human-atlas

Human Atlas is a 3D anatomy explorer that runs in a browser tab. It loads the BodyParts3D reference model, 2,234 individually selectable meshes across fifteen body systems, and lets you orbit, hide layers, and search anatomical terms. There is a free hosted demo, and the code is MIT so you can clone and run it yourself.

React, Three.js, and Vite, which means the build output is a static site. Deploy it to Vercel, an S3 bucket, or whatever folder your school already serves. No backend, no database, no API keys. The mesh data is about 33 MB compressed, so first load is the only real performance question.

Students, teachers, and anyone curious where an organ actually sits are the audience. The author states plainly that it is not a diagnostic or surgical tool, which is the right call.

The catch is the license split. The code is MIT but the anatomy data is BodyParts3D under CC BY 4.0, so forking this into a product carries an attribution obligation the MIT code does not cover. The second limit is the model itself: BodyParts3D is one adult male reference, so it shows you an anatomy, not the range of them.
