Perlin-Noise-Godot

This project aims to create a simple script for generating heightmaps in godot.

This godot script generates a heightmap image that can be used for 2D or 3d terrains in godot. This is performed using a translated version of the perlin noise algorithm.

The original implementation was written in Java : Noise2D

The script, whilst fully functional could use some performance tweaks to improve the loading time within the godot game enigne. However using a seperate thread and reducing the width/height of your output image will reduce the performance requirements.

How to use:

Put this script somewhere in your godot project and instance the script, Once the script has been instanced create a variable to store the result of the script (the image texture):

var heighmapGeneratorScript=load("res://Scripts/heightmap-generator.gd").new()
var imagetexture = heighmapGeneratorScript

Once the heightmap image generated by the script is returned it can then be used to generate your mesh. read the instructions below on a simple way to add the heightmap to a meshInstance.

Applying the heightmap:

As this script only generates the heightmap i.e doesent apply the image to a terrain another script is required to apply the image to the terrain. I recommend TheHX's heightmap.gd script

Contributions

A special thanks to the godot forum community for their performance suggestions.

Contributions to the script are always welcome, just submit a pull-request after reading the guideline: Guideline

Implementations - Must Read

Whilst the godot implementation is functional and complete, the CSharp version is currently a work in progress as such it currently only outputs a 2D array.
