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!!

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>
