Billion-Piece Manhattan - The Entire Island, Alive\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate a maximum-ambition Three.js environment of the ENTIRE island of Manhattan, alive, from the Battery to Inwood, rendered as one continuous explorable object at golden hour. The spectacle is total scale plus continuous zoom: the first frame shows the whole island at once like the world's most detailed aerial photograph, and the camera can then dive seamlessly from that god view down toward street level where traffic moves, ferries cross and rooftop water towers catch the sun. This must not be a single district, a skyline billboard, a low-poly slab city or a fog-hidden partial model. It is the complete island.\n\nThe goal is the visual impression of a billion individually considered pieces: tens of thousands of buildings each with a real footprint, massing and roofline; the true street grid with avenues and cross streets; Central Park as a complete green world; every major bridge; piers, highways, stadiums, cemeteries, tank farms of rooftop water towers, and rivers full of traffic. Achieve this through brutal instancing discipline, procedural building generation, merged districts and nested LOD, not through raw counts.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Everything procedural; no external data files, images or models - approximate the real geography convincingly from knowledge.\n\n#### FIRST FRAME - THE WHOLE ISLAND IN ONE IMPOSSIBLE IMAGE\n- Open on the complete island from high above the southwest, sun low over New Jersey: the full length of Manhattan receding to the north, Downtown and Midtown clusters blazing with lit glass, Central Park a perfect green rectangle, the Hudson and East rivers wrapping it in gold-flecked water, all bridges visible.\n- The island must read as dense and real: the famous skyline silhouettes recognizable at a glance (One World Trade, Empire State, Chrysler, the Midtown supertalls, the Flatiron wedge), the street grid etched in shadow, ferry wakes stitching the rivers.\n- The frame is full edge to edge: Brooklyn and Queens rooftops fading into haze east, New Jersey west, the harbor and a hint of the Statue of Liberty south.\n- No menus, titles or reveals. The island is simply there, complete.\n\n#### THE ZOOM IS THE SPECTACLE\n- Design the entire experience around one continuous zoom range with no loading seams and no popping that breaks belief: from whole-island orbit, through district level where individual towers separate, down to neighborhood level where streets carry visible moving traffic, water towers and rooftop details resolve, and window-scale texture appears on the nearest buildings.\n- At the closest tier, the nearest few blocks must genuinely reward inspection: cornices, fire escapes, rooftop HVAC and water towers, taxi streams, walk lights implied by crowd pulses, tree pits, awnings.\n- Transitions between LOD tiers must be smoothly cross-faded or geo-morphed. The viewer should feel one coherent world, not tiles swapping.\n\n#### THE ISLAND, HONESTLY BUILT\n- Respect the real macro-geography: the tapering southern tip, the grid rotating north of the Village, Broadway cutting its diagonal, Central Park's exact proportion mid-island, the Harlem street rhythm, the ridge and green of the north end, the widening and narrowing of the island.\n- Landmark set with true silhouettes and placements: One World Trade and the Downtown cluster; the Brooklyn, Manhattan and Williamsburg bridges; the Flatiron; Empire State; Chrysler; Grand Central's low mass among towers; the Midtown supertall row; the UN slab on the East River; the Met in the park edge; the George Washington Bridge at the top of the island.\n- Everything else is procedurally generated but honest: block-correct building heights by district, tenement rows, avenue canyons, piers and the West Side Highway, stuyvesant-style superblocks, project towers uptown, and green pockets (Washington Square, Bryant Park, Riverside strip).\n- Central Park is a complete sub-world: reservoir, lakes, meadows, tree masses, paths, ballfields, all readable from altitude and pleasant at mid-zoom.\n\n#### A CITY THAT IS VISIBLY ALIVE AT EVERY SCALE\n- Rivers: ferries, barges and tour boats moving with wakes; helicopters tracking the shoreline; the harbor busy to the south.\n- Streets: avenue-scale traffic flows as animated streams with taxi-yellow concentration, red brake ripples and headlight sparkle in shaded canyons; crosstown streets pulse differently from avenues.\n- Air and light: sun glinting and sliding across thousands of glass faces as the camera orbits, cloud shadows crossing districts, contrails, a jet on approach in the distance, birds over the park.\n- Detail-tier life: at close zoom, steam from street grates, rooftop flags, moving elevated traffic on the FDR and West Side Highway.\n\n#### LIGHT AND MATERIAL\n- Golden hour as default: long shadows etching the grid, warm masonry versus cool glass, the two rivers as sheets of moving glitter, park foliage deep and saturated.\n- Materials must vary by district and era: dark glass supertalls, green-roofed pre-war stone, red-brick tenements, white terracotta classics, weathered piers.\n- Windows carry believable variation: sun mirrors, interior warmth beginning to show in shadowed faces, no two towers identical.\n\n#### EXPLORATION AND CONTROLS\n- Orbit, pan and zoom active immediately with beautifully tuned inertia across the whole zoom range; one reset returns to the hero island view.\n- Camera presets: full-island hero; Downtown harbor orbit; Midtown canyon dive; Central Park overview; East River bridge sweep; George Washington Bridge north view back down the island.\n- Compact controls only: light (golden hour \u002F clear noon \u002F dusk with the city lighting up window by window), river and street traffic density, and photo mode.\n- Dusk mode is a required showpiece: thousands of windows igniting progressively, bridge necklaces lighting, streams of headlights.\n\n#### PERFORMANCE AS A FIRST-CLASS FEATURE\n- This prompt lives or dies on LOD engineering: merged district meshes at far tier, instanced building archetypes with per-instance variation at mid tier, bespoke detailed blocks streaming in near the camera, imposters for the far tier of the opposite end of the island.\n- Traffic, boats and window lights are instanced systems with LOD behavior of their own.\n- Quality selector degrades far window variation, traffic density and reflections before ever degrading island completeness or landmark silhouettes.\n- Must remain smooth on a modern laptop through the entire zoom range; clamp devicePixelRatio to 2; no memory explosions. The wow is the whole island, alive, in one unbroken piece.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-02\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>02. Ancient Rome Voxel City Centre Simulation Spec\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\n#### OBJECTIVE\n\nCreate a breathtaking, high-definition voxel-art simulation of the entire Ancient Roman City Centre, anchored by a massive, detailed Colosseum. The scene must be generated procedurally, featuring topography, a dense cityscape, and intelligent layout planning.\n\n#### USER CONTROLS\n\n- **Camera:** \"God-mode\" orbit controls (Left-click rotate, Right-click pan, Scroll zoom).\n- **Shortcuts:**\n  - **[R]** Re-centre on Colosseum.\n  - **[F]** Flyover mode (constant rotation around the city).