[x3d-public] HAnim LOA4 Templates. Choices. Preference?

[Joe D Williams]

How about using that joint centers from that page of hierarchy I sent? 
Please try that.

Those are close to what is in Part 1 Annex A standard.
All loa3 are there but some v2 loa4 joint locations are missing. 
Might try estimating some missing ones.
Joe

Subject: HAnim LOA4 Templates. Choices. Preference?

I’m going to pull HAnim centers from somewhere—not Joe’s hierarchy, but that’s the what I’m basing the skeleton on. The choices 1) X3DUOM. 2) the standard.   3) Katy’s file.  I don’t have any code for 1. My preference is 3, 2, 1.  I think the best long  term is 1.   I’d rather not do schema at this point. 
I will start work on 1 in python and/or JavaScript, working with X3DUOM to extract centers.  My target is either JSON directly from Joe’s hierarchy, which contains places for x y z already, or Katy’s format.  I already have JavaScript code for generating VRML from JSON.  I will use python to dump X3DUOM to Katy’s format, then I’ll use JavaScript to bring that into the JSON.
 
Hopefully, I’ll be able to regenerate Joe’s hierarchy from the JSON with more x y z filled in.   I’m already storing indentation strings.
 
Is there a another source besides Joe’s hierarchy for Joint and Segment id?  I’ll probably carry them forward as comments.
 
I have nascent JavaScript code for “approving” joints, segments and sites.  More on that later.
 
John
