[x3d-public] First light...ROUTEs (weights?) into Blender. Animated too! Had to use .wrl. XML does not provide.

Hey, you don't care about the freakin bones.  
If that tool will do bones then it will do joints. 
Bone orientation is same as joint rotation when rigged right. 
Forget bones, the joints are what runs the model and 
when bones are at highest level, then you have to compute joint centers anyway. 
  So, forget bones and just think about joints and the bones will take care of themselves. 
  
All it is is just sets of transforms.  
Hierarchy is Joint, Segment, Site not Bone, whatever.

Using keyframe_insert on the bone seems to be key, and our import code doesn’t use it.  So…

This looks good, but I will have to take the Interpolators apart from the export.

I have not added fields as an attribute to ROUTEs in the XML parser, rather, I deal with from and to fields in routes directly.
 
This code is not all updated (there’s an issue with AnimOb’s created for bones, and bones don’t have an animation_data attribute in python).  That is, I’m trying to import skeleton, and I don’t know how to import animations for skeleton, except through a proxy, creating another level in the animation.

There was different functionality between .wrl and .x3d imports, for example, ROUTEs do not have a “fields” python attribute in some cases with .x3d (look for hasattr…fields under importRoute).
 
I have remedied that.
 
My animations are not perfect yet, still dealing with the flare.
 
There was also something with Interpolators not being read in, but interpolators rely on ROUTEs to reference them, last I checked or remember.
 
I am working with .x3d now.
