Class PerlinNoise

java.lang.Object
net.minecraft.world.level.levelgen.synth.PerlinNoise
public class PerlinNoise extends Object
This class generates multiple octaves of perlin noise. Each individual octave is an instance of ImprovedNoise. Mojang uses the term 'Perlin' to describe octaves or fBm (Fractal Brownian Motion) noise.
