tools/globe_capture.html — standalone Cesium page that loads H3 res4
data from R2 via DuckDB-WASM and exposes the viewer for Playwright.
tools/capture_globe_rotation.py — Playwright script that rotates the
camera 360°, captures frames, and stitches into animated WebP via
img2webp (ffmpeg's libwebp_anim doesn't produce proper multi-frame
WebP). Configurable frames, duration, quality, viewport size.
Current defaults produce a 120-frame, 15-second loop at 800x500,
~3.8 MB WebP. Run with:
python -m http.server 8765 --directory tools/
python tools/capture_globe_rotation.py

Summary
tools/globe_capture.html— standalone Cesium page with DuckDB-WASM that loads H3 data and exposes the viewer for Playwrighttools/capture_globe_rotation.py— captures 360° rotation frames and stitches animated WebP viaimg2webpWhy check this in
The animated globe hero (PR #69) will need periodic re-capture as we tweak camera angle, rotation speed, point styling, or when data updates. Having the tooling in-repo means anyone can regenerate it.
How to use
Tunable parameters
--duration— loop length in seconds (higher = slower rotation)--frames— frame count (more = smoother)--quality— WebP quality 0-100 (lower = smaller file)--width/--height— viewport dimensionsDependencies
