Right, Sandy. Thanks. Great work in compiling that important data.
My big point is that there is a list of 'standard' named feature 
points along with some 'typical' xyz locations given in what I am 
calling skeleton space. The actual xyz location of a feature point can 
be adjusted according to the dimensions of any specific subject human. 
Further, I think that the skin should also be drawn in skeleton space 
and include all feature points as vertices of the skin.
This means we need more specific 'standard' feature points, especially 
for the face, hands, and feet. Then we can provide 'standard' skin(s) 
with 'standard' joint to skin and displacer to skin bindings.

Best Regards,
Joe

Actually the original feature points are based on "anthropometric 
landmarks" that come from the CAESAR project which is in the 
bibliography of the standard: CAESAR—Digitally Defining the Human 
Body, SAE International, 2003.
