to get some image output, you can the use w.save_biome_map(0,0) to get an image for the tile (0, 0) saved to ./worldname_0_0.pgm
world creation consists of two layers:
-
creating a tile map which stores
- heightlevel
- temperature
- (calculated out of height + temp) the biome
- an offset (see next point)
... per pixel
-
create a "voronoi map" with the data of the pixel map
- scale up image by a factor (eg 10)
- add the offset for each pixel to make it look natural
- calculate neighbors for the created fields

created voronoi (regions):
created delaunay (neighbors):
