Published version that is likely origin of Yvonne's work is

http://X3dGraphics.com/examples/X3dForWebAuthors/Chapter07-EventAnimationInterpolation/

	Dolphin/DolphinMorpher.x3d
	DolphinMorpher.xhtml (X3DOM)
	DolphinMorpher.html  (documentation)
	DolphinMorpher.json

Incidentally we were never able to find the author of the original Maya model.  We found this in the original VRML Proto Repository.  If anyone knows of the provenance please advise, we hope to give credit someday.

The stylesheets won't work on alllowercase elementnames in X3DOM HTML, only valid CamelCaseNames.

It is my understanding that Yvonne took the animated porpoise and converted from .x3d to .json using Don's stylesheet. Then wrote the code that imported the .json file into X3DOM.

A very public use license will allow others to take what you have done and incorporate it into anything and resell it. If you are not careful with the name, your name could be co-opted too. If you want contributions to remain as open-source, than a GPL-type license might be the right choice. Wikipedia has a good starting page on software licenses: http://en.wikipedia.org/wiki/Software_license (Free license comparisons: http://en.wikipedia.org/wiki/Comparison_of_free_and_open-source_software_licenses). Until you figure it out, I recommend that you be restrictive and only let people use it exactly as is (since you already put it out for public use).

There is a Java file to converted XML to JSON (fairly generic), and then a Node.js app to convert the JSON to JavaScript.  This should work in chrome.  I am looking to extend it to other browsers if possible. Comments and contributions are welcome.   If possible, someone could create an XSLT stylesheet to do something similar based on my example.  See attached.   Also let me know what kind of license I should use.

all the best, Don
