[X3D-Ecosystem] RawKee Update - Implemented a companion export script for x3d.py

[John Carlson]

   1. JSON export was completely broken.

I tried fixing this in x3d.py and failed.  I have worked on python
validators for JSON export, but it’s slow in Python.  Validating the
scenegraph isn’t enough.

   1. The skeleton and joint export order of the HAnimHumanoid node fields
   using x3d.py would theoretically dump all the DEF’d joints into the
   ‘joints’ field, and thus only produce one USE’d root joint in the 'skeleton
   field. Though I haven’t implemented HAnimHumanoid yet, I re-ordered the
   field export so that the ‘skeleton’ field will get writen to the file
   before the ‘joints’ field.

You’ll also want to verify skin and skinCoord field order, plus sites and
segments field order with skeleton.

   1. ‘containerField’ was not implemented for XML export, which caused the
   textures to not work because they weren’t allocated to the proper texture
   field within the Material node.

Andreas has a good patch for that.

   1. The ‘mapping’ field was missing from the TextureTransform object, so
   it wouldn’t export.


Good catch.

Also,  how did you solve the DEF/USE ordering issue?

I’ll post what i have for JSON elsewhere.

John
I will do a bit of a search for validation.
