[x3d-public] X3D Scripting for X3DOM w/o reading standard

[Joseph D Williams]

➢ 2.  What are the stumbling blocks to getting script fields into the event model?

Hi John,
Scripts are completely involved in the x3d sai event model. A script must receive an event to begin execution and then it is like an ’external’ in that when the script begins it essentially acts like a beginUpdate and when it completes it essentially gets an endUpdate and all outputs are sent with the same time stamp as kicked off the script. Think of it as script is like any other node that can receive and send events. Only exception is, I think, that a script directOut does not initiate a new cascade

➢ 3.  If scripts are transformed, how?

If it is ECMAScript then what do you do? What can be done? Break it down into json like any other node? For some reason I hope not.

Information needed:


1.   Do scripts in proto bodies get copied?

2.  What are the stumbling blocks to getting script fields into the event model?

3.  If scripts are transformed, how?

4.  What is the new event model for X3D4?

John
