Everyone's making motion graphics with Claude Opus 5.5.
Nobody's talking about what it's scary good at: 3D machine teardowns.
This planetary gearbox came out of ONE prompt. Real gear teeth, cut-open housing, exploded view, labels. One HTML file that opens in your browser.
I ran it 4 times in fresh Claude Code sessions (Opus 5.5 and Sonnet 5.5). Every run worked first try.
🔖 Bookmark it. Swap the machine name on the first line and run it. I've only verified the gearbox so far, so reply with what yours builds.
Full prompt 👇
MACHINE = "planetary gearbox"
Build a premium 3D animated cutaway of the MACHINE above as ONE self-contained file: index.html (no build step, no other files). It must open by double-clicking.
Tech
- Three.js 0.160.0 from the unpkg CDN via an importmap ("three" and "three/addons/").
- Use OrbitControls, RoomEnvironment + PMREMGenerator for reflections, ACESFilmic tone mapping, sRGB output, soft shadows, antialias, devicePixelRatio capped at 2. Resize with the window.
Model (this is what makes it look expensive — don't cut corners)
- Model every real part of the MACHINE with correct proportions and real geometry: e.g. gears get actual teeth built from ExtrudeGeometry with a proper tooth profile, shafts, bearings, housings, bolts. No placeholder boxes or plain spheres standing in for parts.
- Real materials with MeshPhysicalMaterial: brushed steel (metalness 1, roughness 0.3), dark anodized aluminum, brass or bronze accents, matte rubber where it belongs. Slight color variation between parts so they read separately.
- Show the inside: cut the housing open (half shell or a clipping plane) so the moving parts are visible.
- Parts must mesh and move correctly relative to each other (correct gear ratios, matching rotation directions).
Animation (seamless 12-second loop)
- 0–4 s: assembled machine running, slow camera orbit.
- 4–8 s: exploded view — parts slide apart along their axis with easing, still turning; a small floating label (HTML overlay, clean sans-serif) names each major part.
- 8–12 s: parts ease back together, loop restarts without a jump.
Look
- Dark studio background with a subtle radial gradient, a soft ground shadow, one warm key light and one cool rim light. First frame must already look like a product render, not a demo.
- A small title in the top-left with the MACHINE name, and one line under it explaining how it works in plain English.
When done: list the parts you modeled and how to change MACHINE to something else (e.g. "4-stroke engine", "mechanical watch movement", "differential").
