[x3d-public] X3DOM and Three.js

[Leonard Daly]

I would like to have an application that merged X3DOM and Three.js. The 
specific requirements are below. I would like to use this to easily 
handle X3D declarative data and the ability to investigate additional 
capabilities that are included in Three (animation, shaders, rendering, 
VR, etc.). There are also many tools that work in conjunction with Three 
that would be nice to use at various times. I also want to have the DOM 
interaction provided by X3DOM.

There is an X3D loader for Three 
(https://github.com/jonaskello/three-x3d-loader); however, it's node set 
is very limited (e.g., no animation) and it does not appear to provide a 
DOM interface. John Carlson mentioned he had one, but I am not sure if 
it meets the DOM interface requirements. Johannes mentioned that they 
looked into Three as a renderer, but at the time there were too many 
differences between X3D and how Three handled the scene graph and 
rendered the result.

Initial Requirements
1) Use Three.js for all rendering
2) Provides DOM interface to X3D scene
3) Handle most X3D nodes
4) Easy to add new nodes or features (see A-Frame for an example of "easy")

The application needs to be able to run in the DOM and construct a scene 
graph using Three from X3D tags (nodes) in the HTML file. In general all 
tags and attributes (nodes and fields) need to be accessible from DOM 
(both read and write). Internal animations (TimeSensor --> Interpolator 
--> TargetNode) need to work.

So far my preliminary investigation indicates that the problem is 
doable. The difficult part appears to be parsing the nodes In the HTML 
file and keeping the DOM reference from the node to the Three object. I 
have no idea of the performance would be, though it does need to be near 
90 fps (browser willing).

Does anyone have any insights, comments, or thoughts on such an application?
