Fog of Knowledge: The Game (v3, graphics overhaul). DO NOT MERGE yet

This adds a new page, research/fog-of-knowledge/game/, with a real-time 3D open world: a human explorer, real physics, and discoveries that clear the atlas fog. The only other change is one header link in research/fog-of-knowledge/index.html.

Play (Nemesis): http://127.0.0.1:8000/fog-of-knowledge/aa84436da26f2d882e1886cd729930788771ee40/game/index.html

v3: graphics overhaul (commit aa84436)

• Character: a rigged, animated CC0 human (Quaternius Universal Animation Library) loaded with GLTFLoader and AnimationMixer.
  • 14 clips: idle, walk, jog, sprint, jump start/loop/land, swim, swim idle, throw, strike, pick-up, interact and death.
  • Clips blend by speed and state. Bind-pose zone colouring dresses the figure (boots, trousers, tunic, skin, hair).
• Animals: smooth PBR procedural animals (no CC0 animal models were vendored).
• Lighting:
  • ACES filmic tone mapping in sRGB with PBR materials.
  • A sun with soft PCF shadows that follow the player, a hemisphere light and a golden hour.
  • A blue moonlit night with stars.
  • Fires and kilns use flickering point lights (Ultra also gives the nearest fire a shadow).
• Sky: a tuned Preetham Sky. Height and distance exponential fog blends into the sky horizon. A procedural cloud layer, a moon and stars. Rain and snow weather.
• Water: the three.js Water addon (planar reflection and normal map) on High/Ultra. Animated shoreline foam, wet sand and an underwater tint and fog.
• Terrain: smooth analytic normals, per-biome noise detail, rock on slopes, snow on peaks.
• Vegetation:
  • Instanced, wind-swaying grass near the player.
  • Pine, broadleaf, palm and dead trees with leaf sway.
  • Bushes, flowers, boulders, stones and sticks.
• Effects:
  • Fire, smoke and ember particles; flint and pyrite sparks; landing dust; water splashes.
  • Post-processing: UnrealBloom, then OutputPass, then FXAA (High) or SMAA (Ultra), then grade/vignette.
• UI:
  • A title screen over an animated 3D flyover with a golden-hour time-lapse.
  • Glass HUD and a glowing discovery popup.
  • Settings (gear button / Esc) with Low, High and Ultra quality (saved in localStorage, default High), an fps counter and credits.

Verified (headless Edge on Michael's PC, GTX 1070, D3D11, 1920×1080, via the Nemesis URL above)

• The page loads. The title screen shows. Play works. The human model loads and WASD/sprint/jump move the player about 15 m.
• Building a campfire and striking flint triggers the Fire making discovery, and the popup shows.
• The atlas page still shows 6,360, and the header link points to game/index.html.
• The only console error is the favicon 404.
• fps: Low 144 (vsync cap), High 125, Ultra 106. High at night with a burning fire runs at about 93.

Scope and safety

Served sha256 hashes at this commit match main (f188078) for:

• the atlas data (atlas-navigation.json, atlas-display.json, atlas-families.json)
• styles.css and app.js
• circuit-routing.js, circuit-worker.js, circuit-painter.js and massive-atlas.js

git diff --stat main -- research/fog-of-knowledge ':!research/fog-of-knowledge/game' shows only index.html, with a 1-line change.

No arena.db, no CODEX_NODE_EXPANSION, no PR #108.

Assets and licences

• three.js r160 and these examples addons, vendored and imports rewritten to the local module: Sky, Water, GLTFLoader, BufferGeometryUtils, SkeletonUtils, EffectComposer and its passes, UnrealBloom, OutputPass, FXAA/SMAA and waternormals.jpg. All MIT; see vendor/LICENSE-three.txt.
• Quaternius Universal Animation Library mannequin: CC0, by Quaternius, via the github.com/J-Ponzo/gltf-universal-animation-library mirror.
  • Trimmed to 14 clips and stored as assets/human.gltf.json with an embedded buffer, because Nemesis does not serve .glb/.gltf.
  • See assets/LICENSE-Quaternius-UAL-CC0.txt and assets/CREDITS.txt.
• Everything else (terrain, plants, animals, clouds, particles) is procedural code.

Rough edges and known limits

• No fish. No SSAO.
• Animals are procedural, not rigged.
• Clouds are a single layer.
• Shadow casters don't sway with the wind.
• The first load fetches about 2.7 MB for the human model.
