## 1. Human anatomy 3D mesh data — Z-Anatomy / hpfrei

- **Source models:** Z-Anatomy — <https://www.z-anatomy.com/>
- **Browser-ready model conversion and metadata:** hpfrei/body-anatomy-3d-viewer — <https://github.com/hpfrei/body-anatomy-3d-viewer>
- **Files used:** `assets/models/body.glb`
- **License:** Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0)
- **License text:** `assets/models/LICENSE-CC-BY-SA-4.0.txt`
- **Upstream notice:** `assets/models/LICENSE-Z-ANATOMY-NOTICE.txt`

### Changes made for this project

The model was integrated into a custom educational interface and modified / used as follows:

- Separate anatomical layers for bones, muscles and illustrative viscera.
- Per-mesh picking, hover and selected-state highlighting.
- Region-based camera focus and opacity dimming.
- Replacement of the pelvic region with a separate female hip bone mesh in female mode.
- Custom lighting, background, materials, platform, camera controls and UI.
- Added Chinese anatomical labels, functional descriptions and clinical-learning notes.

The model data and derivative mesh materials distributed here remain available under CC BY-SA 4.0. The site's original code and written content are provided for the user's project; they do not alter the upstream model license.

## 2. Female os coxa — NIH 3D

- **Dataset:** NIH 3D, Entry 15843 — “Female pelvic models” (female os coxa with related pelvic models)
- **Source:** <https://3d.nih.gov/entries/15843>
- **File used:** `assets/models/female-os-coxa.glb`
- **Access:** Public NIH 3D model. Users should consult the NIH 3D Terms and Conditions and the original entry metadata for authoritative terms: <https://3d.nih.gov/terms>
- **Use here:** the left os coxa mesh is loaded at runtime and mirrored to produce a bilateral female pelvis for the educational sex-comparison mode.

Site-specific changes: material replacement, scale/orientation alignment, mirroring, picking metadata and integration with the educational interface.

## 5. Reference video and visual reference images

The file `5a25c021fdc9bc551eee7302d35599da.mp4` was provided by the project owner as a visual/interaction reference for the interface. It is not loaded or redistributed by the website at runtime. The website implements its own educational anatomy interface and does not reuse media from that video.

The superficial-muscle teaching images supplied by the project owner were used only as naming and viewing-order references. The original images are not bundled in the website, and no third-party illustration is redistributed as a website asset.
