What began as a Japanese translation of Human Atlas is now JINTAI 3D, with Z-Anatomy models, peripheral nerves, quizzes and experimental joint motion. But most of my time now goes into checking whether the names and explanations are actually correct. Part 4 of the series.
BodyParts3D, published in Japan in 2009, was found by a Belgian medical illustrator, rebuilt in Blender, and grown into Z-Anatomy by engineers and translators. Then in 2026, an AI post on X led me back to it. Open source isn't free stock: it's a relay of other people's work. Part 3.
A 3D human body you can pull apart in a browser. I went looking for who made it and how, and ended up at BodyParts3D, published for free by Japanese research institutes, and TARO, a body model built to study mobile-phone radio waves. Part 2 of two.
A 3D anatomy viewer scrolled past on X, built with GPT-6 Astra. I localised it into Japanese and put it on Cloudflare instead of Vercel. The question it left me with — who made the underlying body data? — is Part 2.
