Cartography for the fictional worlds




The project’s goal is the procedural generation of really huge spherical planets with following features:

  • full-fledged river systems, highland lakes, and custom outlines of the continents;
  • biomes with a placement dependent on longitude;
  • the gradual transition of biomes is achieved by the mutual penetration of their parts (yin-yang boundary);
  • various vector data defining the relief features (continents and lakes boundaries, riverbeds, biomes boundaries, height contours, tiles and sectors, etc);
  • full size planets with correct spherical geometry of the relief features;
  • the procedural generated planets are data instantly suited for existing Geographic Information System (GIS) software;

Examples of planets

Serpento. Enjoy the planetary biomes.


On planet Mandelbrot the ancient alien civilization left a message in the form of the continents.
