GDFastNoiseSIMD

gdfastnoisesimd is a Godot 3.0 module for the FastNoiseSIMD lib. Thanks to @Auburns.

FastNoiseSIMD is a library for noise generation that uses SIMD(Single Instruction, Multiple Data) instructions.

warning

If you are having problems compiling or getting errors while using the library in Godot, try commenting the line #define FN_COMPILE_AVX2 in the file FastNoiseSIMD.h which is inside the FastNoiseSIMD directory in the gdfastnoisesimd module (Probably already be commented out by default).

EXAMPLE

extends Node

var noise = GDFastNoiseSIMD.new()

func _ready():
  # Choose a seed to generate the noise. The results will be different for different seeds.
  noise.setSeed(16549)
  # Choose the type of noise.
  noise.setNoiseType(noise.SIMPLEX)
  # Always returns a one-dimensional float array.
  # If the size of the Z dimension is a multiple of 8 there is a slight performance boost.
  var arrayFloat = noise.getNoiseSet(0, 0, 0, 16, 16, 16)
  # All outputs are approximately bounded from -1.0 to 1.0, except for distance functions on cellular noise.
  print(arrayFloat)
  
  # 2D noise
  var otherArrayFloat = noise.getNoiseSet(0, 0, 0, 1, 16, 16)
  print(otherArrayFloat)
  
  # You can also call the specific noise function. 
  # Check out the DOC/API for all available functions.
  var arrayFloatPerlin = noise.getPerlinFractalSet(0, 0, 0, 16, 16, 16)
  print(arrayFloatPerlin)
