Richard Zink ee56f2a1c8 moon: real lunar map (CC BY 4.0) with correct near-side geometry - the old normal sign lit the far side, so the disc came out black; stars are now occluded by the disc, sun and moon discs drawn at 12x physical without changing surface brightness; build.py inlines the map as a data URI 2026-10-11 22:46:35 +02:00
Richard Zink efd4db47cb geo: cell manifest geo/cells_v1 - cached road/place fast paths check one small record instead of reading every multi-megabyte raw cell 2026-10-11 21:34:52 +02:00
Richard Zink 6d21b37e8f progress logs behind CONFIG.debug, CONFIG.antialias + high-performance context, cheaper cloud sampling (skip far detail octave and redundant self-shading probe), brighter night contrails via CONFIG.flights.contrailNight, window.__flightDbg counters, real sun/moon by default 2026-10-11 18:42:48 +02:00
Richard Zink 113e4c522d airliner mesh is generated in-repo: tools/plane_gen.py writes vendor/plane3d.js (480 tris, CC0, same unit extent as the old Grab3D derivative); attribution updated 2026-10-11 18:42:48 +02:00
Richard Zink 499c00d8b1 standalone without our server: basemap and DEM load from the CORS-enabled upstreams, same-origin proxy only when a probe proves it exists; drop dead kumi.systems mirror 2026-10-11 16:02:10 +02:00
Richard Zink 4369afd3ef lighting: remove the palette terrain model - physics is the only lighting, themes tint it through THEMES[theme].lighting; debug panel shows the active palette and its tint/gain; credits no longer claim VIIRS 2026-10-11 15:39:42 +02:00
Richard Zink 6eb25bdd03 physical lighting, volumetric clouds, terrain shadows, pixel-art render scale 
- atmosphere: physical terrain lighting (air mass, Rayleigh beam colour,
  skylight, moon, starlight floor), aerial perspective for terrain and
  cloud deck, configurable haze/albedo/ambient gains
- clouds: march the deck in height instead of ray distance, IGN dither
  (no per-frame flicker), per-step height jitter, 4-octave fbm renormalised,
  softer density threshold, distance softening as a procedural mip,
  grazing path clamp, cloud shadows on the ground (cloudShadowDensity/
  Floor/Ambient) and cloud haze factor
- terrain: self-shadows from the elevation field (penumbra + shadow floor),
  soft mosaic rim (edgeFadeTiles), east/west axis corrected (+X = west)
- lights: per-object twilight switching for cars, city dots and ground blocks
- flights: contrail width 620 m, fade to zero by contrailFadeKm, aircraft
  size decoupled from trail width, count halved
- render: CONFIG.renderScale with integer upscale + image-rendering: pixelated
- data: nginx overpass proxy + cache, per-mirror cooldown ladder, ring-based
  cell ordering (disc fills evenly), settlements fetched before roads,
  interim chain persistence, two worker lanes (car/city) with progress logs
- removed: NASA VIIRS night-lights layer (fetch, canvas, texture, uniforms)

Richard Zink cd460ec100 city lights: report buildMs in __cityDbg (measured: 17.5k places -> 46.7k points in 1.5ms) 2026-10-10 14:30:32 +02:00
Richard Zink 75dc5ed5b9 overpass: drop dead kumi.systems mirror (500 + no CORS) from endpoint ladder 2026-10-10 13:46:49 +02:00
Richard Zink 73d5c3f6a7 settlements: drop costly relation tier from place query (timed whole cells out), 3 mirror rounds with jitter, per-cell progress log; verified live: 1747 places -> 3855 lights 2026-10-10 13:37:35 +02:00
Richard Zink aebe311e32 cache derived geometry: merged road chains + settlement list persisted with cell fingerprints; two-tier best-first road stitching (raw-node headings, permissive interchange pass); fast path skips all raw parsing on unchanged data 2026-10-10 13:15:03 +02:00
Richard Zink 26bd5bbc59 contrails: keep visible at night as dimmed moonlit streaks (42% of night ramp); city debug counter + pending-terrain log 2026-10-10 11:50:07 +02:00
Richard Zink 1879a6912a contrails: distance-scaled ribbon width (sub-pixel fix), brighter head, far longer visible range 2026-10-10 11:12:38 +02:00
Richard Zink d0aa86ce9b flights: full CONFIG.flights parameterization (altitude, count, speed, holds, destination weights, contrail chance/alt/life/width) + curved random-destination routing 2026-10-10 11:02:58 +02:00
