## BodyParts3D (geometry, structure names, anatomical hierarchy)

The 3D geometry in `data/hd/glb`, `data/lite/glb`, the piece and structure lists in
`atlas.json`, and the concept hierarchy are derived from **BodyParts3D** release 4.0
(is-a tree, `isa_BP3D_4.0_obj_99`).

Changes made: meshes were welded, re-oriented to glTF conventions (y up), simplified with
meshoptimizer under a 0.2 mm (HD) or 0.6 mm (lite) error bound, and packed into per-system
glTF files with quantised, meshopt-compressed attributes. Pieces were grouped into systems,
organs and regions by rules described in `tools/classify.py` and `content/`.

Release 3.0 tables (`conventional_part_of.txt`, FMA.csv) were used during classification to
derive organ-system membership.

## Foundational Model of Anatomy (names, concept ids)

Structure names and FMA identifiers come from the Foundational Model of Anatomy ontology
(University of Washington), distributed with BodyParts3D.
