Dungeon Forge

A deterministic procedural dungeon generator you can watch build itself, room by room. Rooms are scattered and shoved apart, triangulated, wired into a corridor graph, carved into a tile grid, and dressed with theme-specific props, liquids, lights, and particles — **every stage seeded from a single number, so any seed rebuilds the exact same dungeon.** Rendered live with Three.js. - One seed, one dungeon. A single mulberry32 stream is threaded through every stage — scatter, separation, triangulation, room roles, carving, decoration. The same seed always yields the same map, down to the last torch. Change one digit and get an entirely new floor. - A real generation pipeline, visualized. Watch it run: **scatter → separate → Delaunay → MST + loops → semantics → carve → rasterize + BFS → decorate.** Each step lights up in the HUD as it happens, and you can scrub the whole build animation or skip it. - Graph-based layouts. Rooms are Delaunay-triangulated, reduced to a minimum spanning tree for guaranteed connectivity, then selectively re-looped so the dungeon has shortcuts and cycles instead of a boring spanning-tree spider. - Room semantics. A BFS from the entrance assigns depth and difficulty, then tags rooms as entrance, combat, elite, treasure, shrine, or boss based on where they sit on the critical path — so the layout reads like a real level, not just connected boxes. - Five hand-tuned themes (plus AUTO, which picks one from the seed): **Ancient, Molten, Frost, Grim, Verdant.** Each swaps the palette, lighting rig, liquids (lava / water / miasma), props, particle system (embers / snow / spores / wisps), and torch color. - Procedural everything. Stone, cracks, runes, portals, and light shafts are all generated to canvas textures at load; geometry is built from primitives; nothing is loaded from disk. - Instanced rendering. Thousands of floor tiles, walls, props, and decorations are drawn with InstancedMesh, so an 80-room dungeon with ~6,000 floor tiles still holds a high frame rate. - Custom post-processing. A hand-written pipeline — bright-pass bloom, separable blur, tilt-shift focus band, cool-shadow / warm-highlight color grade, vignette, and film grain — gives the whole thing its painted-miniature look. Toggle it live for an A/B. - Live readouts. Room count, links · loops, critical-path length, floor-tile count, light count, generation time, draw calls, triangles, and FPS — all updating as you forge. - Overlays. Flip on the graph overlay to see the Delaunay edges, MST, and loops in world space, or the difficulty heatmap to see how the danger ramps from entrance to boss. - Object layers. Toggle whole categories of the scene on and off live — **props, torches, particles, liquids, lights** — without re-forging. Strip it back to bare architecture, or kill the lights and watch it read by torchlight alone. - Responsive & touch-ready. The control panel collapses to a slim bar (on desktop and mobile) so the dungeon has the whole screen, and every target is sized for a fingertip on phones/tablets. The panel (top-left) drives everything: type a seed (or roll the dice), pick a theme, and adjust rooms, loopiness, and decor density. Every change re-forges deterministically. Dungeon Forge is the open-source project majidmanzarpour/threejs-procedural-dungeon (https://github.com/majidmanzarpour/threejs-procedural-dungeon) by majidmanzarpour, released under MIT. Ion packages it unmodified from commit 0a2aa0980028, adding only a manifest, an icon and a storage compatibility script.
