Vet Atlas

Open 3D veterinary anatomy, built for studying

A free atlas of dog, cat, cow and horse anatomy. Every bone, muscle and organ is a selectable piece with its Latin (NAV) name, a description, the diseases that affect it and real images.

What's inside

Species	Dog, cat, cow, horse
Systems	Skin, muscles, organs and skeleton, stacked as dissection layers
Structures	~340, each with its NAV name in Latin
Diseases	~125, linked to the structures they affect, with references
Images	~190 specimens, radiographs and histology, all with license and attribution
Languages	English and Spanish

• Dissect from skin to bone with one slider, or show any layer as a ghost.
• Click any piece in the model to open its entry; the selection is the URL, so every view can be shared.
• Search any structure or disease in either language with ⌘K / /.
• Anatomical views (lateral, dorsal, cranial…) from the orientation rose, plus isolate and explode.
• Works on a phone, no account, no ads.

Every entry shows its review status: draft, based on sources (checked against the references listed at its end) or reviewed by a veterinarian, and lists its sources at the end. It is study material, not a substitute for diagnosis or veterinary consultation.

Run it locally

git clone https://github.com/Ketbome/vet-atlas.git
cd vet-atlas
pnpm install
pnpm dev

Command	What it does
pnpm dev	Dev server (English at /, Spanish at /es)
pnpm build	Static export to out/
pnpm validate	Content integrity and GLB mesh names
pnpm lint · pnpm typecheck	Lint and types (run pnpm next typegen first)
pnpm models:<species>[-<system>]	Rebuild a species' GLBs (needs SKETCHFAB_TOKEN)

How it works

Next.js 16 static export served by GitHub Pages, no database and no server. Content is plain files under content/ (JSON + MDX) validated with Zod; the viewer is React Three Fiber with one GLB per species and system, where each mesh is one structure.

app/[locale]/        routes: home, species, system viewer, structure, disease
components/viewer/   3D viewer: scene, layers, camera, structure tree
components/atlas/    site chrome, search, MDX, badges
content/             species, systems, structures, diseases, media, sources
lib/content/         Zod schemas, loaders, search index
scripts/             model builds, content validation, CT tooling
messages/            UI strings per locale

Contributing

You don't need to touch code to help. Every page has an Edit on GitHub link that opens the right file:

• Fix or translate a text: edit the .mdx, open a pull request.
• Add a structure or a disease: a folder with meta.json and one .mdx per language.
• Review as a veterinarian: check an entry and flip review.status to reviewed.

Details in CONTRIBUTING.md.
