# B.2 Feature points

H-Anim feature point names are derived from the 3D Landmarks defined in the CAESAR project (see [CAESAR]) and the body-measurement landmarks in ISO 7250 (see [ISO 7250]), a widely used set of human measurements that are traditional univariate measures, commonly used in anthropometric surveys.

The listed names have been modified to conform with common anatomical spellings and the naming conventions used in the rest of this International Standard.

The feature point names defined here are the basis for names fields used by Displacer and Site nodes. Suffixes (corresponding to purpose) are appended, and optional prefixes (corresponding to Humanoid name) are prepended, as appropriate for each object.

The positions of the H-Anim feature points are indicated using the index values of Table B.2 in the follow-on location diagram Figure B.1.