\n  - **[T]** Toggle Time of Day (Day\u002FSunset).\n\n#### WORLD GENERATION & GEOLOGY (Requirement: Solid & Natural)\n\n- **Topography:** Generate a terrain mesh representing the \"Seven Hills of Rome\" (rolling elevation changes) and the Tiber River cutting through the edge of the map.\n- **Solid Ground:** Ensure the floor is a continuous, solid voxel mesh (no gaps\u002Fvoids). Use varied palettes for the ground: cobblestone for streets, grassy banks for hills, and dirt for the arena floor.\n- **Vegetation:** Procedurally scatter Roman vegetation: Italian Cypress trees (tall\u002Fthin), Umbrella Pines (high canopy), and olive shrubs on the hillsides to frame the architecture.\n\n#### ARCHITECTURAL SCOPE (Requirement: High Definition & Variety)\n\n#### The Colosseum (Centerpiece)\n\n- High-resolution voxel scale (smaller voxels for finer detail).\n- **Internal details:** Cavea (seating tiers), the Hypogeum (exposed underground maze), and the Velarium (awning structure).\n- **Population:** Dense crowds (colored voxel clusters) and Gladiators battling in the center.\n\n#### The City Centre (The Forum & Surroundings)\n\n- Surrounding the Colosseum, generate a dense array of contemporary structures.\n- **Landmarks:** Include abstract representations of the Arch of Constantine, the Temple of Venus and Roma, and the Basilicas.\n- **Infrastructure:** Aqueducts spanning the horizon, colonnades, and a distant Circus Maximus track if render budget allows.\n- **Residential:** Dense insulae (apartment blocks) with terracotta roofs filling the gaps between major monuments.\n\n#### CITY PLANNING LOGIC (Requirement: No Overlap)\n\n- **Grid & Collision:** Implement a bounding-box allocation system. Before placing a building, check the grid to ensure no overlap with existing geometry.\n- **Zoning:**\n  - **Zone A (Center):** Colosseum (Fixed position).\n  - **Zone B (Forum):** High-density Temples and Basilicas.\n  - **Zone C (Outskirts):** Residential and Hills.\n- **Roads:** Generate clear \"Cardo\" and \"Decumanus\" style stone pathways connecting major buildings; buildings must snap to these paths.\n\n#### VISUAL FIDELITY\n\n- **Atmosphere:** Warm, Mediterranean lighting.\n- **Water:** The Tiber River must feature a reflective or semi-transparent blue voxel material.\n- **Palette:** Use a rich, historical palette: Travertine (creamy white), Porphyry (purple\u002Fred), Terracotta (orange\u002Fbrown), Marble (white\u002Fgrey), and Gold accents for temple roofs.\n- **Shadows:** Approximate ambient occlusion or directional lighting to give depth to the voxel blocks.\n\n#### TECHNICAL SPECIFICATIONS\n\n- **Deliverable:** Provide the full implementation.\n- **Offline only:** All code\u002Fassets embedded. NO external imports\u002FCDNs.\n- **Performance:** Target >= 55 FPS.\n- **Crucial:** Use InstancedMesh (Three.js concept or WebGL equivalent) for all voxels. Do NOT create individual geometry for every block. Merge geometries where possible.\n- Use a shared texture atlas generated programmatically (Canvas API) for voxel colors to reduce draw calls.\n\n#### IMPLEMENTATION GUARDRAILS\n\n- **Module Resolution:** Use `\u003Cscript type=\"importmap\">` for any Three.js logic, mapping `\"three\"` to a minified, base64-encoded inline version OR write raw WebGL2 if confident.\n- **Scope Safety:** Use const\u002Flet, avoid global namespace pollution.\n- **Memory:** Dispose of geometries\u002Fmaterials if regenerating.\n- **Code Quality:** Robust error handling. If a procedural placement fails 10 times, skip that building to prevent infinite loops.\n\n#### FINAL OUTPUT INSTRUCTION\n\nGenerate the full output now. Ensure the scale feels \"Grand\" and the resolution is high enough that the Colosseum looks curved rather than square.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-03\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>03. The Seven Wonders - One Horizon\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate a maximum-ambition Three.js world in which all Seven Wonders of the Ancient World stand together, restored and alive, along one continuous sunlit coastline - an image that has never existed and can only exist here. The camera sails a grand bay: the Lighthouse of Alexandria guards the harbor mouth; the Colossus of Rhodes stands over the next inlet; the Great Pyramid of Giza rises inland on a golden plain; the Hanging Gardens of Babylon terrace down to the water in cascading green; the Temple of Artemis gleams in its precinct; the Statue of Zeus is glimpsed enthroned through the doors of its own temple; and the Mausoleum at Halicarnassus crowns a headland. This must not be a museum of scattered models on flat ground, a diorama with toy scale, or a dark stylized montage. It is one coherent, breathing ancient Mediterranean world at true relative scale.\n\nThe goal is the visual impression of a billion individually considered pieces: column flutes, gilded statues, painted friezes, terraced plantings, harbor chains, rigging, roof tiles, market awnings, processional roads and thousands of inhabitants. Achieve it with extreme visible detail, instancing and nested LOD, not raw counts.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Everything procedural; no external assets.\n\n#### FIRST FRAME - SEVEN WONDERS, ONE HORIZON\n- Open from the deck-height of a ship entering the bay in late-morning sun: the Pharos towering close on one side with its smoke and mirror flashing, the Colossus visible across the water, and at least four other wonders readable along the receding coastline, each unmistakable by silhouette alone.\n- The bay is alive: merchant ships under sail, oared galleys, fishing boats, gulls, sparkling water and wakes. The shore is alive: harbors, warehouses, processions, caravans moving between the wonders on a coastal road.\n- True relative scale is a core spectacle: the Pyramid must dwarf everything as a mountain of geometry; the Pharos and Colossus read as astonishing but human-made; the temples are vast yet approachable. The viewer should visibly FEEL the size ranking.\n- Bright Mediterranean light, saturated sea, painted architecture. No menus, titles or reveals.\n\n#### EACH WONDER, DONE JUSTICE\n- Pharos of Alexandria: three tapering tiers, the flame chamber with a polished mirror flashing periodically, spiral ramp traffic of fuel donkeys, statues at the corners, waves breaking on its mole.\n- Colossus of Rhodes: a bronze sun-god standing beside (not straddling) the harbor entrance on a great pedestal, sun blazing off the bronze, ships passing beneath his gaze, a radiate crown catching light.\n- Great Pyramid of Giza: polished white casing intact with a gilded capstone, mirror-flat faces flashing the sun, a processional causeway, sphinx and satellite pyramids suggested, heat shimmer on the plain.\n- Hanging Gardens of Babylon: stepped terraces overflowing with instanced vegetation, visible water-lifting screws and channels glinting as they turn, waterfalls between levels, gardeners moving among palms.\n- Temple of Artemis: a forest of slender columns with painted capitals, votive smoke, pilgrims, market of silver trinkets at its steps.\n- Statue of Zeus at Olympia: inside its temple with the great doors open toward the sea road, the seated god in gold and ivory glimpsed glowing in shadowed interior light - a composed reveal through columns that rewards approaching the doorway.