fable51-worlds: worlds via code, from Fable 5.1

gist

PhiloLabs published fable51-worlds, a public repo of explorable browser-native reconstructions of real places. Autonomous Claude Fable 5.1 agent swarms research, model, and quality-check each world, then ship it as a plain Three.js app. The first world is Union Square, San Francisco: real OSM terrain and street grid, 129 named storefronts, working traffic lights and cable cars, and two interiors. The rerunnable pipeline covers reconnaissance, Blender GLB kits, a Three.js runtime, and Playwright camera-match QA against photographs. There is no game engine or proprietary 3D tiles.

ideas

• Worlds are code, not a game engine. Each reconstruction ships as a plain Three.js app built from OpenStreetMap, USGS elevation, and generation scripts that live in the repo.
• Fable 5.1 swarms own the pipeline. Reconnaissance, Blender GLB kits, runtime assembly, and camera-match QA are checked in so the same stages can be re-run.
• The first world is Union Square. Real Powell–Geary–Post–Stockton grid, 129 named storefronts, traffic and cable cars, plus Apple and Nintendo interiors.
• QA is camera-matched photographs. Playwright screenshots fixed viewpoints and diffs them against free-licensed photos; independent reviewer agents file the next fix cycle.
• Provenance stays explicit. MIT code and generated assets; OSM ODbL and USGS 3DEP geometry; reference photographs are not redistributed.
