# Credits: the world events' pictures

Every picture the event layer and events/gallery.html can use, where it comes from, who made it and its licence.
Rendered ones are drawn from the 3D models by `scripts/build_event_sprites.py` (prototypes/render_events.html);
drawn ones are made in canvas by `eventsprites.js`. Downloads live in `data/local/downloads/` (not in git).
The building pictures (assets/buildings) are credited in scripts/build_buildings.py: Kenney and KayKit, CC0.

## Universe implementation (local branch)

- The original brand fonts are now self-hosted in `assets/fonts/`: **New Rocker**
  (Pablo Impallari, Brenda Gallo and Rodrigo Fuenzalida), **Lilita One** (Juan
  Montoreano), and **Nunito** (The Nunito Project Authors), under the SIL Open
  Font License 1.1.
  Full upstream copyright/licence files are retained there. Sources:
  [Google Fonts New Rocker](https://github.com/google/fonts/tree/main/ofl/newrocker),
  [Lilita One](https://github.com/google/fonts/tree/main/ofl/lilitaone),
  [Nunito](https://github.com/google/fonts/tree/main/ofl/nunito). CSS retains
  the supplied language subsets and weights; WOFF2 files are unmodified.
- Earth rendering now self-hosts the exact previous CDN versions of
  [d3-array 3.2.4](https://github.com/d3/d3-array/tree/v3.2.4),
  [d3-geo 3.1.1](https://github.com/d3/d3-geo/tree/v3.1.1),
  [topojson-client 3.1.0](https://github.com/topojson/topojson-client/tree/v3.1.0),
  and [world-atlas 2.0.2](https://github.com/topojson/world-atlas/tree/v2.0.2),
  under their ISC licences (`vendor/LICENSE-*`). World Atlas redistributes
  [Natural Earth](https://www.naturalearthdata.com/about/terms-of-use/)
  public-domain map data. Source URLs and SHA-256 hashes are recorded in
  `vendor/earth-dependencies.json`.

- The Moon/Mars assets above are retained for the integrated universe in `index.html`.
  `*-small.jpg` are 512×256 derivatives for distant bodies, by Pin World.
- **Progressive close-up surfaces:** Moon colour now derives from NASA's Scientific
  Visualization Studio [2025 CGI Moon Kit 8k and 16k sRGB maps](https://svs.gsfc.nasa.gov/4720/).
  Mars colour derives from the 1km ancillary JPEG of
  [Mars Viking Colorized Global Mosaic (MDIM2.1)](https://astrogeology.usgs.gov/search/map/mars_viking_colorized_global_mosaic_232m),
  **NASA Ames / USGS Astrogeology Science Center, public domain** (the product
  metadata lists no use constraints). This is an artistically colorized mosaic;
  the downloaded derivative is 1km/pixel, rather than the full 232m product.
  Its published equirectangular affine transform registers the odd-sized raster
  to planetocentric latitude and positive-east longitude. Pin World applies a
  white/black-preserving warm gamma palette and derives every Mars level from
  the same georeferenced 16k map, including the distant overview.
  These are visualization assets, not uniform-resolution measurements.
  The original source URLs and SHA-256 hashes are
  in `assets/planets/detail-v1/sources.json`. `scripts/build_planet_detail.py`
  applies the same warm palette grading to the matching 512px/2k basemaps and
  4k/8k/16k padded JPEG tile pyramids. The Moon's 16k close-up tier comes from
  the matching larger 2025 map; its lower-tier assets retain their existing bytes.
  NASA fills the color map beyond 70 degrees latitude with lower-resolution
  monochromatic albedo; these visual assets are not uniform-resolution survey
  products. No upscaling is used. Original downloaded
  sources remain in ignored `review/planet-sources/`; runtime uses local tiles.
  The surface credit link names NASA and USGS. Earlier local releases used
  [Solar System Scope's 8k Mars map](https://www.solarsystemscope.com/textures/),
  **© Solar System Scope, [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/)**;
  that source is replaced in the current integrated Mars colour pyramid.
- Venus, Europa and Titan `*-2k.jpg` and `*-small.jpg` are **original decorative
  illustrations**, generated by `scripts/build_universe_textures.py` (Pin World,
  ours). They are not scientific maps. Those worlds are locked previews.
- H3 coordinates use `h3-js` **4.3.0** (Apache-2.0,
  [source](https://github.com/uber/h3-js/tree/v4.3.0), licence in
  `vendor/LICENSE-h3`). The immutable catalogue is generated with Python `h3`
  **4.3.1**, using resolution 2. Region sectors are Pin World gameplay partitions,
  not official IAU boundaries.
- Universe rendering uses three.js **0.185.0** (MIT,
  [source](https://github.com/mrdoob/three.js/tree/r185), licence in
  `vendor/LICENSE-three`). The revision matches the existing globe.gl bundle.
- Radius metadata uses volumetric mean radii from the NASA/JPL
  [planet parameters](https://ssd.jpl.nasa.gov/planets/phys_par.html),
  [Moon fact sheet](https://nssdc.gsfc.nasa.gov/planetary/factsheet/moonfact.html),
  and [satellite parameters](https://ssd.jpl.nasa.gov/sats/phys_par/).
  Scene distances, body sizes and orbits are compressed for navigation.
