

HelloWorld.x3d shows a simple standalone example (.html and .png) 

 <?xml version="1.0" encoding="UTF-8"?>
 <!DOCTYPE X3D PUBLIC "ISO//Web3D//DTD X3D 3.2//EN" "http://www.web3d.org/specifications/x3d-3.2.dtd">
 <X3D profile='Immersive' version='3.2' xmlns:xsd='http://www.w3.org/2001/XMLSchema-instance' 
   xsd:noNamespaceSchemaLocation='http://www.web3d.org/specifications/x3d-3.2.xsd'>
   <head>
     <meta name='title' content='HelloWorld.x3d'/>
     <meta name='identifier' content='http://www.web3d.org/x3d/content/examples/HelloWorld.x3d'/> 
   </head>
   <Scene>
     <Group>
       <Viewpoint centerOfRotation='0 -1 0' 
         description='Hello world!' position='0 -1 7'/>
       <Transform rotation='0 1 0 3'>
         <Shape>
           <Sphere/>
           <Appearance>
             <Material diffuseColor='0 0.5 1'/>
             <ImageTexture url='"earth-topo.png"' />
           </Appearance>
         </Shape>
       </Transform>
       <Transform translation='0 -2 0'>
         <Shape>
           <Text solid='false' string='"Hello" "world!"'>
             <FontStyle justify='"MIDDLE" "MIDDLE"'/>
           </Text>
           <Appearance>
             <Material diffuseColor='0.1 0.5 1'/>
           </Appearance>
         </Shape>
       </Transform>
     </Group>
   </Scene>
 </X3D>


X3D embedded in HTML page

HTML Object Tag for X3D shows how to place X3D objects within an HTML page

newHtmlPageWithX3dObject.html is an example HTML scene with X3D object tag to copy, edit and reuse. 

<html>
 <body>
  <object data="http://www.web3d.org/x3d/content/examples/HelloWorld.x3d"
    type="model/x3d+xml" height="360" width="	
    <param name="src" value="http://www.web3d.org/x3d/content/examples/HelloWorld.x3d"/>
    <param name="DASHBOARD" value="FALSE"/>
    <param name="SPLASHSCREEN" value="
    <!-- the following anchor-link text is only displayed to user if no X3D plugin is already installed -->
    <div class="noX3dPluginInstalled">
      <a href="http://www.web3d.org/x3d/content/examples/X3dResources.html#Applications" target="helpPage"> 
      Select an X3D plugin to see this example...</a>
    </div>
  </object>
 </body>
</html>


HTML Anchor link to X3D document

HTML anchor links allow an HTML page to load the contents of an X3D scene.

HTML source: 

      Here is my
      <a href='HelloWorld.x3d' title='Link to a new X3D document'>HelloWorld example</a> in X3D.

HTML result: 

       Here is my HelloWorld example in X3D.

Typically Web browser responses to a user selecting the link:

  • Show X3D scene, if an X3D plugin is installed or native support for X3D is provided
  • If X3D file format is unrecognized, browser might save file or else provide the user a choice to launch an external application (such as an X3D viewer or editor)
  • Show source (if http server X3D MIME type settings are incorrect)


X3D embedded using object element

    <object name='x3dBlock' type='model/x3d+xml' 
      allow-same-origin allow-scripts>
      <param name='src' value='aScene.x3d'>
        <table>...</table>
    </object>
  • Opens nested browsing context in parent block element.
  • Fallback to html. (table in this case.)
  • Connections with DOM via event listeners (DOM<=>SAI).
  • Set of negotiated <param> pairs: initialization and runtime.


X3D served as text/html (no namespace prefix)

      <!DOCTYPE html>
      <html>
        <head>
          <style type=text/css'>
            X3D { height:100%;width:100%; }
            svg { height:100%;width:100%; }
          </style>
        </head>
        <body>
          <X3D name='x3dBlock' type='model/x3d+xml' 
            version='3.3' profile='Interchange'
            allow-same-origin allow-scripts>
            <Scene>
              <Viewpoint description='Start' />
              <Shape>
                <Box size="4 4 4" />
              </Shape>
              <Shape>
                <Text string='"This is X3D Text"' />
              </Shape>
            </Scene>
          </X3D>
          <svg type='image/svg+xml' version="1.1">
            <ellipse cx="2cm" cy="4cm" rx="2cm" ry="1cm" />
          </svg>
          <mathml>
            <mrow><mi> x </mi><mo> + </mo>
            <mrow><mi> a </mi><mo> / </mo><mi> b </mi>
            </mrow></mrow>
          </mathml>
          <ruby> WWW <rt>World Wide Web</rt>
          </ruby>
        </body>
      </html>

X3D served as application/xhtml+xml (with namespace prefix)

      <?xml version="1.0" encoding="utf-8" ?>
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml">
        <head>
          <style type=text/css'>
            x3d:X3D { height:200px;width:200px; }
          </style>
        </head>
        <body>
          <x3d:X3D name='x3dBlock'
            xmlns:x3d=
            "http://www.web3d.org/specifications/x3d-3.2.xsd">
            <Scene>
              <Shape>
                <Box size="4 4 4" />
              </Shape>
              <Shape>
                <Text string='"This is X3D Text"' />
              </Shape>
          </Scene>
        </x3d:X3D>
      </body>
      </html>

X3D served as application/xhtml+xml : HTML onClick() Event

[note: Box is not allowed to have an onclick attribute, needs to be fixed] 

      <?xml version="1.0" encoding="utf-8" ?>
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml">
        <head>
          <style type=text/css'>
            x3d:X3D { height:200px;width:200px; }
          </style>
        </head>
        <body>
          <x3d:X3D name='x3dBlock' xmlns:x3d="http://www.web3d.org/specifications/x3d-3.2.xsd">
            <Scene>
              <Shape>
                <Box size="4 4 4" onclick="alert('box picked at position ' + hitPnt);"  />
              </Shape>
              <Shape>
                <Text string='"This is X3D Text"' />
              </Shape>
          </Scene>
        </x3d:X3D>
      </body>
      </html>

X3D served as application/xhtml+xml : updates on the tree

      <?xml version="1.0" encoding="utf-8" ?>
      <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" 
        "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
      <html xmlns="http://www.w3.org/1999/xhtml">
        <head>
          <style type=text/css'>

          </style>
        </head>
        <body>
          <x3d:X3D name='x3dBlock'
            xmlns:x3d=

            <Scene>
              <Shape>
                <Appearance>
                  <Material diffuseColor="1 0 0"  />
                </Appearance>
                <Box size="4 4 4" />
              </Shape>
              <Shape>
                <Text string='"This is X3D Text"' />
              </Shape>

           return false;
