Random World Generation with Fractal Terrain

Short video demonstrating the stages of creating a random world. After creating a random fractal heightmap, temperature bands are generated, wind and rain is simulated (including realistic "rain shadows" caused by mountains) and rivers flow.

Temperature Simulation


  • New, unique, random terrain every time!
  • Realistic wind and rain simulation
  • Detailed temperature bands
  • Detects contiguity of terrain bodies
  • Tweaked for optimum terrain variance, for balanced game play.
  • Supports maps of up to 2048 by 2048
  • Exports data to PNG
  • Exports data to simple binary format
  • Actually fairly fast now

For windows, but works on Linux with wine.
