PerlinNoise | Simple perlin noise implementation | Generator Utils library

I am trying to generate a grid across my map and add nodes depending on the perlin noise value. Depending on the value obtained from the perlin noise at a location, I will add a new Node which will be of a certain type e.g. Mountain, Water etc to represent terrian. Here I am trying to make it so that if the value is > 0.5, this mean it's only mountains and so a black coloured cubes should surround the mountain areas, However, my black cubes do not match the mountain areas from the perlin noise and I cannot seem to figure out why I am going wrong. Would appreciate any insight into how I could go about achieving this.

[EDIT] Solved, see below for solution.

I am trying to generate a height map using Perlin Noise, but am having trouble with generating truly unique maps. That is, each one is a minor variation of all the others. Two examples are below:

And here is my code (most was just copied and pasted from Ken Perlin's implementation, though adapted for 2D):

i understood using perlin-noise to make a pattern with cubes but what i want to is a random terrain plain land such as this game called muck (that has been devolped by unity)

i've tried doing:

So I am creating an endless terrain.

I can create the terrain but my chunks have gaps betwean them and they don't align properly.

I think the problem might be caused by my Noise Generation script, but I am not sure.

This is my Noise Generation script

I need a little help, I have this Perlin noise function, but I don't know how to properly create offsets.

I am using this to create infinite terrain generation and when I use this script it the noise values of individual chunks don't fit together properly. And they create holes.

Is there a way of fixing this ?

I need a small help, I am trying to create an Island generator using Unity.

However I do not know how to make circular fall Off map.But instead I manage to create an island that is more of a box shaped island.

This is what I am doing:

1. I am generating Height map using Perlin noise
2. I will generate FallOff map and substract it from Perlin noise
3. The Island getsgenerated, but instead of having circular shape the island hasbox-like shape

I want to create this

This is my Perlin noise function

I'm trying to create a FBM texture using the module perlin-noise, but it takes a very long time to execute. I've implemented multiprocessing, only to find that the program was still running off a single core. I've tried looking for other people with the same problem, but most threads were 7+ years old and / or involved problems and solutions related to different OSs.

My OS is Windows 8.1, I have a quad-core CPU, and I'm running Python 3.9.2

Here is the program:

UPDATE

I found out that the mesh center of the mesh object is not at 0,0,0. Does that do anything?

I have the following problem. I am generating a terrain from Perlin noise and that works fine. However, as soon as I try to instantiate any objects on it, some are spawned in the terrain area and some completely outside. When I reset the object's transform, it teleports to (0,0,0) as expected, but when I reset another object, that was not instantiated at runtime, the (0,0,0) is at a completely different location! I have no parent set to these objects and no parent set to the other object as well. Below is my code for generating the objects:

I'm trying to find the best way to generate perlin-noise-based cube voxel asteroids, but cannot seem to find a consistent method to do so.

I've tried to use this perlin noise library: https://github.com/warmwaffles/Noise/blob/master/src/prime/PerlinNoise.java

Along with this static method to get 3D noise out of it:
