[Korea-chapter] [h-anim] H-Anim WG meeting, January 27th, 5:30pm PST (28th, 10:30am KST)

Mon Jan 28 07:10:48 PST 2013

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.
