Thanks John, this is the most complete freestanding list outside the spec I know of. 
When you see x y z it means there is no published dimension for that joint or site.

I found a small issue with the r_clavicale, I think. New version attached.

Here are some feature points we don't have a location for, from Joe's list. Anyone want to try for locations?
 
I found these in the standards stuff I had table A.11.  I guess Joe didn't think they were good for his hierarchy (attached with new values plugged in).
 
      <td><span class="Code">l_metacarpal_phalanx_2</span></td>
      <td><span class="Code">r_tarsal_distal_phalanx_1_tip</span></td>
      <td><span class="Code">spine_2_lower_back</span></td>
      <td><span class="Code">supramenton</span></td>

 
Thanks!

Here is the attachment on the first 11 feature points.  The site for the translations do not have points numbered so I added in that column.  As you can see from this attachment - the feature points are independent of the joints as it does not matter which LOA that you choose. 
 
But questions - during the animation - do the feature points move?  How are they bound to the mesh and skin?  If the skin (mesh) breaks during a movement - what happens to the feature point? 
 
Thanks

I have been looking into this.  And I am agreeing with John's assessment. I will somehow need to get everything into Rhino for visualization and coding. 
 
>From John on March 14th. 
I am thinking that humanoid_root and all other joint centers are relative to the LCS (local coordinate system) of the humanoid, which is 0, 0, 0 relative to any transforms outside the humanoid.
That's my best guess right now.
 



What is not noted on the General is the exact file or model for which these translations were built for.  This means that the list of the translations on the website only valid for the humanoid model that they were obtained for, the distance of that model from the origin and are not appropriate for Gramps or any other model. 
 
This means that for every joint center and every translation, it would be good to have reason for why is it located where it is.

Is this the model for which the translations are built for?  Can someone send me the proper link? Is this it?  I will see if I can import it into Rhino 8. 
HumanoidAnimation/Skin/Joe*.x3d 
 
Back to updating every 120 points currently listed as to recommendations of how to locate it and adding the additional feature points that I have requested.

Great John,
I will check this out soon. 
Any ideas for the 'virtual' feature points? 
All Fine, 
Joe

 
Joe, do you mean user drawn, not in current standard? User defined points?  I have scripts for sites to place coordinates, but I don't have  a way to get them into the hierarchy yet, so...
 
John

Carol, I'm discovering it makes a difference where you put the Transform in the HAnimSegment as to whether to reuse the center.  I don't have something that doesn't put out warnings yet, or takes the Sites away from the Joints.  Hmm! 
My best Humanoid so far is Humanoid4J.x3d.
 
I'm going to get some sleep.

Good use of Billboard for annotated feature points 
Please consider this a contribution to the Web3DConsortium examples.  I release my copyright and licensing privileges, and give them copyright and licensing under the normal X3D resources example.
 
Thanks to Joe and Don for good examples to draw from!
 
No, I don't have any metadata yet.  Let's set up a time and figure out who all contributed.
 
You can make the skin opaque to see that I'm really grabbing this from a HumanoidAnimation/Skin/Joe*.x3d example, just my own incantation of scripts to draw the humanoid geometry.  I'll be checking those in soon.
