Anatria3D — anatomical mesh assets ================================== The 3D meshes and anatomical nomenclature in this directory are NOT covered by the Anatria3D application licence. They come from open anatomical datasets and keep the terms their authors set. **There are two atlases here, from two unrelated sources, under two different licences.** See the LICENSE file alongside this one for which files are which. The short version: `*_male.glb` and `manifest.json` are CC BY-SA 4.0; `*_female.glb` and `manifest_female.json` are CC BY 4.0. THE MALE ATLAS — CC BY-SA 4.0 ============================= Attribution chain ----------------- 1. BodyParts3D The Database Center for Life Science (DBCLS), Japan Licensed under Creative Commons Attribution-ShareAlike 2.1 Japan https://creativecommons.org/licenses/by-sa/2.1/jp/ 2.

Licensed under Creative Commons Attribution-ShareAlike 4.0 International https://creativecommons.org/licenses/by-sa/4.0/ https://www.z-anatomy.com/ 3. Anatria3D adaptations The .glb files here are adaptations of the Z-Anatomy meshes, produced by a headless Blender export (tools/asset-pipeline/): conversion from .blend to glTF binary, Blender modifiers baked into the exported geometry, lossy Draco compression (position quantisation 14 bits, normal 10), materials dropped in favour of shading applied by the viewer, and the addition of stable organ identifiers. The anatomical hierarchy in manifest.json is derived from Z-Anatomy's own collection nesting. No polygon reduction is applied beyond what Draco quantisation implies. Anatomical labels are taken from Z-Anatomy's TA2.csv (Terminologia Anatomica 2). That file is shipped unmodified, and it is not a clean copy of the standard: an audit of every label found 61 terms misspelled, truncated, or naming a structure other than the English beside them — `Truncus coeiiacus` for *coeliacus*, `Venae pudendales extemae` for *externae*, `Arteria pancreaticoduodenalis` for the *inferior* one, and fifty rows that had taken the French spelling from the neighbouring column. All are corrected as the file is read, never in the file itself, so the vendored standard stays byte-identical to upstream and the corrections stay reviewable. Every correction is listed with its evidence in `tools/asset-pipeline/ta2.mjs`, and the build fails if one of them stops matching a row. Corrections to rows that the vendored file adds *past the end of the standard* are kept in a separate table, because those are our own compositions rather than restorations of anything TA2 published. These corrections apply to both atlases: the female one joins the same file. As adaptations of CC BY-SA 4.0 material, these files are themselves licensed under Creative Commons Attribution-ShareAlike 4.0 International: https://creativecommons.org/licenses/by-sa/4.0/ What this means in practice --------------------------- - These asset files may be redistributed, including commercially, provided the attribution above is preserved and they remain under CC BY-SA 4.0. - The share-alike obligation attaches to the meshes and their derived label data. It does not extend to the Anatria3D application source code, which merely aggregates these assets rather than adapting them. - Do not relicense, or claim exclusive rights over, anything in this directory. THE FEMALE ATLAS — CC BY 4.0 ============================ `*_female.glb` and `manifest_female.json` are the trunk — spine, abdominal organs, pelvis and breast. They are not a female whole body, and no open dataset provides one. Attribution chain ----------------- 1. Visible Human Female U.S. National Library of Medicine, National Institutes of Health.

Anatria3D adaptations Produced by `tools/asset-pipeline/extract-hra.mjs`, entirely inside glTF — no Blender round trip, so the node names are byte-identical to the published digital object and any structure here can be checked against the HRA portal. The changes are: selection of 264 of the 888 structures, the node hierarchy flattened with transforms baked in, source materials and UV sets dropped in favour of shading applied by the viewer, lossy Draco compression (position quantisation 14 bits, normal 10), and stable organ identifiers added. No polygon reduction beyond what Draco quantisation implies. As adaptations of CC BY 4.0 material these files remain CC BY 4.0. There is no share-alike obligation on them, and none is imposed here. Nomenclature, and where it differs from the source --------------------------------------------------- The HRA labels structures with UBERON and FMA terms, which is right for its purpose — mapping cell types — and wrong for teaching: the labels are not unique (six pelvic meshes are labelled "compact bone tissue", naming the tissue rather than the bone), and they word many structures differently from Terminologia Anatomica. So each structure was matched by hand to a TA2 term, recorded in `tools/asset-pipeline/hra-selection.mjs`, and the build fails if any term is absent from TA2. Eleven structures present in the source are deliberately not shipped, because TA2 does not list them and inventing Latin for them would be worse than omitting them. Three more that TA2 *does* name are left out by judgement — the placenta's umbilical vessels, which alone would be a placenta made of three tubes — and those are recorded in a separate list, so a decision cannot borrow the standard's authority. The reasons for all fourteen are in that same file. Where the source and this atlas disagree, the reason is written down rather than applied silently — including one upstream mesh whose label and ontology id belong to a different vessel from the one its node names. Provenance for every shipped structure — original node name, UBERON or FMA id, source label, polygon count — is committed in `tools/asset-pipeline/vendor/reports-female/`. What this means in practice --------------------------- - These files may be redistributed, including commercially, provided the attribution above is preserved. - They may be modified and the result kept closed. CC BY does not require otherwise. This is a real difference from the male atlas. - **Do not merge them with the male meshes or manifests.** Combining CC BY material into a CC BY-SA work forces share-alike onto it, which is a condition the HRA's authors did not choose to impose. Nomenclature, and why nothing here is translated ------------------------------------------------ manifest.json carries two names per structure and no others: the Terminologia Anatomica 2 Latin term, and the clinical English term. There are no localised labels in this data and no machine translation of any kind. That is deliberate. Rendering "Ventriculus sinister" for a layperson, a student and a clinician calls for three different explanations, in each of the languages the application supports — that is teaching, not a lookup table. It is done at runtime by the AI assistant, with the reader's profile and language in hand, and no such text is stored or redistributed here. Redistributing this directory therefore redistributes professional nomenclature only. If you add localised medical terminology to it, that terminology is yours: have it reviewed by someone qualified before presenting it as authoritative.