\n- Mausoleum at Halicarnassus: the stepped roof and chariot finial on its headland, sculpted friezes readable up close, cypress avenue approaching.\n\n#### ONE WORLD, NOT SEVEN EXHIBITS\n- Stitch the wonders with living connective tissue: a coastal road carrying caravans of camels and carts, way-stations, aqueduct fragments, fishing villages, olive groves and vineyards on the slopes, herds, and a shared sea full of traffic moving between harbors.\n- Each wonder generates its own activity system: pilgrim queues at Artemis and Zeus, construction-free (all complete and maintained - crews polish and garden rather than build), harbor loading at Pharos and Rhodes, funerary procession at the Mausoleum, priests on the Gardens' terraces.\n- Populations are autonomous and purposeful: walking, sailing, loading, worshipping, trading. No frozen mannequins.\n\n#### LIGHT, MATERIAL AND DYNAMISM\n- Materials carry the spectacle: blinding white marble, painted friezes in ochre, blue and red, gilded bronze, polished limestone casing, deep green terraces, turquoise shallows over sand.\n- The sun's low-morning angle rakes everything; the Pharos mirror and Pyramid faces throw periodic flashes; the Colossus burns like a candle at certain camera angles - stage these alignments deliberately.\n- Constant gentle dynamism: sails filling, waterwheels and screws turning, smoke columns, banners, birds, waves and wakes, cloth awnings breathing.\n\n#### EXPLORATION AND CONTROLS\n- Default experience: a slow, majestic sail-by camera path along the whole coast that the viewer can pause, scrub and detach from at any moment into free orbit; a reset returns to the ship's-deck hero start.\n- Presets: one perfect composition per wonder plus the full-coast aerial that shows all seven at once - the impossible postcard.\n- Compact controls: time of light (morning \u002F golden evening \u002F torch-lit dusk with the Pharos flame dominant), sea and land activity density, sail-by speed, photo mode.\n\n#### PERFORMANCE\n- Bespoke maximum detail on whichever wonder is nearest the camera, streaming detail budgets as the sail-by progresses; silhouette-perfect distant wonders at all times - the seven must NEVER pop or vanish.\n- Instanced vegetation, crowds, ships, columns and friezes; merged terrain and far architecture; LOD tuned so the full-coast view stays crisp.\n- Quality selector reduces crowd density, vegetation and reflections before ever sacrificing wonder silhouettes or material splendor.\n- Smooth on a modern laptop, devicePixelRatio clamped to 2. The outcome: the greatest hits of the ancient world, finally in one frame, alive.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-04\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>04. One Riverbank, Two Thousand Years\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate a maximum-ambition Three.js experience of one fixed stretch of the Thames riverbank in London, watched from the same camera position across two thousand years, driven by one grand time slider. Every position of the slider is a complete, living, richly detailed world; dragging it morphs the city through history: Roman Londinium's timber wharf, the medieval city crammed onto Old London Bridge, the Great Fire glowing at night, the Victorian forest of masts and steam, the Blitz's searchlights, and today's glass skyline. This must not be a slideshow of static dioramas, a fade between five images, or a sparse stage set. It is one continuous place breathing across centuries, with the river as the only constant.\n\nThe goal is the visual impression of a billion individually considered pieces in EVERY era: timber joints, rigging, brick chimneys, market stalls, cranes, buses, and thousands of inhabitants living each period. Achieve it with instancing, era-streaming and nested LOD, not raw counts.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Everything procedural; no external assets.\n\n#### FIRST FRAME - TODAY, THEN THE SLIDER\n- Open on the present day, fully alive: the river bend with a recognizable modern composition (a great bridge, the dome of St Paul's holding its ancient ground among glass towers), boats, buses, crowds on the embankment, afternoon light on the water.\n- The time slider is immediately visible as an elegant timeline along the bottom, marked with era labels and small icons. It is the single hero control and invites dragging within seconds.\n- No menus, titles or reveals; the present-day world must already reward exploration before the slider is touched.\n\n#### THE ERAS - SIX COMPLETE WORLDS\n- Roman, around AD 100: timber quay and warehouses, a bridge of boats or early timber bridge, red-roofed bathhouse and forum on the low hill, galleys unloading amphorae, legionaries, mud, smoke, geese.\n- Medieval, around 1400: Old London Bridge crowded with tall houses and its chapel, water wheels roaring between the piers, church spires beyond, timber-framed riverfront, ferrymen, markets, laundry, pigs in lanes.\n- The Great Fire, September 1666, night: the city alight upriver, a wall of orange glow and sparks against the dark, silhouetted fleeing boats loaded with belongings, firelight dancing on the water, St Paul's (old, gothic) burning on the skyline. Terrifying and beautiful, but rendered bright and readable, never murky.\n- Victorian, around 1850: a forest of masts and steam funnels, warehouses with cranes swinging cargo, the new stone bridges, horse traffic, gaslights, coal smoke haze golden in low sun, mudlarks on the foreshore.\n- The Blitz, 1940, night: searchlight beams sweeping, barrage balloons silver overhead, the skyline dark except for fire glows and the famous silhouette of St Paul's dome standing amid smoke, tracer arcs distant, river reflecting it all. Handle with grandeur and restraint - no gore, the drama is light and survival.\n- Today: the same bend with its modern icons, tour boats, joggers, buskers, glass towers, the surviving old buildings visibly the same structures the viewer watched exist in earlier eras.\n\n#### CONTINUITY IS THE MAGIC\n- Anchor objects must persist and visibly evolve so the morphing feels like one place aging: the river bend and foreshore; one church that grows from stone chapel to gothic spire to Wren dome; one street line that never moves; a corner tavern that is a Roman inn, a medieval alehouse, a Victorian pub and a modern pub with the same footprint.\n- When the slider moves, buildings must not simply crossfade: they grow, are re-clad, burn, are rebuilt - staged as fast, readable transformations with scaffolding-free elegance (rising from footprints, roofs assembling, styles re-skinning) so scrubbing back and forth is itself a spectacle.\n- The river always flows; boats of the correct era always move on it; birds persist across all time.\n\n#### EVERY ERA FULLY ALIVE\n- Each era carries its own autonomous population with correct dress, vehicles and routines: unloading, trading, fleeing, promenading, commuting. Density comparable to the best living-city scenes, never a sparse stage.\n- Each era has signature motion: Roman oars and cranes, medieval water wheels, 1666 flames and ember drift, Victorian steam and swinging cargo, Blitz searchlights and balloons, modern traffic and rowing eights.\n- Sound-free visual storytelling: readable vignettes in every era rewarding zoom (a Roman merchant arguing over an amphora, a 1666 family loading a boat with a birdcage, a Victorian crane lowering a piano, a modern couple photographing the same view the viewer occupies).