Procedural medieval island worlds from 4,100 hex tiles, built with WebGPU and a lot of backtracking.
- Modular Wave Function Collapse — 19 hexagonal grids solved independently with cross-grid constraint matching
- Layered Recovery System — unfixing, Local-WFC, and mountain fallbacks for 100% solve rate
- 30 Hex Tile Types — 6 rotations and 5 elevation levels each (900 states per cell)
- WebGPU Rendering — Three.js with TSL shaders for all custom visual effects
- BatchedMesh Optimization — 4,100+ cells in ~38 draw calls, 60fps on desktop and mobile
- Post-Processing Stack — GTAO ambient occlusion, depth of field, vignette, and film grain
- Dynamic Shadow Maps — frustum fitted to camera view for crisp shadows at any zoom
- Animated Water — caustic sparkles and coastal waves with cove-aware thinning
- Noise-Based Placement — Perlin noise for organic tree, building, and decoration clustering
- Seeded RNG — deterministic, reproducible maps from any seed
