[cc: x3d-public, come one come all!]

With completion of the X3D SAI bindings and appendices, am now preparing to re-look at the X3D JSON challenge.

It appears that I can use similar XSLT conversion methods to turn an .x3d file into a .json scene graph. The design pattern appears to be reasonably straightforward.  I hope to be autoconverting a few thousand .x3d scenes shortly thereafter.

Wondering, as that emerges, is there an X3D .json loader that could be written for X3DOM to test it?  Wondering, who is familiar enough with the X3DOM codebase to use or adapt that?

Am happy to work with anyone who wants to pursue this interesting challenge.  It would be great to have progress in motion for the VR Hackathon.  Two weeks away, 17-19 OCT.  Check out the cool new site:

When it is all working, we then expect to write a formal specification document for the encoding to ensure that code and content remains stable.


Having even more fun with X3D + JSON soon, I hope...

all the best, Don
