Fable 5.1 World Modeling
GitHub repository for creating browser-native reconstructions of real places using open data and public reference imagery.
Intelligence analysis by Qwen 2.5 (3B)
GitHub repository for generating 3D models of real-world places like Union Square in San Francisco and Higashiyama in Kyoto using open data and public reference imagery.
This is a place where people can make 3D models of real places like parks and buildings using information from the internet and pictures. It's like building a toy city in your computer!
Analysis
Reconnaissance
The process begins with parallel research agents pulling OpenStreetMap geometry, USGS elevation, transit and street specs, and a storefront census with per-fact sources and confidence levels. This data is used to create a comprehensive understanding of the place being modeled.
Offline Asset Generation
Blender-as-a-library (bpy) scripts emit optimized GLB kits: façade modules, street furniture, vehicles, vegetation, retail fixtures, pedestrian body parts. These assets are pre-generated and stored for quick access during the runtime process.
Runtime
A pure Three.js app assembles terrain, streets, façades, props, crowds and traffic from JSON specs. This app is designed to be run in a browser, allowing users to explore the 3D models interactively.
Camera-Match QA
Playwright drives the real app, screenshots fixed viewpoints, and diffs them against free-licensed photographs taken from the same spot. Independent reviewer agents (architect, geographer, technical artist, interaction) file reports that drive the next fix cycle. This ensures the accuracy and realism of the 3D models.
Key points
- The repository contains scripts for generating 3D models of real-world places.
- The models are created using OpenStreetMap data and public reference imagery.
- The models are validated by independent reviewers and compared to real photographs.
- The models can be used for urban planning, tourism, and education.
- The models are built using a pure Three.js app, which is run in a browser.
The 3D models can help people plan cities better and make virtual tours of places they can't visit in real life.
If the models are not accurate, it could lead to misinformation and misguidance in planning and tours.
