Of course the main idea here is that we build the realistic h-anim
character example skeleton in 'human' space with 'human' dimensions.
Thus the specification example typical locations of joints and feature
points are given in the coordinate system of a typical human, starting
from the floor where it stands, with xyz = 0,0,0 at about the center
of the body left/right/front/back, at the standing surface between the
feet, with +x to the left, +y up, and facing +z , extending to the top
of the skull.
All the Best,
Joe

Changed title to focus comments on surface feature points used for
Skin Drawn in Skeleton Space with Joint Bindings.
Just to pin down what I am discussing as the "skin drawn in skeleton
space" please see this part of listing from:

# h-anim2: we need to know the exact order in which

So, I approximated some and gave simple offsets for convenience
hooking up others. Not all surface feature points of interest in
scanning, motion capture, animation, recognition, simulation
applications are included. We need various 'standard' levels of
density and grouping for various areas. Lots of research to find, then
work with care to hook them up.
Document best practices for competent 'standard' skin(s) with
'standard' skin vertex to joint and displacer bindings.
Thanks and 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.
