A perlin noise generator. Can be created either via PerlinNoise(seed, octaves, persistence, scale) or minetest.get_perlin(seeddiff, octaves, persistence, scale).
Note that PerlinNoiseMap works faster.
Methods
get2d(pos)— 2d noise value atpos={x=,y=}get3d(pos)— 3d noise value atpos={x=,y=,z=}
== Examples ==TODO
