Generation of a random geo-strategic map with a given amount of areas and average connectivity approaching six for large amount of areas (randomised hex placement).
Steps:
- Generate uniform random points on the sphere.
- Run Lloyd's algorithm on it about 30-50 times with the right metric (see: great circle distance, area of triangles and polygons on a sphere, getting the centroid of a polygon on a sphere).
- Generate the Voronoi triangulation for the point set; these are the areas.
For some non-uniformity, possible algorithm:
- Randomise parts of the boundaries as per the polygon map generation article.
ToDo:
- Random heighmap generation on the sphere (procedural planet?)
- Moisture
- Temperature
- Evapotranspiration
- Decide on biomes based on that
- Rivers (& lakes) based on precipitation