\n\n#### LIGHT AND MATERIAL\n- Each era gets a distinct, gorgeous lighting signature as listed above; transitions in time also transition light smoothly (scrubbing from 1850 afternoon into 1940 night is a cinematic event).\n- Materials evolve honestly: timber, wattle, stone, brick, iron, concrete, glass - weathered and believable at close range in every period.\n\n#### EXPLORATION AND CONTROLS\n- The camera holds one privileged bankside position by default but supports orbit, pan and zoom within a generous bubble, plus presets: foreshore level, bridge level, rooftop level, and a high aerial that makes each era's full extent readable.\n- The time slider supports both snapping to era labels and free scrubbing between them with interpolated transformation states.\n- Compact secondary controls only: activity density, a small \"era facts\" toggle OFF by default, photo mode.\n\n#### PERFORMANCE\n- Stream era content intelligently: the active era at full fidelity, adjacent eras pre-warmed for instant scrubbing, distant eras unloaded; shared geology, river and anchor objects always resident.\n- Instanced crowds, boats, buildings and props per era; merged distant skylines; LOD discipline throughout.\n- Quality selector reduces population and far detail before ever sacrificing transformation smoothness or era completeness.\n- Smooth on a modern laptop, devicePixelRatio clamped to 2.

This must not be an isolated tower, a sparse diorama, a generic skyline, an arcade challenge or a simple postcard with a few props. It is a complete Paris landmark environment whose craftsmanship makes the viewer immediately stop and inspect it.\n\nThe goal is the visual impression of a billion individually considered pieces: lattice members, rivets, stairways, elevator machinery, lamps, balustrades, roof dormers, paving stones, trimmed hedges, cafe tables, boats, figures, street furniture, flowers, reflections and moving life. Achieve this through extreme visible detail, intelligent instancing, merged geometry, procedural variation and distance-aware density, not by creating an unusable literal billion draw calls. Make every close camera position reveal new workmanship while the hero view stays clean, iconic and instantly understandable in a fraction of a second.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Generate geometry, materials, textures, lighting, people, water, vehicles, foliage and animation procedurally; do not rely on external image assets or downloaded models. A finely crafted micro-block or micro-voxel construction language is welcome for buildings, foliage, paving and structural embellishment, provided the tower remains faithful, elegant and unmistakably wrought iron rather than a chunky toy silhouette.\n\n#### FIRST FRAME - PARIS IN ONE ASTONISHING IMAGE\n- Open directly on the completed masterpiece. No title screen, introduction, camera flight, construction animation, loading theatre, menu, empty ground plane or delayed reveal.\n- Default to an elevated, carefully composed Trocadero-side three-quarter vista aligned across active fountains and the Seine toward the Eiffel Tower, with the full height of the tower dominant and enough Champ de Mars, riverfront and Paris roofscape visible to make the environment feel vast.\n- The tower must consume the viewer's attention immediately, yet the frame must be almost unbelievably full: fountain spray sparkling in sunlight, Pont d'Iena traffic and pedestrians, bateaux on the river, tree canopies and paths, crowds as small scale cues, garden beds, distant limestone roofs and a bright Paris sky.\n- Use a luminous late-spring afternoon just after a brief rain shower: wet stone catches highlights, fresh trees glow, water carries broken reflections and air clarity lets the structural precision read. Keep it bright, colorful and inviting, never murky or dominated by darkness.\n- The scene must read as real Paris before the viewer interacts, without large text labels or explanatory panels.\n\n#### THE EIFFEL TOWER - ENGINEERING AS JEWELRY\n- Construct the complete tower with extraordinary structural hierarchy: four vast curved piers; crossing iron lattice at multiple scales; arches between legs; platform floors; railings; stairs; elevator tracks and cabins; observation decks; restaurants suggested behind glazing; antenna assemblies; beacon and small maintenance details.\n- At hero distance, the silhouette and elegant taper must be perfect. At close range, expose densely layered ironwork, secondary beams, gusset plates, rivet patterns, mesh railings, stair landings, lift machinery housings, warning lamps, cables, glazing, tiny visitor silhouettes on platforms and warm paint variation on sun-facing versus shaded members.\n- Make the base monumental and inhabitable: stone footings, ticket and security structures kept visually discreet, queues and visitors flowing beneath the legs, path barriers, benches, souvenir kiosks, shaded planting, maintenance access, elevator movement and shadows cast by the iron lattice across the ground.\n- Light must travel through the structure: thousands of patterned shadows on grass and paving, sun glints moving over beams, atmospheric depth through layers of trusswork and subtle occlusion that makes it feel assembled rather than extruded.\n- Never replace fidelity with abstract lines or a simplistic low-poly cone. From any close preset the landmark must reward examination.\n\n#### THE COMPLETE AXIAL PARIS ENVIRONMENT\n- Build the entire readable landmark axis as part of the subject: Trocadero terrace and descending gardens in the foreground, the active Warsaw-style fountain basin and jets, Pont d'Iena across the Seine, quay walls and riverside paths, Eiffel Tower on the Champ de Mars, the long lawns and tree avenues receding toward the Ecole Militaire direction.\n- Create the Seine as a genuine moving layer of the environment: rippling green-blue water, sun sparkles, reflections of tower legs and bridge arches, tour boats and smaller craft with wakes, quay steps, mooring rings, riverside pedestrians, cyclists and shaded trees.\n- Fill the Champ de Mars with refined life rather than visual clutter: clipped lawns, gravel paths, flowerbeds, symmetrical tree rows, families, photographers, picnics, joggers, gardeners, a few pigeons only where natural, benches, lamps and the subtle seasonal variation of leaves and blossoms.\n- Beyond the immediate gardens, generate a rich Paris envelope: cream stone apartment blocks with mansard roofs, chimneys, dormer windows, balconies, awnings, cafe corners, road lanes, parked vehicles, moving buses and taxis, street trees, lampposts and distant skyline layers that fade correctly into haze.\n- Nothing important may float on blank ground or stop at an abrupt edge. Use landscaped transitions, city blocks, river bends and atmospheric distance to make this feel like a complete place.\n\n#### COUNTLESS SMALL STORIES ALREADY ALIVE\n- The completed environment should be peacefully busy from first frame: fountains already dancing, elevators already climbing inside the tower, boats already passing beneath the bridge, pedestrians crossing, traffic moving, trees rustling and photographers turning toward the view.\n- Stage readable human moments at different scales: a proposal photo being framed on the terrace, children at a fountain edge, a painter with an easel, a waiter setting cafe chairs near a side street, a riverboat upper deck of waving passengers, visitors pointing upward from beneath the tower and maintenance staff quietly checking a planted bed.