Pelican Pier Cruiser

Beveled Micro-Voxel Coastal Pelican, Synced 44T/18T Cruiser & Streaming Pier

01 / What Was Built

Interactive, MagicaVoxel / Teardown-grade 3D micro-voxel diorama of a California brown pelican (Pelecanus occidentalis) happily riding a vintage seafoam-and-cream cantilever cruiser bicycle down a sunlit coastal timber pier, built in Three.js (0.186.1, WebGL2, HalfFloat AgX + BokehPass post-chain). Combines 5–6 mm beveled micro-voxel sculpting and 27-neighbor cavity AO with 60 Hz mechanically synced 44T/18T drivetrain kinematics, closed-loop 2-bone pelican leg IK, playful freewheel coasting and wheelies, and a continuously expanding wooden boardwalk over Gerstner voxel ocean swells.

02 / Creation Pipeline & Workflow

Engineered 100% procedurally in code with Gemini Carbon using a custom beveled micro-voxel sculpting engine (integer-grid SDF primitives, tubes & splines meshed with 3D edge bevels, spatial-hash tinting, and 27-neighbor voxel cavity AO — zero external 3D model or image texture files). Multi-scale voxel pitches (5–6 mm hero pelican & cruiser, 14–18 mm streaming timber pier bays, 45–80 mm ocean & harbor) are coupled to analytical 2-bone leg IK, a 54-link roller chain solver, and procedural WebAudio.

03 / Scene, Simulation & Optical Highlights

011:1 Metric Micro-Voxel Craft: 5–6 mm hero voxel pitch (14–18 mm pier props/planks, 45–80 mm ocean & harbor) on a 1.09 m-wheelbase vintage 26" (0.66 m) cantilever cruiser riding a 4.60 m-wide timber boardwalk whose 3.20 m bays continuously generate ahead while retaining every bay ridden behind.
02Live 60 Hz Kinematics & Avian Life: Exact v = ω · R wheel rotation (2.4444:1 44T sweetheart chainring to 18T rear cog), 54 advancing 3D roller-chain links, horizontal-leveling block pedals, closed-loop 2-bone leg IK keeping webbed orange feet planted through 360°, spring-damped gular throat-pouch jiggle, fluttering striped scarf, natural blink & joyful bill-clap, freewheel coasting, and a ~15 cm rear-axle front-wheelie lift.
03Coastal Optics & Post-Chain: Procedural PMREM sky & sun rig sweeping smoothly from crisp coastal afternoon to blazing sunset (4096×4096 shadows, auto-igniting warm amber pier lanterns & cruiser headlamp), AgX tone mapping, physical BokehPass DoF, UnrealBloomPass, and a custom RadialLensShader chromatic-aberration + anti-banding dither pass.
04Accessible HUD: Rendered cleanly outside post-processing with Cruise Speed (0.0×–2.0×), Day-to-Sunset lighting (0%–100% Coastal Day → Golden Hour → Sunset Glow), Coast Freewheel toggle (C), Ring Brass Bell (B, with procedural WebAudio chime), Front Wheelie (Space), and 5 camera presets (Hero Chase, Side Kinematics, Pelican & Basket, Wheel & Chain, Free Orbit via 1–5).

Metric Standard & Quality Gates

Coordinate & Metric Datum: 1 unit = 1 meter, +Y up, +X forward, +Z right (drive side), origin (0, 0, 0) on boardwalk top deck centerline midway between wheel axles (oceanMeanLevel = -2.350 m, pelicanCrestPeak = +1.385 m).
Automated Verification Suite: Automated checks verify all 16 blueprint metric tolerances, 27-part attachment graph integrity, 360° pedal-sole IK lock and fender/chainring clearance, PBR + matte-clay + no-post parity across 10 cameras (CAMERAS.md), and 60 Hz live walkthrough telemetry.
