Portable Agent Skill by Hailey. It builds a real, orbitable Three.js building that assembles itself: brick courses, timber frame, dougong, layered eaves, procedural PBR materials, and close-up cameras.

中文：给 Codex / Claude Code / Cursor 用的开源 skill。输出是可运行的三维古建网站，不是贴图揭幕，也不需要 API key。

GitHub README cannot play a repo .mp4 inline, so the motion preview is a GIF. Click it (or the link) to play the full video.

• A solid 3D miniature, not a video on a plane
• Construction driven by one 0–1 timeline: play, pause, scrub backward, replay
• Procedural brick, wood, plaster, tile, stone, bronze — no paid models
• Orbit, zoom, and detail cameras for eaves and stone lions
• A Vite + React + Three.js starter you can run with npm ci && npm run dev

The bundled clock tower is a working example, not a historical reconstruction and not the only design this skill can make.

Copy this folder into the agent skills directory, then start a new session:

git clone https://github.com/lhlGitHub/threejs-architecture-effects.git
cp -R threejs-architecture-effects ~/.cursor/skills/

Then ask:

Use $threejs-architecture-effects to make a Chinese pavilion like the starter: red walls, dark-green tiles, built storey by storey, orbitable, with eave close-ups.

Other useful prompts:

• Keep the current tower shape and cameras. Only refine eave thickness, timber, and the clock faces.
• Turn the template into a two-storey lakeside pavilion. Keep timber and tile assembly. No clocks or lions.

Needs Node.js 22.13+, npm, and a WebGL2 browser.

git clone https://github.com/lhlGitHub/threejs-architecture-effects.git
node threejs-architecture-effects/scripts/scaffold.mjs ./my-building
cd my-building
npm ci
npm run dev

The scaffold copies assets/starter/ into a new directory and refuses to overwrite an existing one. It does not install packages or start a server.

Controls: drag to orbit, scroll to zoom, timeline to scrub, 飞檐细赏 / 石狮近观 for close-ups.

1. Write an assembly plan: foundations → frame → masonry → decks → upper walls → brackets / eaves / tiles → ornament.
2. Model the finished silhouette first so parts share dimensions and nothing floats.
3. Give every solid piece a start, duration, and travel. Color and shadow shaders share one progress value, so seeking is deterministic.
4. Author materials separately (color, roughness, micro-height). Do not hide crude joints with fog or bloom.

• Procedural geometry only. No paid model service, no background music in the starter.
• Video export is not included; the template is an interactive site.
• Desktop-oriented. Do not claim museum quality, historical accuracy, or universal 60 FPS from one machine.
• npm packages keep their own licenses. This skill does not vendor node_modules.
