Open-source 3D anatomy explorer: 2,234 selectable BodyParts3D meshes

summary

Human Atlas is an open-source web application that allows users to explore human anatomy through an interactive 3D model. It uses React, Three.js, and shadcn/ui to render over 2,000 individually selectable meshes from the BodyParts3D dataset. The project aims to provide an educational tool for searching and visualizing anatomical systems in a browser-optimized environment. By simplifying geometry and batching GPU textures, the application maintains performance without sacrificing anatomical detail.

key points

1. The application features a robust search and filtering system that lets users isolate specific anatomical structures or toggle entire systems. It includes an 'exploded' view that separates components for better visibility of internal structures.
2. Technical optimization is achieved by merging geometry into batches and using GPU textures to handle visibility and selection. This approach reduces draw calls and ensures the scene remains responsive even with millions of triangles.
3. The project is built for accessibility and education, utilizing CC BY 4.0 licensed data and providing a complete pipeline for rebuilding or optimizing the 3D geometry.
