Use the chapter controls to explore the bridge, machinery, flooding sequence and teardown. The standalone HTML is linked below. ## Original build prompt ``` Build a single self-contained HTML file: an interactive, fully procedural 3D robotic ocean liner called "Titanic NX-12" (brand mark "Teuthis", third piece of a white-and-violet series), rendered with three.js r170 loaded via an importmap from jsDelivr. No external models, textures or images; every part is generated in code at load time. Target quality: a premium product-simulator / engineering teardown page with ~2,200 real moving parts. LOOK Bright studio look: near-white canvas-drawn background with soft lavender corner gradients and a faint dot grid; white glossy clearcoat superstructure, near-black hull and machinery, violet accents (#8a4dff), glowing violet emissives on engines and navigation lights, subtle iridescent nacre-like finish on interior decks and bulkheads (MeshPhysicalMaterial iridescence). No tone mapping; calibrate hemisphere, key (soft PCF shadows), fill, rim and RoomEnvironment PMREM so white surfaces keep their shading and never clip. Invisible shadow-catcher floor plus a faint contact blob. Optional faint ocean-plane reflection only on the hull waterline. Post: EffectComposer, HalfFloat MSAA target, GTAO (background, floor, emissives and decorative lines hidden in the AO prepass), UnrealBloom with threshold ~1.5 so only emissives glow, OutputPass. Procedural surface-detail shader injected via onBeforeCompile: rivet rows following plate edges, seam grooves, porthole rings, deck-plank grooves, clustered bolt patterns, driven by per-vertex metric surface coordinates and distance-to-edge attributes; antialias with fwidth; per-instance seeds. GEOMETRY TOOLKIT paramPanel(fn(u, v), ranges, thickness): thick parametric panel (outer, inner, rims with correct winding), normals oriented away from a reference point, metric UV and edge-distance attributes for the detail shader. Also revPanel (surface of revolution for funnels and masts), extruded gears and pistons, spline tubes for pipes and cables, rounded boxes and cylinders; merge each part per material. HULL & SUPERSTRUCTURE (body frame: origin at waterline midships, +z forward, +y up, +x starboard) Classic Titanic proportions: length ~269 m scaled, fine entry, full midships, counter stern. 42 main hull plates in longitudinal and transverse seams, black boot-topping, white upper hull, violet accent stripe along the sheer. Four funnels (the fourth dummy): three operational with internal exhaust trunks and violet rim lights, one false with solid interior. Funnels generated as surfaces of revolution with guy-wire attachment points. Multiple decks: boat deck with 20 lifeboats on davits (each boat has oars, benches, and can be swung out), promenade decks, A–G decks with portholes and windows, bridge with wing platforms, masts with crow’s nests and rigging. Interior cutaways (visible during teardown): grand staircase with ornate balustrades, first-class cabins, boiler rooms, engine rooms, coal bunkers, watertight bulkheads with doors. MACHINERY & SYSTEMS Triple-expansion engines and low-pressure turbine: reciprocating engines with visible pistons, crossheads, connecting rods, crankshafts, and a separate turbine with rotor and stator blades. All driven by a single shared crank phase. 29 boilers (simplified to 12 visible units) with furnace doors, pressure gauges, and glowing fireboxes. Steam pipes, condensers, and bilge pumps. Propulsion: three propellers (two wing, one centre) with individual shafts; rudder with hydraulic actuators. Anchor chains and windlasses. Navigation: binnacle, telegraphs, searchlights, and wireless room with spark-gap transmitter glow. 44 “service arms” / robotic tentacles (analogous to cirri): two rings of telescoping maintenance arms that can extend, curl, and wave; GPU-instanced links with violet grip rings and tips. Quaternion FK per frame with travelling wave and droop. TIMELINE (pure stateAt(t), ~32 s loop, deterministic) Departure (funnels smoking, flags, gentle bob) → Full speed (engines spin up, propellers turn, wake suggestion) → Bridge & Optics (searchlights sweep, telegraphs ring) → Boat Deck (davits swing out, one lifeboat lowers) → Engine Room (cutaway, pistons and turbine accelerate, boiler fires pulse) → Damage (starboard hull plates lift off in a wave, exposing compartments) → Flooding (water-level rise simulated by scaled fluid capsules, bulkhead doors close, list increases) → Sinking sequence (bow dips, stern rises, final plunge with cascading part separation) → Teardown (every major assembly flies outward with cascaded delays and free spin, 360° turntable) → Reassembly → Departure again. Spin phases from integral of trapezoid speed profile. Per-chapter camera shots in body axes with eased blends; during Flooding the camera dollies along the length. UI (HTML/CSS/SVG, Inter Tight + IBM Plex Mono) Logo, “Live sim” pill, model line + title “RMS Titanic, Bridge to Boilers” + date, chapter pills, left nav with sub-lines, right cards: Buoyancy / List angle with 6 s sparkline, Engine RPM bar, Boiler pressure bars (live), Battery / Power; bottom status “Chapter · NN% apart” with progress track and timecode. 3D-anchored callouts (dot on the real part, leader line, label card) in two collision-spaced columns. Pills/nav seek with smooth camera blend; drag to orbit; double-click or R for auto camera; space to pause; responsive phone layout; reduced-motion support; adaptive quality governor. CAPTURE AND AUDIO Expose window.capture(t) (capture mode: no rAF, no CSS transitions). Render 1920×1080 at 60 fps headless with Playwright, retime to exactly 15 s with linear frame blending, encode H.264 CRF 17 with AAC. Original synthesized score (numpy/scipy, no samples), one bar per chapter so changes land on downbeats, with synced sound design: engine thrum, boiler roar, telegraph bells, davit creaks, hull-plate lifts, flooding gurgles, bulkhead slams, final structural groans, teardown clinks, reverse swell, departure whistle; normalize to about −21 LUFS. ``` --- This mirrors the structure, technical constraints, part density, material system, animation style, and UI of the original Nautilus prompt while adapting every element to a mechanical Titanic. Paste it into Claude (or another strong coding model) and request a single self-contained HTML file.
