Human Atlas: Open-Source 3D Anatomy Explorer in the Browser

Repositoryashemag/human-atlasTool

Human Atlas is an open-source, interactive 3D anatomy explorer built with React, Three.js, and shadcn/ui. It breaks down the BodyParts3D reference model into 2,234 selectable meshes across 15 anatomical systems, offering search, layer toggles, and exploded views.

Key points

  1. Interactive 3D visualization featuring 2,234 selectable meshes and 3,432 named concepts derived from BodyParts3D 4.0.
  2. Capabilities include toggling 15 anatomical systems, exploded inventory views, structure isolation, and search.
  3. Optimised rendering pipeline merges geometry batches and uses GPU textures for translation, visibility, and selection to keep draw calls low.
  4. Packaged model consists of approximately 2.29 million triangles, downloading roughly 33 MB of compressed geometry.
  5. Integrates optional WebMCP tools for anatomy inspection and search in compatible browsers.

Why it matters

Rendering massive anatomical models smoothly in the browser typically strains performance due to excessive draw calls. Human Atlas demonstrates how to combine Three.js, React, and GPU texture techniques to make complex, educational 3D visualisations accessible without accounts or external APIs.

Analysis

Human Atlas serves educators, students, and front-end developers exploring large-scale WebGL architectures. It is explicitly positioned as an educational tool rather than for surgical or diagnostic use. The project appears solid and mature, backed by over 2,800 stars, robust test scripts for geometry and layout collisions, and a functional live demo. However, real-world multitouch interactions and physical device performance remain areas with pending verification.
