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

==  HTML Anchor link to X3D document ==

      In this case the host browser uses whatever it has access to in order to create a new window browsing context for the target .x3d resource.

* Joe - draft Example #2, embedd using object element.
+
HTML anchor links allow an HTML page to load the contents of an X3D scene.
  
−
    <object name='x3d' type='model/x3d+xml' allow-same-origin allow-scripts>
+
HTML source:
−
          <param name='src' value='aScene.x3d'>
+
−
        <ztable>...</table>
+
−
      </object>
+
−
      Opens nested browsing context in parent block element.
+
−
      Fallback to html table. (s z is artifact).
+
−
      Connections with DOM via event listeners (DOM<=>SAI).
+
−
      Set of negotiated <param> pairs: initialization and runtime.

* Joe - draft Example #3, served as application/xhtml+xml

      Here is my

      &lt;a href='[http://www.web3d.org/x3d/content/examples/HelloWorld.x3d HelloWorld.x3d]' title='Link to a new X3D document'>HelloWorld example&lt;/a> in X3D.
  
−

HTML result:

Typically Web browser responses to a user selecting the link:
−
           <style type=text/css'>
+
* 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 [http://www.web3d.org/x3d/learn/mimetypes X3D MIME type settings] are incorrect)
 +
 
 +
== X3D embedded using HTML5 object element ==
 +
September 2022 status: There are no publicly distributed plug-ins for current web browsers that display X3D content
 +
referenced in an object tag. Current  practice is to render X3D on a web page using a javascript library such as [https://xwdom.org X3DOM] or [https://github.com/create3000/x_ite X_ITE]
 +
 
 +
 
 +
    &lt;object name='x3dBlock' type='model/x3d+xml' allow-same-origin allow-scripts>
 +
       &lt;param name='src' value='aScene.x3d'>
 +
        &lt;-- fallback HTML here -->
 +
    &lt;/object>
 +
 
 +
* Goal for this example is to show some HTML5-specific attributes

* Opens nested browsing context in parent block element

* Set of negotiated <param> pairs for initialization and runtime

Here are several 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'

   </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>

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 HTML5 object element

September 2022 status: There are no publicly distributed plug-ins for current web browsers that display X3D content referenced in an object tag. Current practice is to render X3D on a web page using a javascript library such as X3DOM or X_ITE 


    <object name='x3dBlock' type='model/x3d+xml' allow-same-origin allow-scripts>
      <param name='src' value='aScene.x3d'>
        <-- fallback HTML here -->
    </object>
  • Goal for this example is to show some HTML5-specific attributes
  • Opens nested browsing context in parent block element
  • Set of negotiated <param> pairs for 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%; }

            <Scene>

              <Shape>
                <Text string='"This is X3D Text"' />
              </Shape>
            </Scene>
          </X3D>
          <svg type='image/svg+xml' version="1.1">

          <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"

          <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>
