A complete Japanese pagoda, generated from parameters — not a scaled pre-made model.

Move a slider and the architecture rebuilds itself: floors, footprint, taper, column grid, roof curvature, wall type, balconies, stairs, lanterns. Every piece of geometry is computed at runtime in the browser with Three.js.

Roof tiles are geometry, not a texture. Each roof is lofted eave-to-ridge with a concave profile and lifted corners, then corrugated into hongawara tile courses phase-locked to world space — courses stay parallel while the roof narrows. Every course ends in a round cap tile; hip ridges follow the curved corner chains and kick up at the tips. ~60–100k triangles per roof.

Full PBR materials (CC0 scans) with world-scaled UVs, so texel density stays uniform across the merged building.

Real structural detail: two-tier exposed rafters, bracket complexes on pillar tops, kōran-railed balconies above each roof skirt, central shinbashira, gilded sōrin spire, emissive chōchin lanterns on every eave.

Fast: everything merges to one mesh per material — roughly 14 draw calls, even at the 7-storey / ~600k-triangle setting.

A karesansui court re-fits to the tower's footprint and entrance side on every rebuild. The raked gravel is analytic, not a texture: every furrow is a level set of a single scalar potential that meanders in long parallel lines across the open "sea" and turns into concentric rings around each island — podium, stone group, lantern foot — then unwinds back into the sea lines, exactly the way a real rake track does. Boulders are grown from noise-displaced icosahedra and planted in odd-numbered sanzon-seki groups; kasuga stone lanterns face the tower and always leave the stairs a clear approach.

Rain with wind direction and streak controls, plus an in-place wet-surface shader: puddles by flatness, darkening, gloss, droplets, live ripples.

Snowfall with a real accumulation shell — coverage, thickness, relief, sparkle.

A procedural sakura grove: tube-bark trees, instanced blossom cards, tumbling petal drift, and petals that settle and accumulate on surfaces.

Four physically-based lighting rigs — Golden Hour, Misty Dawn, Starry Night, Daylight Sky — each a full setup: HDRI/procedural-sky IBL, key/fill/rim/kick, softboxes, façade uplighters, roof crown light, fog, ACES tone mapping and bloom.

Live lil-gui panel over Dimensions, Structure, Roof + Tiles, Walls + Openings, Balcony + Base, Lanterns, Variation (perfect / semi / organic symmetry, seed, 0–100 detail), Zen Garden, Weather and Sakura Grove. Building presets ship for Five-Story, Three-Story Compact, Seven-Story Grand and Squat Pavilion. A high/low render-quality switch keeps it usable on weaker GPUs.

One click writes the current tower to .glb for Blender, Unreal or Unity.

Three.js + Vite, plain ES modules, no framework, no build magic. npm install && npm run dev. Ships with a headless smoke test that generates every preset plus stress configurations. Modular by design — the temple, garden, weather and grove systems each own their own materials and never touch each other's.
