Adiyogi Divya Darshanam

112-ft Monument & 6-Act WebGPU TSL 3D Projection Mapping Showcase

01 / What Was Built

Interactive, metric-accurate 3D digital twin of the 112-foot (34.0 m tall × 45.0 m wide × 25.0 m deep) Adiyogi monument and consecrated Yogeshwar Linga forecourt in the Coimbatore Velliangiri foothills, built in Three.js (r187, native WebGPU + TSL node shaders + AgX post-processing). Transitions seamlessly from bright Western Ghats daylight through golden-hour sunset into a starry Coimbatore night, unlocking a choreographed 6-act (52.0 s) 3D architectural projection-mapping and surface galvo-laser show synchronized to a real-time WebAudio sacred score.

02 / Creation Pipeline & Workflow

Built with Gemini Carbon using a hybrid multi-tool pipeline: the hero Adiyogi bust was generated via Tripo AI H3.1 → Local Blender 5.2 Refinement & Cycles 4K Bake (serene facial topology preservation, KDTree-faired chest, integrated Vasuki cobra & catenary Rudraksha mala, grafted CrescentMoon & 360° Kundala hoops, plus 4K coated-steel PBR & RGBA feature mask), and the consecrated Sacred Nandi & 3-tier sandstone Nandi Peetham were built via Magnific + Tripo AI H3.1 Image-to-3D → Local Blender 5.2 Surgical Sculpt Repair & MikkTSpace Cycles 2K/1K PBR Bake (-12.5° axial Shringa Darshanam alignment, 2.5 mm OpenVDB -X flank reconstruction, and Chola brass ghungroo bells). Every surrounding temple structure — Yogeshwar Linga Shrine, twin 7-tier Alankara Deepam lamp towers, 32 dusk-igniting brass diyas, Trishuls, perimeter fence, and dual 13.5 m optical Projection Towers — was authored locally via build123d B-Rep CAD + Blender 5.2 Cycles 2K PBR, paired with Three.js WebGPU TSL projection/laser shaders and procedural WebAudio synthesis.

03 / Scene, Simulation & Optical Highlights

011:1 Metric Sanctuary Layout: 45.0 × 25.0 × 34.0 m matte-black welded-steel Adiyogi bust seated on a 56.0 × 38.0 × 2.0 m 9-step granite plinth (Y = 36.0 m crown peak) inside a 160 × 160 m dressed-stone courtyard with the YogeshwarLingaShrine, consecrated SacredNandi on a 3-tier sandstone Nandi Peetham (Z = 29.5 m, gazing inward along the -Z axis), twin 7-tier AlankaraDeepam bronze lamp towers, 32 flickering brass diyas, and PerimeterTrishulFence framed by the Velliangiri Mountain Range.
02Live 6-Act 3D Projection & Galvo-Laser Show (52.0 s): Two-stage Day → Sunset → Starry Night director gating 6 independent per-act TSL shader clocks (uT1..uT6) — I: Adi Guru (descending laser scan, Crescent Moon & Third Eye ignition), II: 112 Pathways (rotating chest Sri Yantra, Ida-Pingala-Sushumna channels & Saptarishi constellation), III: Ardhanarishwara & Vasuki (cosmic-indigo / vermilion-gold duality & bioluminescent emerald cobra), IV: Descent of Ganga (domain-warped FBM waterfall from Jata locks & plinth mist), V: Agni & Vibhuti (curl-warped magma fissures → 24k Chola gold wave → sacred matte Vibhuti ash), and VI: Mahadeva Darshanam (blazing 3D SDF Thirunamam & golden prana laser wavefronts).
03WebGPU TSL Optics & Sacred Synth: AgX tone-mapped WebGPU pipeline using unassociated 4K RGBA feature masks (isolating serene facial skin, Vasuki scales, Rudraksha mala beads, Kundala hoops, and steel seams), fwidth screen-space galvo-laser lines, CC0 2K daylight/sunset HDRIs with Rayleigh/Mie mountain haze, and synthesized Tanpura/Om drone, Damaru/Mridangam percussion, conch, and temple bells.
04Floating Glass HUD: Auto-collapsing top-right glassmorphic card with native Top-Layer HTML popovers (camera selector across 7 camera presets cam-01..cam-06 + dedicated Nandi 360° Close-Up cam-10 turntable preset, PNG capture, burst & camera bookmark; act selector for direct jump to Acts I–VI), Sun / Moon Day-to-Night toggle, Play / Pause + live scrubber, audio mute toggle, and damped free-orbit inspection.
