-The '''map generator''' is the [[Minetest]] component that generates the [[Maps|map]].

-== Overview ==
-This complex program, integrated into the game, can generate procedurally the [[Maps|map]], which is the world the player evolves in. It is based on Perlin noises, functions which allow associating to each point a random yet consistent value.
-== Generators ==
-=== Overview ===
-There are a number of different map generators. It is possible to choose between them when creating a [[Maps|map]]. Some [[mods]] may change them radically, also all map generators allow for a lot of configuration.
-* '''v5''': The oldest map generator, renewed for newer Minetest versions to feature biomes. It generates landscape based on 3D Perlin noise and is notable for its unique and somewhat strange terrain shape and occasional floating islands. Like v7, the biomes have to defined by mods first, otherwise the landscape will only be made out of stone (or some other default block).
-* '''v6''': The default map generator and successor of v5. Generated entirely using 2D noise and has somewhat more “realistic” terrfain. The weirdness of v5 is gone. This map generator has predefined biomes which can't be modified by mods but mods also don't have to define their own biomes before this map generator becomes useful.
-* '''v7''': An in-development map generator and successor of v6, with some innovations, uses 2D and 3D noise. It lets the modders define biomes in Lua. If no biomes are defined, then this generator only creates [[stone]]. This map generator is notable for many simple broad and deep “rivers” (or “ridges”) at Ocean level, but they can be disabled.
-* '''valleys''' (Minetest 0.4.14): Another map generator which generates a landscape featuring many hills, mountains and valleys. The valleys often contain rivers with [[River Water]]. The rivers are more sophisticated than in v7, since they are not at ocean level and change their height
-* '''flat''' (Minetest 0.4.14): This generates an (almost) entirely flat world with some biomes like in v7. Caves can still appear underground (if not disabled) and the map generator can be configured to add occasional hills and lakes.
-* '''fractals''' (Minetest 0.4.14): Generates a map based on a fractal. This is one of the more predictable map generators. It is possible to choose one of many fractals which are based on the Mandelbrot and Julia set.
-* '''singlenode''': By default, this produces a world with only [[air]] everywhere. To be precise, it produces only one type of [[Blocks|block]], air by default. This one is by far the simplest and fastest map generator, but in [[Subgames/Minetest Game|Minetest Game]], it is mostly useless. It is useful for mods which define their own map generation: first, air is generated, then the mod applies its own functions which generates the terrain.
-=== Gallery ===
-Here are examples of landscapes generated with the different map generators (using [[Games/Minetest Game|Minetest Game]]):