\n- Build people and vehicles as detailed but efficient stylized figures whose color and pose give scale and warmth without stealing focus from the landmark.\n- Add fine atmospheric animation: fountain mist catching miniature rainbow fragments, wet leaves releasing droplets, flags shifting, boat wake reflections rolling across quay stone, elevator lights sliding upward and cloud shadows passing slowly over the lawn.\n- Avoid spectacle that replaces the place: no fireworks, ring courses, giant fantasy additions, collapsing architecture or game objective. The shock is the reality and density of the living world itself.\n\n#### MATERIALS, LIGHT AND MICRO-FIDELITY\n- Use physically persuasive material contrast: painted iron with subtle roughness and warm brown variation; pale limestone buildings; wet gray-beige paving; transparent fountain spray; deep river water; waxy spring leaves; glass boat canopies; polished vehicle paint; metal railings and small golden lamps.\n- Create procedural micro-texture where the camera can approach: paving seams and damp patches, garden gravel, bark, roof tile rhythms, balcony iron curls, window interior glow, river wall masonry, cobbled service routes, road markings and cafe terrace patterns.\n- Use high-quality shadows, ambient occlusion cues, contact shadows and restrained bloom only for sun glints and small reflective accents. Avoid hazy over-bloom that erases lattice detail.\n- Reflections must tell the story: distorted tower fragments in the Seine, fountains on wet paving, moving boats breaking reflected beams, glass observation decks catching sky and vehicles sliding through damp road highlights.\n\n#### EXPLORATION THAT REVEALS CRAFT, NEVER HIDES IT\n- Orbit, pan and zoom must function immediately, with a single reset returning to the spectacular full-axis hero composition.\n- Include beautifully tuned camera presets: Trocadero full vista; low fountain-edge view through spray; riverside view with boat and reflected tower; beneath-the-iron-leg engineering close-up; observation platform looking down the Champ de Mars axis; overhead district model view showing gardens, river and surrounding blocks.\n- Keep collision and near-plane behavior comfortable around structural geometry; allow close inspection without camera trapping inside the lattice.\n- Meaningful compact controls only: daylight state (rain-cleared afternoon \u002F golden sunset \u002F sparkling blue hour), environment density (serene \u002F lively \u002F grand Paris day), fountain and river activity, and a structural detail spotlight toggle that gently emphasizes tower engineering without changing the scene into an infographic.\n- UI must be small, elegant and collapsible, leaving the first frame almost entirely to Paris.\n\n#### EXTREME DETAIL WITH DISCIPLINED PERFORMANCE\n- Allocate bespoke maximum detail to the tower, closest fountain terraces, bridge, first river boats, near crowds and hero garden paths; every preset must have an obvious high-fidelity focal region.\n- Use nested levels of detail: genuine fine tower geometry near the camera, simplified but silhouette-perfect structural layers at distance; dense instance fields for trees, figures, roof details, paving, lights, benches and vehicles; merged static city blocks beyond the primary vista.\n- Use instanced animated systems for crowds, traffic, boats, fountain droplets, tree leaf clusters and distant window variation. Preserve the impression of limitless pieces while keeping draw calls rational.\n- Provide a quality selector that preserves composition and landmark detail first: reduce far roof ornament, crowd count, foliage density and reflection sampling before sacrificing the tower's lattice, fountain hero layer or river reflections.\n- Target a smooth interactive experience on a modern laptop, clamp devicePixelRatio to 2, pause expensive offscreen work and avoid memory explosions. The desired outcome is not a benchmark failure; it is the most overwhelmingly detailed Eiffel Tower world that remains pleasurable to explore.\n\n#### LIVING WORLD SIMULATION - PARIS WITH PURPOSE\nThis is not a populated still-life. From the opening frame it must feel like an actual Paris afternoon continuing whether or not the viewer moves the camera. Use many lightweight autonomous agents with destinations, timing, state changes and visible interactions; do not scatter stationary crowd blobs around the landmark.\n- Give visitors readable routines: couples enter the Trocadero overlook, pause for photographs, descend toward the fountains; families cross paths and settle briefly on lawns; tower visitors queue, advance beneath a leg and reappear as silhouettes on elevator decks. Photographers turn, frame a shot, then move aside rather than looping one idle pose.\n- Make transport a connected flow system: buses and taxis follow lanes, slow at crossings, stop behind signals and continue; cyclists overtake on riverside paths; tour boats approach, pass beneath Pont d'Iena, throw wakes against the quay and carry seated or standing passenger silhouettes.\n- Let agents affect the world: pedestrians avoid each other and pause at curb edges, fountain-edge children create small splash\u002Fripple events, boats deform reflected water, elevator cabins rise on staggered schedules and gardeners move between planted beds with tools.\n- Vary cadence and intent visibly: strolling, hurrying, queuing, resting, looking upward, photographing, boarding and crossing should form small believable stories across foreground, bridge, lawn and tower base.\nImplement motion efficiently with instanced\u002Fstateful agent pools, path networks, simple avoidance and LOD. Preserve meaningful autonomous activity even at the calmest density setting; never replace life with identical walking loops, random jitter, frozen silhouettes or decorative dots.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-06\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>06.

Prioritize a believable atmosphere\u002Fsky, water, and traffic flow.\n\nUSER CONTROLS\n- Fog bank slider: 0 → 100%\n  - Controls a **height-based fog bank** that lives mostly under and around the deck.\n  - At 100% it should be unmistakably foggy around the bridge and water surface (even in Clear weather), rising and falling as a coherent bank, not just a global haze.\n- Traffic density slider: 0 → 100%\n  - Controls the number of vehicles on the roadway and approaches.\n  - Vehicles drive continuously and loop seamlessly so traffic feels endless.\n- Water waves slider: 0 → 100%\n  - Controls how wavy\u002Fchoppy the bay looks (wave height, choppiness, and whitewater\u002Ffoam presence).\n  - At 0% water is calmer (gentle ripples). At 100% (especially in Stormy) it should look close to storm conditions, not just a subtle height shift.\n- Weather selector: presets (Clear, Marine layer, Overcast, Stormy)\n  - Each preset should be **meaningfully different**, not minor tweaks.\n  - Clouds should be visible and animated (layered drift), with cloud height\u002Fopacity responding to the active preset.\n  - Clear: vibrant, believable blue sky; crisp visibility; minimal cloud cover.\n  - Marine layer: a low fog bank\u002Fhaze sitting near the water\u002Funder the deck; cooler lighting.\n  - Overcast: heavy cloud cover with diffuse lighting; muted contrast but still clearly visible (not “can’t see anything”).