Provider notices: https://github.com/yamz8/human-body-simulator/blob/main/public/THIRD_PARTY_NOTICES.md

Provider changes: Draco optimization and level-of-detail preparation; semantic FMA node grouping; coordinate registration.
BodyBloom changes: illustrative runtime material colors and transparency, a common centering translation, selection highlighting and visibility/isolation. No per-organ geometry relocation. Model binaries are redistributed unchanged from the provider. These assets and model adaptations remain CC BY-SA 2.1 Japan; preserve attribution and license notices on redistribution. This notice does not relicense unrelated original application code.

The brain meshes contain cerebellum/brainstem components only. This is a selected-organ reference, not a complete atlas or a diagnostic model.

## Nervous-system subset (1.2.0)

Required attributions:

- "BodyParts3D - The Database Center for Life Science - CC-BY-SA 2.1 Japan"
- "Z-Anatomy - The open source atlas of anatomy - CC-BY-SA 4.0"

`anatomy-nerves.glb` is a selected derivative from https://github.com/nqwrc/3d-anatomy/blob/master/public/models/nervous.glb, originally exported from Z-Anatomy (https://www.z-anatomy.com/), derived from BodyParts3D (https://lifesciencedb.jp/bp3d/). This selected derivative is CC BY-SA 4.0: https://creativecommons.org/licenses/by-sa/4.0/legalcode. BodyParts3D attribution and upstream notices are retained. See `Z-Anatomy-License.txt`, `Z-Anatomy-upstream-NOTICE.txt`, and `nervous-provenance.json` for the exact 118 retained components and integrity hashes.

The upstream collection as a whole includes restricted/unclear additional assets. The distributed derivative contains ONLY a named whitelist of peripheral nerve/plexus and spinal gray-matter components. All other geometry, including inner ear, cerebral models, and white matter, is physically removed and unreferenced meshes are pruned before export. No upstream text definitions are redistributed. The original three BodyParts3D brain-region meshes remain separate under their existing license.

Changes: world transforms preserved while flattening hierarchy; excluded components removed; geometry pruned and Draco compressed; one uniform scale and translation registers the whole nerve subset to the existing model using the same pons landmark (FMA67943). Landmark scale agreement is recorded per axis. No individual nerve is moved to create a decorative path. Gold colors, ghosted surrounding anatomy, transient highlight pulse and optional camera rotation are presentation choices, not physiological simulation. Reference registration remains subject to independent clinical review.

Redistributions of this nervous geometry, adaptations, or derived renderings must retain the above two attribution strings and share-alike terms. Unrelated application code is not relicensed.

## Bone, muscle, and lymphatic layers (1.3.0)

Required attributions remain:

- "BodyParts3D - The Database Center for Life Science - CC-BY-SA 2.1 Japan"
- "Z-Anatomy - The open source atlas of anatomy - CC-BY-SA 4.0"

`anatomy-skeletal.glb`, `anatomy-muscular.glb`, and `anatomy-lymphatic.glb` are selected derivatives of the corresponding `skeletal.glb`, `muscular.glb`, and `lymphatic.glb` from https://github.com/nqwrc/3d-anatomy/tree/master/public/models. Upstream origins: Z-Anatomy (https://www.z-anatomy.com/), derived from BodyParts3D (https://lifesciencedb.jp/bp3d/). These geometry derivatives and adaptations are redistributed under CC BY-SA 4.0: https://creativecommons.org/licenses/by-sa/4.0/legalcode. Retain both attribution strings, source links, change notices, and share-alike terms in redistributions and renderings. Upstream notices are retained in this directory.

Changes: retain only meshes with matching upstream system metadata; preserve world transforms while flattening hierarchy; omit covering fascia, aponeuroses, tendons, retinacula, sheaths, and intermuscular septa from the muscle view; prune excluded meshes; Draco-compress; apply the same uniform pons-based registration used for the nervous layer. No individual bone, muscle, or lymphatic structure is repositioned. Restricted/unclear source components (inner ear, cerebral and white-matter models, and kidney) are not included; no upstream definitions are redistributed.

`skeletal-provenance.json`, `muscular-provenance.json`, and `lymphatic-provenance.json` contain source/output hashes, exact retained structure names, exclusions, and the common registration. Regenerate with `scripts/prepare-body-layers.mjs` using the external upstream files. The 277 skeletal, 558 muscle, and 158 lymphatic components are partial reference anatomy. Ivory/terracotta/green highlighting, ghosting, and camera motion are presentation choices, not diagnoses or physiological simulations. Independent clinical validation remains pending.

## Reproductive reference subset (1.4.0)

`anatomy-reproductive.glb` contains only 12 explicitly whitelisted male reproductive components from the upstream Z-Anatomy `visceral.glb`: https://github.com/nqwrc/3d-anatomy/blob/master/public/models/visceral.glb . The derivative is CC BY-SA 4.0, with the same required BodyParts3D/Z-Anatomy attribution strings, source links, and notices above. See `reproductive-provenance.json` for exact names, source/output hashes, and registration. All unrelated geometry, including the noncommercial kidney, is physically excluded and pruned. No upstream definitions are redistributed. World transforms are retained with the same uniform registration used for the other Z-Anatomy layers. Purple material and camera focus are presentation adaptations. That male GLB contains no female anatomy; a separate female reference was added in release 1.8.0 (below). No claim of complete coverage or clinical validation is made.

The combined musculoskeletal view reuses the licensed bone and muscle geometry without relocation; muscle translucency exposes the reference skeleton. The integumentary view reuses the existing BodyParts3D skin/body-surface model under its CC BY-SA 2.1 Japan terms. Neither view adds microscopic skin layers or a complete set of connective tissues.

## Female reproductive reference subset (1.8.0)

`anatomy-reproductive-female.glb` is adapted from Kristen Browne and Heidi Schlehlein, **3D Reference Organ Set for Female, v1.5** (2023), Human Reference Atlas / HuBMAP, based on the National Library of Medicine Visible Human Female.

License: **Creative Commons Attribution 4.0 International (CC BY 4.0)**, https://creativecommons.org/licenses/by/4.0/ ; local legal code: `/licenses/CC-BY-4.0.txt`. These female model assets and adaptations are excluded from the proprietary original-UI copyright notice. They remain CC BY 4.0, independently of the separate male Z-Anatomy/BodyParts3D files and their share-alike terms. No endorsement by the source authors is implied.

Changes: selected 22 reproductive meshes and 14 pelvic-bone context meshes; pruned every other component, including pregnancy/placental meshes, other organs, skin and vessels; retained source mesh names, source identifiers, geometry and world relationships; applied a single uniform display scale and translation to the whole subset; Draco-compressed the result; viewer applies illustrative rose and faded neutral materials. No per-organ displacement, morphing, or registration to the male atlas was performed. The two references are displayed separately. Exact retained names, source/output hashes and transform are in `female-reproductive-provenance.json`. The full 201 MB source is not redistributed.

Coverage is partial: uterus/cervix regions, vagina, ovaries, and uterine-tube portions. No external genitalia, mammary anatomy, ligaments, or pregnancy structures are included. No claim of clinical validation or representation of every anatomical variation is made.
