Разработчики представили интерактивный 3D-атлас человеческого тела с детализацией до 2234 отдельных элементов

An interactive 3D anatomy explorer built with React, Three.js, and shadcn/ui. Take the BodyParts3D adult male reference apart into 2,234 individually selectable meshes, explore 15 anatomical systems, and search 3,432 named concepts. Explore the live demo Orbit, zoom, and select structures directly on the body. Toggle individual systems or use skeleton and organ presets. Move from assembled anatomy to a spaced inventory of every visible piece. Search anatomical names and source identifiers. Isolate a selected structure and read its details. Use compact controls and detail panels on mobile. Requires Node.js 22.13 or newer. No API keys or accounts are needed. npm ci npm run dev Open http://localhost:3016. To build the static site, run npm run build; the output is in dist/. npm run check node scripts/validate-atlas.mjs node scripts/validate-interactions.mjs npm run build Validation covers mesh buffers, names and concept membership, nonoverlapping exploded layouts at desktop and mobile aspect ratios, search and inspection contracts, and tap-versus-drag handling. Browser interaction checks have exercised selection, system controls, search, isolation, rotation, and 390×844, 320×568, and 844×390 layouts. Phone controls stay clear of the exploded inventory, and isolated structures fit the space above or beside the detail panel. Physical-device performance and real multitouch hardware have not been tested. The current viewer uses BodyParts3D 4.0, an adult male reference anatomy, licensed CC BY 4.0. It does not represent every human structure or variation. Individual source meshes are distinct from named concepts, which may group multiple meshes. Descriptions distinguish general system context from individual organ explanations. Geometry is simplified for browser performance while retaining every source mesh. The packaged model contains 2,288,268 triangles and downloads approximately 33 MB of compressed geometry. Full credits, source links, and adaptation details are in ATTRIBUTION.md. This is an educational explorer, not a diagnostic or surgical tool. Geometry is merged into batches. Per-structure GPU textures control translation, visibility, and selection, while component geometry supports accurate picking. Exploded layouts pack only the visible pieces. Rendering updates when the scene changes; orbit controls remain responsive without thousands of separate draw calls. The optional WebMCP tools expose anatomy search and inspection in compatible browsers. The visible interface works without them. The repository includes browser-ready geometry. Rebuilding it is optional: obtain the official BodyParts3D OBJ archive and English metadata tables, prepare the joined concepts and display-system mappings, run scripts/convert-anatomy.py, then node scripts/optimize-anatomy.mjs and node scripts/compress-models.mjs. Simplification uses a 0.2% relative error limit per structure. Import this repository into Vercel as a Vite project. The included vercel.json configures npm ci, npm run build, and the dist output directory. It can also be served by a static host. Original application code is released under the MIT License. The anatomy data has its own CC BY 4.0 license; preserve the attribution when redistributing it. Third-party dependencies retain their respective licenses. Issues and pull requests are welcome. Please include reproduction steps and browser/device details for interaction problems.
