// HOW TO IMPLEMENT A PERLIN NOISE FONCTION TO GET A TERRAIN HEIGHT IN UNITY
using UnityEngine;

  /// octaves : Number of iterations (the more there is, the more detailed the terrain will be)
  /// persistance : The higher it is, the rougher the terrain will be (this value should be between 0 and 1 excluded)
  /// lacunarity : The higher it is, the more "feature" the terrain will have (should be strictly positive)

3d perlin noise unity

public static float Perlin3D(float x, float y, float z, float density, float scale){
  float XY = Mathf.PerlinNoise(x, y);
  float YZ = Mathf.PerlinNoise(y, z);
  float ZX = Mathf.PerlinNoise(z, x);
  
  float YX = Mathf.PerlinNoise(y, z);
  float ZY = Mathf.PerlinNoise(z, y);
  float XZ = Mathf.PerlinNoise(x, z);
  
  float val = (XY + YZ + ZX + YX + ZY + XZ)/6f;
  return val * scale;
}

Unity get perlin noise 3d

    public static float PerlinNoise3D(float x, float y, float z)
    {
        float xy = Mathf.PerlinNoise(x, y);
        float xz = Mathf.PerlinNoise(x, z);
        float yz = Mathf.PerlinNoise(y, z);
        float yx = Mathf.PerlinNoise(y, x);
        float zx = Mathf.PerlinNoise(z, x);
        float zy = Mathf.PerlinNoise(z, y);

        return (xy + xz + yz + yx + zx + zy) / 6;
    }
