Explain how a machine works as an interactive isometric 3D cutaway. Use when the user asks how an engine, turbine, reactor, pump, clock, motor or any mechanism works and wants to see it, or types "/anatomy <machine>", for example "/anatomy explain how a big airliner turbofan engine like the A380's makes thrust, interactive". Produces a shareable three.ws link with real moving parts, shader effects (fire, exhaust, plasma, water, steam, sparks, arcs), flows, a section cut, an exploded view and a…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Anatomy: machines as interactive cutaways Describe a machine in one line and get back an interactive isometric wireframe cutaway on three.ws. Visitors can rotate it, step through a guided tour, explode it, cut it open, switch to x-ray and click any part to read what it does. Moving parts really move, and the physics is drawn with WebGL shaders. The result is a permalink such as `https://three.ws/anatomy/<id>`. Share it as the answer. It works on desktop and phones, with no account needed to view it. ## Two ways to build one ### 1. You write the spec (best quality, recommended) You know the machine. Write the spec yourself and publish it. 1. Read [reference.md](reference.md). It is the full spec format: parts and shapes, motion, effects, flows, the tour and the quality bar. The server validates against exactly these rules. 2. Write one JSON object for the machine the user asked about. If they named a real machine (for example the Rolls-Royce Trent 900 on the A380), model that machine and its real proportions, stage counts and numbers. If they were vague, choose the most iconic real example and say which in `subtitle`. 3. Publish it: ```bash …

How to install
mdr add nirholas/three.ws/anatomy@sha256:cbce16e48252311aThe line at the top of this page pins the label git:20261104.88de929, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
