## Terminology

- Terminologia Anatomica, 2nd ed. (TA2), FIPAT, via Z-Anatomy `TA2.csv` — TA2 ids (`taId`) and Latin names where the Z-Anatomy `Translations` table has none (unique English matches only).

## Modifications

The Z-Anatomy Blender file (`Startup.blend`) was converted by the learnanatomy.org asset pipeline (`pipeline/`):

- geometry evaluated with all modifiers and curve bevels; subdivision surface capped at level 1, curve resolution capped at 6 and round-bevel resolution at 2
- world transforms baked per object; mirrored left/right instances baked with flipped triangle winding
- converted to metres, Y-up (+Y superior, +Z anterior, +X patient's left), feet at y = 0, z centred; true scale
- simplified with meshoptimizer (absolute error ≤ 0.05 mm, borders locked), quantized (16-bit positions) and compressed with EXT_meshopt_compression
- one material colour per structure (base colour only, no textures); one GLB file per body system
- names (English, Latin, French, Spanish, Portuguese) taken from the `Translations` table, definitions from the text datablocks (title line and trailing source URL separated; marked as not reviewed)
- left/right naming errors corrected after human review (`pipeline/config/overrides.json`):
  - `Eyelashes.l` → right (named left upstream)

## Definitions

Definitions are excerpts from Wikipedia (CC BY-SA 3.0) as included in Z-Anatomy; every definition links its source page. They are shown as "not reviewed" until a human reviewer has checked them.

## Non-commercial content

The following structures come from upstream components under **non-commercial** licences. They are marked `nonCommercial: true` in the data; a commercial deployment must remove them (filter `!s.nonCommercial`).

## Provenance not recorded per structure

Upstream also credits "Brainder" and "White matter" (University of Washington, no licence stated) and "Cranial Nerves and Foramina" (University of Dundee, CAHID, CC BY 4.0) as references/adapted models. The Z-Anatomy file does not record which structures derive from them, so they are credited here as a whole.
