Build a 3D anatomy explorer from open organ models with a Blender pipeline

The poster (u/samewakefulinsomnia) wanted a better way to see how the body works than flat textbook pictures, and built Bodylang, an app where you chat about your own body and watch it react to everyday situations. They say Claude Opus 5.5 did almost all of the 3D work and the code. It wrote a Blender script pipeline that takes the organs, muscles and vessels from the open Z-Anatomy set and warps them into separate male and female body models. It then built a Three.js scene with shaders that highlight whatever part is being explained, and an animated close-up drawing for each organ. The chat inside the app runs through the user's own Claude Code subscription, mostly on the cheaper models.

The app is live as a web demo and the code is public on GitHub. The poster calls it early, with some body systems still missing. They run it as an interactive desktop background on a second monitor. A commenter singled out a timeline that shows how long coffee and beer stay active. The poster gives no figures for time spent or cost of the build.

The post names the model but not the tool it was driven through, so the setup behind the build is unknown. A commenter asked whether figures like alcohol clearance come from cited rates or are the model's own estimate each time; that question had no answer in the thread, so treat the numbers as unverified.
