Procedural-Forest

Procedural Forest

An infinite, walkable 3D forest generated on the fly in the browser. Every seed grows a different forest — terrain, trees, water, and lighting all stream in as you explore, with no load screens and no repeats.

Built as a single self-contained HTML file using Three.js.

Play

Just open procedural-forest.html in a browser. No build step, no install.

You can also serve it locally:

python3 -m http.server

then visit http://localhost:8000/procedural-forest.html.

Controls

• Click the scene to start walking
• W A S D — move
• Mouse — look around
• Shift — run
• On touch devices, an on-screen joystick appears automatically
• Grow a new forest button — regenerate the world with a new random seed

How it works

• A seeded mulberry32 PRNG plus 2D value noise with fractal Brownian motion (fbm) drives terrain height, tree placement, and biome variation, so the same seed always reproduces the same forest.
• The world is streamed in 140x140 unit chunks around the player, built and discarded as you move, giving the illusion of an endless forest.
• Trees, water, fog, and a day/night sky cycle are generated procedurally per chunk rather than loaded from assets.