\n  - Stormy: dark clouds, rain, lightning; stronger waves; dramatic but still readable (not pure black or an overly aggressive rectangular haze layer). Lightning should briefly illuminate the scene\u002Fwater.\n  - Rain should be visibly present and make surfaces look wet (road\u002Fbridge sheen, occasional puddling).\n- Time of day slider: Morning → Night\n  - Drives sun\u002Fmoon position, sky color, exposure, water color, stars, and intensities for night-time lights (deck lights, vehicle lights, skyline, Alcatraz).\n  - Sunrise\u002Fsunset should be clearly visible and “golden hour” should feel distinct from midday.\n- Comet button (available at night)\n  - Pressing the button sends a visible comet across the sky **above the bridge**, traveling roughly perpendicular to the bridge’s span.\n  - The comet should have a believable head + glowing tail (golden tint), without hard-edged halos.\n  - It should briefly light up the environment in an impressive way and produce a visible reflection\u002Fresponse on the water.\n- Whales button\n  - Pressing the button spawns **1–5 humpback whales** in the bay (randomized count), behaving as a loose group.\n  - Whales should look recognizable (not like submarines) and do typical behaviors: swimming, surfacing, breaching\u002Ftail slaps, etc.\n  - They must stay in the water, avoid land, and avoid intersecting the bridge\u002Fstructures.\n  - Their motion should produce visible water interaction: ripples, spray\u002Fsplashes, and disturbance that reads with the current wave conditions.\n- Camera: Free orbit \u002F pan \u002F dolly (OrbitControls-style).\n- UI readout: show current values for fog %, traffic %, waves %, whales count, and a time-of-day label.\n\nSCENE CONTENT & BACKGROUND\n- Golden Gate Bridge\n  - Two Art Deco towers, suspension cables, and vertical hangers in correct “International Orange”.\n  - Suspension system must read as structurally connected:\n    - Main cables attach at tower tops and continue to both ends (anchorages), not terminating mid-air.\n    - Vertical hangers run continuously from main cables down to the deck along the main span.\n  - Bridge shape should be coherent and believable:\n    - Towers are not floating; they connect to believable bases\u002Ffootings at water\u002Fland.\n    - Road deck and side edges\u002Fcatwalk elements connect cleanly to approaches (no mismatched “edgy” shapes where a rounded\u002Fcircular edge is expected).\n- Roadway and traffic\n  - Roadway on top of the deck plus approach roads on both sides with lane markings.\n  - Approach roads should extend far enough that the visible road doesn’t end abruptly near the bridge (traffic should disappear off-screen naturally).\n  - Multi-lane traffic in both directions:\n    - Mix of cars and heavier vehicles (trucks\u002Fbuses), with **10+ visually distinct vehicle archetypes** and realistic scale variation.\n    - Vehicle colors must be varied and realistic (traditional automotive palette; avoid toy-like saturation; avoid “all grey”).\n    - Vehicles must not overlap\u002Fclip through each other; maintain believable spacing so both directions read correctly.\n    - Headlights\u002Ftaillights are emissive and brighten as it gets darker.\n- Terrain and shoreline\n  - Natural terrain for Presidio (south) and Marin (north): rolling hills framing the bridge down to shoreline.\n  - Vegetation shading: deeper greens near water, pushing into slightly dry\u002Fgolden tones at higher elevations; avoid neon\u002Fflat greens.\n  - Shoreline should look **natural**, not like a square cutout; land should extend to the edges of the simulation so the world doesn’t feel like a clipped rectangle.\n  - Ensure water\u002Fshore interaction doesn’t flicker at shallow areas (no “z-fighting” look).\n- San Francisco skyline (distant silhouette) on the Presidio side\n  - Simple skyline silhouette with soft window\u002Femissive detail that becomes more noticeable at night.\n  - Night emissives should feel plausible (not overly harsh\u002Fglowy).\n- Alcatraz hint\n  - Small island with rocky base, a main prison block mass, and a simple tower\u002Flighthouse element with subtle emissive at night.\n- Bay water\n  - Visually impressive water that avoids obvious tiling\u002Fsquare artifacts.\n  - Multi-scale wave motion with foam\u002Fwhitewater accents, especially at higher wave settings and stormy weather.\n  - Reflects sun\u002Fmoon and overall sky color in a believable, non-blinding way (avoid “white-out” reflections at midday).\n  - Integrates with fog and weather (fog bank sits on\u002Fover it; stormy rain affects its look).\n- Vessels\n  - Several varied boats\u002Fships (not just rectangles) such as cargo\u002Fcontainer ships, tankers, and a ferry.\n  - Ships should follow **purposeful routes** (e.g., recognizable shipping lanes \u002F ferry route), not aimless drifting, and move independently with distinct speeds\u002Fphases.\n  - Ships remain in the water and do not intersect land\u002Fbridge; light bobbing\u002Fwake is a plus if it reads well.\n- Additional environment detail\n  - Instanced trees placed on hillsides (no floating trees, none in water).\n  - Small flock of birds circling\u002Fgliding near\u002Faround the bridge.\n  - Distant background\u002Fbowl geometry to close the horizon.\n- Sky, Sun, Moon, Stars\n  - Day sky must be clearly **blue** in Clear weather, with a natural horizon haze gradient (not pale grey\u002Fwhite).\n  - The sun should be visible as a disc\u002Fbright element when above the horizon, not just an overexposed white screen.\n  - Morning vs midday vs afternoon should feel different; sunrise\u002Fsunset should be clearly warmer and more dramatic.\n  - Night sky should be dark but not empty: visible moon and a tasteful starfield (stars present and noticeable, but not overly dense).\n  - Stars fade in\u002Fout smoothly during the day→night transition.\n\nTECHNICAL SPECIFICATIONS\n- Create a Self-contained output that runs in a blank Chrome tab with no bundler\u002Fbuild step.\n- Use Three.js as ES modules only:\n  - Include an import map (before the module script) mapping `\"three\"` and `\"three\u002Faddons\u002F\"` to the same pinned Three.js version.\n  - Import only via those names (no other bare specifiers).\n- Performance:\n  - Use instanced meshes for repeated objects (cars, trees, skyline windows\u002Fbuildings, etc.) and avoid unnecessary per-frame allocations.\n- Code quality:\n  - Never reuse identifiers in the same scope or shadow variables; prefer descriptive names.\n- Rendering:\n  - Physically plausible lighting setup (sun\u002Fmoon directional, hemisphere\u002Fambient fill as appropriate).\n  - ACES-Filmic tone mapping and sRGB output.\n  - Avoid deprecated Three.js settings and avoid any console errors\u002Fwarnings (e.g., shader compile errors, WebGL feedback loop errors).\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-07\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>07. Billion-Piece Istanbul - Hagia Sophia and the Golden Horn\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate an unprecedented, museum-quality Three.js environment of Istanbul's historic peninsula and the Golden Horn at golden hour: Hagia Sophia and the Blue Mosque crowning the skyline, the Galata Bridge alive with fishermen and traffic, ferries crossing glittering water, gulls wheeling through warm light, and the layered city rising on both shores. This must not be a single isolated mosque, a sparse waterfront, a generic Middle-Eastern skyline or a postcard with three props. It is the complete living panorama of one of the greatest city views on Earth.