Class PerlinSimplexNoise

java.lang.Object

net.minecraft.world.level.levelgen.synth.PerlinSimplexNoise

public class PerlinSimplexNoise
extends Object

This class generates multiple octaves of simplex noise. Each individual octave is an instance of SimplexNoise. Mojang uses the term 'Perlin' to describe octaves or fBm (Fractal Brownian Motion) noise and this class does not actually generate Perlin noise.
