World Orogen — Procedural Planet Generator
World Orogen is a free, browser-based procedural planet generator. Build realistic terrestrial planets shaped by tectonic plates, erosion, and volcanism — no download or account required.
How It Works
Start by adjusting sliders for detail level, number of tectonic plates, continents, and terrain roughness. Click "Build New World" to generate a unique planet with realistic continental shapes, mountain ranges, ocean trenches, volcanic island chains, and hotspot volcanism. Every planet is procedurally generated and completely unique.
Key Features
- Tectonic plate simulation with convergent, divergent, and transform boundaries
- Multiple erosion types: glacial (fjords, U-shaped valleys), hydraulic (river valleys), and thermal (talus slopes)
- Climate simulation with seasonal wind patterns, ocean currents, precipitation, and Köppen climate classification
- Hotspot volcanism with drift-trail island chains (like Hawaii)
- Interactive plate editing — select multiple plates for batch land/ocean toggling with visual preview before rebuild
- Heightmap import — bring your own equirectangular B&W heightmap (Earth, Mars, hand-drawn) and run full climate simulation on it
- Multiple visualization modes: terrain, satellite biome, climate, and heightmap
- 26 detailed inspection layers for geology, atmosphere, ocean, and climate
- High-resolution equirectangular map export up to 65,536px wide
- Shareable planet codes — copy a code to share your exact planet with others
Use Cases
World Orogen is used by worldbuilders, game developers, tabletop RPG players, fantasy authors, and anyone who needs realistic terrain. Export heightmaps for use in game engines like Unity or Unreal, or download satellite-style maps for your D&D campaign setting. The climate simulation produces realistic biome distributions for believable fantasy worlds.
Share Your World
Every planet has a unique planet code. Share the URL (e.g. orogen.studio/#CODE) to let anyone recreate your exact world — including any tectonic plates you've edited by hand.
