[x3d-public] Human anatomy model conversion challenge: adapt basic X3D medical models to Humanoid Animation (HAnim) standard

[Don Brutzman]

We have a bunch of high-quality skin and bone models, originally produced
by NIST and available in open-source X3D at

   - X3D Example Archives: Basic, Medical
   - The X3D MedicalInterchange profile is designed for Exchange of
   polygonal geometry, volumetric data and accompanying documentation between
   medical imaging systems. Potential implementation includes
   industry-specific applications that use X3D as an interchange format, but
   link to proprietary databases and hardware.

The structure of these models is pretty simple, but the naming and
organization is all informal and ad hoc, reflecting the state of our
emerging practices 12 years ago.

An excellent opportunity beckons:  add HAnim structures to make these
compatible with much work that continues in the HAnim Working Group.  This
task is essentially the appropriate insertion of HAnimJoint, HAnimSegment
and HAnimHumanoid nodes to organize the skeleton models.

Several tools exist to help with such an endeavor, no doubt several experts
will want to help advise too.  Improvements to diagnostics and best
practices will probably emerge during such an effort.

If anyone is interested in this excellent challenge, let's continue the
discussion on x3d-public and work to collaboratively provide useful
human-skeleton assets for the HAnim working group.  Results, if correct and
valid, will get added to the HAnim model archives and (no doubt) see a lot
of future usage.

   - HumanoidAnimation (HAnim) X3D Examples Archive
   - The HumanoidAnimation (HAnim) X3D Examples Archive includes a growing
   number of humanoid models using joints, segments, skin, and animation
   behaviors.

Thanks for considering the possibilities.  Have fun with X3D and
HAnim!  🧍🩻

all the best, Don