\n\nThe goal is the visual impression of a billion individually considered pieces: domes and semi-domes, minaret balconies, lead roof seams, courtyard arcades, bazaar awnings, rooftop terraces, chimneys, satellite dishes, ferry railings, fishing rods, mooring bollards, cobbles, cypress trees, and thousands of windows catching the sun. Achieve this with extreme visible detail, intelligent instancing, merged geometry and distance-aware density rather than unusable raw geometry.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Generate everything procedurally; no external assets.\n\n#### FIRST FRAME - THE IMPERIAL SKYLINE IN GOLD\n- Open directly on the completed masterpiece: a view from above the Galata side looking across the Golden Horn toward the historic peninsula, Hagia Sophia and the Blue Mosque silhouetted against warm late-afternoon light, the water between filled with moving ferries and their wakes.\n- The frame must be spectacularly full: the Galata Bridge with its double deck of traffic above and restaurants below, dozens of fishermen with lines in the water, white ferries with red trim crossing in both directions, gulls circling and diving, domes and minarets stacked up the hill, and the dense texture of the city rolling away in every direction.\n- Light is the soul: low golden sun raking across lead domes, glinting off windows on the Asian shore, scattering in ferry wakes, and warming the limestone and brick of the old city. Bright, warm and inviting; never murky.\n- No labels, menus or introductions. It must read as Istanbul within one second.\n\n#### THE MONUMENTS - CROWNS OF THE PENINSULA\n- Build Hagia Sophia with true structural character: the great central dome with its ring of windows, cascading semi-domes, massive buttresses, four minarets of differing character, pink-toned masonry, and courtyard trees. At distance the silhouette must be perfect; up close, window grilles, lead roof panels, cornice detail and weathering must reward inspection.\n- Build the Blue Mosque as its counterpart: the nested cascade of domes, six slender minarets with multiple balconies, the arcaded courtyard, and its cooler grey-blue tone against Hagia Sophia's warmth.\n- Support them with the honest fabric of Sultanahmet: Topkapi's walls and pavilion roofs among trees on the point, the Basilica Cistern's ventilation domes hinted in the ground plane, tram lines, fountains, plane trees, and the descending terraces of houses, hotels and shops down to the water.\n\n#### THE GOLDEN HORN AND THE BRIDGE\n- The water is a primary character: a broad, living surface with sun glitter, crossing ferry wakes that interact, current texture, reflected minarets breaking in the chop, and moored boats rocking gently.\n- The Galata Bridge must be fully alive: instanced fishermen with individual rods and occasional catches, strolling pedestrians, the tram crossing, cars and taxis, and the under-deck restaurant level with tables, lanterns and waiters visible between arches.\n- Ferry traffic runs as a genuine system: vessels departing Eminonu and Karakoy piers, swinging wide, passing each other with correct wakes, docking with reversing churn, passengers visible on decks. Add water taxis, a fishing boat or two trailing gulls, and simit sellers with red carts on the quays.\n- Gulls are a signature layer: flocks wheeling around minarets, following ferries, landing on bridge railings, individually animated with banking turns and glides catching the light.\n\n#### THE CITY FABRIC - TEXTURE WITHOUT END\n- Fill both shores with dense, varied, honest city: Ottoman timber houses, mid-rise apartment blocks with balconies and laundry, mosque after smaller mosque, the Galata Tower rising on its hill, the spice bazaar roofline, hans and workshops, rooftop terraces with tea tables, cypress and plane trees, and streets that visibly carry traffic and pedestrians up the slopes.\n- Distant layers must recede correctly into warm haze: the Bosphorus opening to the right with a suspension bridge hinted far away, the Asian shore glittering, ship traffic at anchor.\n- Nothing may stop at an abrupt edge; the city dissolves into atmospheric distance in every direction.\n\n#### COUNTLESS SMALL STORIES ALREADY ALIVE\n- Stage readable human moments: a fisherman lifting a flashing catch, a ferry passenger throwing bread to gulls mid-crossing, tea being carried on a swinging tray across the bridge, a wedding photo on a terrace, kids racing down steps toward the quay, a cat sunning on a warm wall (this is Istanbul; include its cats).\n- All agents are autonomous with destinations and routines: ferries on schedules, fishermen recasting, walkers with intent, gull flocks reacting to ferries and food.\n- Fine atmospheric animation everywhere: flags, awnings, laundry, steam from tea urns, shimmering sun path on water, slow cloud shadows crossing the hills.\n\n#### EXPLORATION AND CONTROLS\n- Orbit, pan and zoom immediately; a single reset returns to the golden hero panorama.\n- Camera presets: the classic Galata-side panorama; bridge deck among the fishermen; ferry bow mid-crossing with gulls; Sultanahmet terrace between the two great mosques; high aerial showing the Horn, the point and the Bosphorus junction.\n- Compact controls only: time of light (golden hour \u002F soft morning \u002F blue evening with lit minarets), water traffic density, gull density, and a photo mode hiding UI.\n\n#### EXTREME DETAIL WITH DISCIPLINED PERFORMANCE\n- Bespoke maximum detail on Hagia Sophia, the Blue Mosque, the bridge and the nearest ferries; every preset has an obvious high-fidelity focal region.\n- Nested LOD everywhere: full monument geometry near camera, silhouette-perfect distant structures, instanced windows, roof tiles, figures, gulls, boats and trees, merged far hillsides.\n- Quality selector reduces far city ornament, crowd and gull counts and reflection sampling before ever sacrificing monument fidelity or water life.\n- Smooth on a modern laptop, devicePixelRatio clamped to 2, memory rational. The outcome: the definitive living Istanbul panorama.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-08\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>08. Billion-Piece Harbin - The Glowing City of Ice\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate a maximum-ambition Three.js environment of the Harbin Ice and Snow World at blue hour: an entire city of palaces, towers, bridges, and colonnades built from translucent ice blocks, every structure glowing from within by embedded colored light, under a deep indigo winter sky. This must not be a single ice sculpture, a sparse plaza with a few glowing boxes, a daytime scene, or a murky night render. It is a complete luminous ice metropolis whose scale and inner light make the viewer stop immediately.\n\nThe goal is the visual impression of a billion individually stacked ice blocks: walls with visible block courses, frozen mortar seams, staircases, battlements, arched gates, spiral towers, an ice Ferris-wheel silhouette, long slide chutes with riders, lantern rows, and carved statues, all reading as real cut ice rather than tinted glass boxes. Achieve this through extreme visible detail, intelligent instancing, merged geometry and distance-aware density, not literal unusable geometry counts.