Create believable procedural pipework, ducts and conduits in Three.js: mains, branches, bends, flanges, valves, supports and hangers, colour-coded by service. Use for any pipe, duct, cable tray or conduit on a structure, a building, a plant, a ship or a street.

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

# Pipes

Target: Three.js 0.187.0, WebGPU renderer (`three/webgpu`) and TSL node materials (`three/tsl`); WebGPU only, no WebGL fallback, no GLSL strings.

Create pipework that reads as an engineered service, not as decoration. Build it from procedural geometry, drawn through one pipework system (an instanced unit-shape set, below). Do not model each pipe by hand with separate cylinder meshes.

The target is a **working service of a large engineered place**: everything carries something (air, water, coolant, steam, power), goes somewhere, and is supported, joined and maintained.

## Core priorities

1. the route: where the pipe comes from and goes to, along structure
2. support: nothing hangs in the air
3. joints: flanges where lengths meet, bends where it turns
4. clearance: never across a walkway or a door at head height
5. colour: one colour for one service, the same everywhere
6. valves, meters and tags: a few, where someone would need them
7. the small things last

## Vocabulary

- **Main**: a large pipe (0.6 to 3 m across) along a street, a soffit or a rack; **branch**: a smaller pipe off it, at a tee; **stub**: a short branch capped or into a wall.

How to install

The exact contents, by fingerprint
mdr add wolffe/three.js-skills/pipes@sha256:da7d587202378888

The line at the top of this page pins the label git:20261031.845cf45, 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.
