From 6f98e266b13216a5d01e6d31fdcd94350a42c20b Mon Sep 17 00:00:00 2001 From: Claude Date: Mon, 6 Jul 2026 15:42:04 +0000 Subject: [PATCH 1/2] =?UTF-8?q?cockpit:=20/ice=20Iceland=20scene=20?= =?UTF-8?q?=E2=80=94=20height-profile=20terrain=20palette=20+=20sky?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add a dedicated /ice route rendering the EXISTING Iceland helix bake (iceland_latest = iceland.helix.soa.gz, already in the manifest) through the same BodyHelix Signed360 decoder — equivalent to /helix?scene=iceland, but a home with height-profile beautification. Client-side render only: no re-bake, no new network fetch. What changed: - Route: /ice → in main.tsx, next to /geo. - Scene-helper unification: the path→scene mapping (/geo→osm, /ice→iceland) now lives in ONE pathScene() helper, read by BOTH fetchSoa() (which bake to load) and isGeoScene (whether to disable server LOD + light the geo beautification), so the two resolvers can never disagree — the file's own comment demanded this. `?scene=` still overrides. - Height-profile terrain palette (geo-scene-gated via a uGeo uniform): colour is driven by per-vertex elevation (display.y), normalized against the ACTUAL measured [uYMin,uYMax] (the Iceland bake is true-scale, not exaggerated — span ~0.0074 with 39% ocean at exactly 0 and a heavily quantized lowland plateau, so [-1,1] normalization would flatten it to all-water) with a sqrt curve to spread the skewed highland tail. Bands: ocean (deep blue) → coast/moss-tundra (the dominant quantized lowland) → brown rock → grey scree → white/pale ice cap, plus a subtle warm "volcano" accent in the mid-high band. Water is separated cleanly at the exact-0 ocean vs first-land boundary. - Colour is HEIGHT-ONLY on purpose: the decoded Signed360 normal is bimodal for the geo bake (measured 77% |n.y|≈0 / 23% ≈1), so it is not a usable continuous slope — classifying rock/scree/volcano from it would produce a binary patchwork. The shade lighting term still uses the normal for form. - Geo relief: a uExag geometry-raise so the true-scale island reads as terrain off the y=0 sea plane, plus a 3/4 default camera for geo scenes. - Procedural sky dome (geo only): a large BackSide sphere with a vertical horizon→zenith gradient shader, rendered first (renderOrder −1, depthWrite off) so terrain paints over it. No external asset (CSP blocks CDNs). - Gating leaves anatomy byte-identical: uGeo==0 → exactly the pre-existing `aColor * shade` and uExag==1 → position unchanged; the sky dome and geo camera are added only when isGeoScene; non-geo scenes keep PAGE_BG. Honest note: true volcano / lava-field / glacier feature classification needs a DEM re-bake carrying feature layers; the warm "volcano" band here is a deliberately-subtle height-derived accent approximation. Verified: `npm run build` (tsc + vite) passes clean; a headless swiftshader-WebGL Playwright screenshot of /ice shows the sky gradient and the Iceland relief with elevation-varied colour; /helix keeps its unchanged title and same graceful behaviour (its body bake is a release-only asset, absent locally).
