## Useful for

- Generate a 3D model of a district and export it as GLB for further use
- Build a base for a city digital twin or GPS marker visualization

## Why it’s here

- Star-counter measurements on 2026-10-09 (UTC), 11:36–13:23: 2566 → 2567 stars (+1). This is the change over that interval.
- Estimated end-of-day forecast: about +8 stars, using observed gains and the previous day.
- Before this, the repository barely got any stars — about 1 per day.
- GitHub Trending TypeScript today: #9, +27 stars.
- About 10 forks a day — people are taking the code.

## Star trust

Star growth looks organic.

Star-trust labels are heuristics based on the repository’s behavior, not a check of every stargazer.

## Numbers

- Forks: 416
- Issues and pull requests: 15
- Watchers: 32
- Average over the last week: 20 per day
- Usual pace: 4 per day
- Stars in the last hour (measured): 0

Magnitude (0–10) measures how fast and how unusually interest in a repository is growing right now. It is not a quality score.
Days are UTC. “So far today” is a fact; “expected by the end of the day” is a forecast.
Summaries and use cases are written by an LLM (DeepSeek V4.1 Flash) from the README and may be inaccurate: verify specific claims (benchmarks, speed, hardware) in the repository itself.
