[x3d-public] A Layer/Layout yottzumm/coderextreme example scene to talk about

[John Carlson]

I have this JavaScript which used to convert X3D Scripts to HTML scripts
for X3DOM, but since X3DOM does its own Protos now, I haven’t tested it in
a long time.  Someone could pick it up.  Note it works with JSON, not XML.
https://github.com/coderextreme/X3DJSONLD/blob/master/src/main/node/Script.js

I could dual license, it’s all my own code.

So that’s how to make X3DOM work with Script events.  X_ITE doesn’t use
HTML scripts, it has its own.

Enjoy,

John
