Excuse me but there are some 3D parts in my web pages!!!
Web Browser as Universal Publishing Medium
- Giving out an URL is the best way to distribute content
- Success of the Web proves this
- 3D Content now supported NATIVELY by web browsers
- No Plugins!!
What's In it for the Model Based Enterprise
Annotated Part Example
(thanks Bob Lipman!)

NIST X3DOM Annotation Example
Delarative means simple editing
<shape> <shape onclick="alert('I am a T for Tired Datum');">
Declarative 3D in Web Pages
- DOM - Document Object Model; contains graphic elements
- Manipulating the DOM means you are manipulating graphical elements
- Selecting elements of the DOM means you are selecting those elements of the page you wish to manipulate.
- Of course having multi-Gb mesh type data directly in the DOM is an issue..being dealt with by a variety of compression techniques
Making Geometry Interactive
A Simple Example
<X3D xmlns="http://www.x3dom.org/x3dom"> <scene> <viewpoint position='0 0 10' ></viewpoint> <transform id="exTrans"> <shape> <appearance> <material id="mat" diffuseColor='0.603 0.894 0.909' ></material> </appearance> <box id='box' ></box> </shape> </transform> </scene> </X3D>
DOM Event Example
Inside a <box> element define an "onclick" attribute
<box > </box>
onclick = "alert('you hit the box');"
$('#dialog').html('You hit me');
jQuery UI Demos
WebGL for Universal 3D Content
What is the Web3D Consortium
Open Standards, Open Software
Simply put: it's X3D in your web page
So what is X3D?
An ISO Standard ... ISO/IEC 19775
A REAL STANDARD...not some pseudo standard wannabe!!
X3DOM is a 3D Declarative Markup Lanaguage (for X3D)
it puts X3D in your browser
- HTML/CSS slideshow software (reveal.js):Hakim El Hattab
- code highlighting - highlight.js by softwaremaniacs.org highlight.js.
- slide/web page embedding - lightview.js, Nick Stakenburg, lightview.js
