# Organ-browser thumbnails

Rendered from the existing BodyParts3D male model and the application's tissue presentation. Original scene geometry, source identities and anatomical forms are unchanged. These are UI previews, not new anatomical assets or externally sourced illustrations.

Changes: selected concept groups rendered as 160 × 160 PNG previews using the licensed Human Atlas-derived application renderer. The source-concept/part inventory and capture workflow are recorded in validation/organ-thumbnails/.

## Organ Explorer previews

The `explorer-*.png` images are 640 × 640 transparent renders captured with `scripts/render-organ-previews.cjs`. Heart, brain and liver use the BodyParts3D Whole Body reference above. These previews may differ from the reference used by a dedicated organ explorer.

The left and right lung previews include HRA male lung v1.3 surfaces: Kristen Browne and Heidi Schlehlein (2023), *3D Reference Organ for Lung, Male v1.3*, Human Reference Atlas / HuBMAP.

Additional organ previews are captured from the dedicated source-organ viewers with `scripts/render-source-organ-previews.cjs`, using the same BodyParts3D attribution above. They use product membership corrections already recorded in the application's source metadata. The dedicated liver preview uses that same corrected membership.

Changes for all previews: application tissue materials, lighting, transparent backgrounds and camera framing. Anatomical geometry is unchanged.

`organ-explorer-social.png` combines these previews with the application logo and text for social sharing. Generated by `scripts/render-social-preview.cjs`; the same model attribution applies.
