Amazonian Nature Aquascape & Altum Angelfish Sanctuary

1:1 ADA 90-P Rimless Nature Aquarium, 60 Hz Altum Angelfish & Articulated Sump Rig

01 / What Was Built

Interactive, gallery-grade 3D ADA 90-P (90 × 45 × 45 cm) rimless nature aquarium built in Three.js (r186, WebGL2, 4x MSAA HalfFloat + AgX post-chain). Combines a Takashi Amano–inspired bogwood-and-Seiryu-stone underwater landscape with 60 Hz biomechanically swimming Pterophyllum altum angelfish, 18 schooling Cardinal Tetras, grazing Caridina shrimp and zebra snails, real-time GLSL water caustics/meniscus/pearling, and an articulated gallery cabinet housing a stainless canister filter and live CO2 bubble-counter rig.

02 / Creation Pipeline & Workflow

Engineered with Gemini Carbon across four specialized local asset pipelines: (1) Blender 5.2 profile lofts + Cycles 2K PBR bakes for rigged Altum angelfish (silhouette IoU = 0.808), Cardinal Tetras, shrimp, and snails; (2) #F2F2F2 studio sprites reconstructed locally on-device via the Local TripoSG pipeline + Blender watertight repair & 4K bark micro-normals for driftwood arches and Seiryu stones; (3) exact metric build123d CAD + Cycles 2K PBR for the ±80° hinged gallery cabinet, stainless canister filter, dual-gauge CO2 regulator, and CNC LED luminaire; and (4) runtime Three.js analytic heightfields, BVH flora ray-snapping, and custom GLSL underwater caustics/meniscus shaders.

03 / Scene, Simulation & Optical Highlights

  1. 011:1 Metric Gallery Setup: 0.90 × 0.45 × 0.45 m 10 mm low-iron OptiWhite tank on a 0.78 m dark gallery stand with 0°–80° hinged front doors, external filter hoses, right-side borosilicate CO2 U-bend + 96-bubble ceramic diffuser, lily pipes, and a suspended CNC LED luminaire.
  2. 02Live 60 Hz Ecosystem: 2 hero Pterophyllum altum gliding with C-to-S spine bending, turn-rate banking, and pectoral fin rowing; 18 Boids-schooling Paracheirodon axelrodi; 5 walking Caridina shrimp and 3 Neritina zebra snails surface-projected onto stones and wood; 5 flora species swaying in a shared lily-pipe flow field.
  3. 03Underwater Optics & Post-Chain: Capillary 3.5 mm wave meniscus, projected underwater-only caustics, volumetric light shafts, Beer-Lambert depth absorption, rising O2 leaf-pearling streams, and peripheral thin-lens DoF.
  4. 04Gallery HUD: Rendered cleanly outside post-processing with 3 lighting moods (Daylight, Twilight, Moonlight via 1–3), 5 camera views (Gallery Front, Sand River, Submerged Arch, Pedestal, Free Orbit via Shift+1–5), Cabinet Doors (O), and clean-screen toggle (H).