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Generate all geometry, materials, lighting, people and snow procedurally; no external images or models.\n\n#### FIRST FRAME - A CITY OF LIGHT MADE OF ICE\n- Open directly on the completed masterpiece: an elevated three-quarter vista down the central boulevard of the ice city, the tallest glowing ice tower dominant, ranks of lit palaces receding into frosted haze on both sides.\n- The sky is deep blue dusk, not black: enough ambient cold light to read silhouettes, with the city itself supplying most illumination in saturated bands of aquamarine, magenta, amber and emerald glowing through the ice.\n- The frame must be almost unbelievably full: crowds in thick winter coats moving along swept paths, breath fog rising, children on ice slides mid-descent, food-stall steam, string lights, flag lines, distant frozen river and city glow on the horizon.\n- No title screens, menus, loading theatre, camera flights or delayed reveals. The city is simply there, complete and alive.\n\n#### ICE AS THE HERO MATERIAL\n- Ice must read as genuine cut river ice: translucent with visible internal depth, air bubbles and fracture planes suspended inside blocks, frost bloom on surfaces, sharp specular glints on edges, and colored light scattering through thickness so towers glow brighter at their cores and softer at their skins.\n- Build a believable subsurface-glow model: embedded light sources inside walls create gradients across block courses; adjacent blocks vary subtly in clarity and tint; thin elements like balustrades transmit more light than massive bases.\n- Snow must be its own material family: dry squeaky path snow with footprint texture, powder banks with sparkle glints, drifted roof caps, and slow light snowfall catching every colored light source.\n- Never let ice become flat emissive plastic. Every close approach should reveal block seams, tool marks, drip icicles, refrozen melt ripples and frost crystals.\n\n#### THE COMPLETE ICE METROPOLIS\n- Build a full district, not one building: a grand central palace with towers and curtain walls, an ice pagoda, a cathedral-like colonnade, triumphal gates, at least one long multi-lane ice slide with continuous riders, bridges over a frozen channel, a sculpture garden of carved translucent figures, lantern-lined boulevards and a plaza with a lit ice maze.\n- Surround the core with supporting life: ticket gates, warm-lit food stalls with rising steam, vendors, benches, snow-clearing crews, parked snow groomers, flagpoles, and the frozen Songhua river plane stretching behind the city with distant Harbin city lights.\n- Nothing floats on empty black ground. Paths, snowbanks, ice channel, river and horizon glow must form a complete, inhabitable winter world.\n\n#### A CROWD THAT BELONGS TO -30 DEGREES\n- Populate generously with instanced, individually varied visitors in bright padded coats, fur hoods and scarves: strolling couples, photo-takers, queueing slide riders, kids being pulled on small sleds, staff in reflective vests.\n- Every figure exhales visible breath fog on a natural rhythm; walkers leave subtle footprint trails on fresh snow; slide riders descend with real acceleration and a puff of snow at the runout.\n- Stage readable micro-stories: a family group photo with a tower glow behind them, a vendor handing over skewers with steam, a child hesitating at the top of a slide then going, maintenance staff replacing a lantern.\n- Crowds are autonomous agents with destinations, queues and pauses, not looping mannequins scattered at random.\n\n#### LIGHT CHOREOGRAPHY AND DYNAMISM\n- The city lighting is alive: slow coordinated color programs sweep across districts, towers shift hue over tens of seconds, lantern rows twinkle, and occasional gentle pulses travel down colonnades. Keep transitions elegant, never seizure-strobing.\n- Add fine atmospheric animation: snowfall density drifting with light wind, steam plumes, flags moving, faint aurora-like sky gradient, sparkle glints crawling across frost as the camera moves.\n- Reflections matter: colored light pooling on polished ice paths, blurred tower reflections in the frozen channel, glints in visitors' goggles and camera phones.\n\n#### EXPLORATION AND CONTROLS\n- Orbit, pan and zoom active immediately; one reset returns to the hero boulevard vista.\n- Camera presets: boulevard hero view; low plaza view between crowds toward the great tower; top of the ice slide looking down the lanes; bridge over the frozen channel with reflections; high aerial revealing the whole glowing city plan against the dark river.\n- Compact, elegant controls only: lighting program (classic multicolor \u002F single-hue elegance \u002F warm festival), snowfall intensity, crowd density, and a photo mode that hides UI.\n- Keep the camera comfortable: no trapping inside walls, sensible near-plane, gentle collision around structures.\n\n#### EXTREME DETAIL WITH DISCIPLINED PERFORMANCE\n- Allocate bespoke maximum detail to the central palace, nearest boulevard, hero slide and closest crowds; every preset frames at least one high-fidelity focal region.\n- Use nested LOD: full block-course geometry with internal glow near camera; silhouette-perfect simplified structures at distance; instanced crowds, lanterns, icicles, breath puffs and snow particles; merged far district geometry.\n- Provide a quality selector that reduces far crowd count, snowfall density and reflection cost before ever sacrificing ice translucency, block detail or the glow gradients.\n- Target smooth interaction on a modern laptop, clamp devicePixelRatio to 2, and keep memory rational. The outcome is the most overwhelming glowing ice city that still runs beautifully.\n```\n\n\u003C\u002Fdetails>\n\n\u003Ca id=\"prompt-09\">\u003C\u002Fa>\n\n\u003Cdetails>\n\u003Csummary>\u003Cstrong>09. Billion-Piece Forbidden City - First Snow Across the Imperial Palace\u003C\u002Fstrong>\u003C\u002Fsummary>\n\n```text\nCreate a monumental Three.js environment of Beijing's Forbidden City during the first clear snowfall of winter: an immense, ordered palace world of vermilion walls, golden tiled roofs capped with fresh white snow, marble terraces, gates, ceremonial courtyards, bridges, gardens, lantern warmth and distant palace layers unfolding toward the horizon. This should be instantly recognizable as the imperial palace complex in a breathtaking full environmental composition, not a generic Chinese temple courtyard, one isolated gate or a crowded festival vignette.\n\nThe scene must feel built from a billion precise details: roof tiles, ridge beasts, brackets, painted beam patterns, carved marble balustrades, stair reliefs, paving stones, red doors and studs, snow clumps, lantern tassels, bare branches, evergreen needles, courtyard footprints, frozen-water glints, tiny visitors and layer after layer of roofline receding in atmospheric winter light. Achieve the effect with procedural architectural systems, reusable components, instancing and LOD, maintaining clarity, respect and fluid exploration.\n\nIf you use Three.js, add an import map before the module script mapping \"three\" and \"three\u002Faddons\u002F\" to the same pinned version, and import only via those names. Generate architecture, snow, materials, foliage, figures, lanterns, lighting and animation procedurally without external image or model assets.
