The current WebGL-based implementation (X3DOM.org) is really only an  
experimental solution. It helps to sell our main points to the HTML  
community

- Live X3D scene as part of your DOM which allows you to manipulate  
the 3D content by only adding/ removing or changing DOM elements.
- X3D without any plugin or plugin-interface
- X3D reduced to the max: No PROTO or Scripting on the X3D-scene-side.  
All partitioning and scripting is done on the HTML side.

This intermediate solution has two major drawbacks

- Feature: The current WebGL/Javascrpt layer does not allow advanced  
feature e.g. (spatial) sound or movie textures.
- Performance: WebGL is quite fast but we still have to do all the  
traversals and scene-updates in Javascript.

But the X3DOM architecture is not bound to an WebGL renderer backend.

The next step will be support for existing X3D-SAI browser as  
rendering and animation backbends.
The whole design (not the current impl.) was chosen with different  
backbends in mind.
(http://www.web3d.org/x3d/wiki/images/3/30/X3dom-web3d2009-paper.pdf)

Therefore we believe some single line per (X)HTML document will stay  
for a while:

<script type="text/javascript" src="http://x3dom.org/x3dom/release/x3dom.js 
" />

Future version of X3DOM will use WebGL, X3D-SAI, O3D, or browser  
native implementation
transparent for the app-developer.

The actually backend will be chosen automatically or based on the  
content X3D-Profile.

Therefore the current HTML-X3D solution should not be called "The  
webgl solution".
"X3D in DOM" or short X3DOM makes more sense.

best regards,
johannes
