Cython wrapper for the FastNoise Lite library

This wraps Auburns' great FastNoise Lite library using Cython for use in Python 3.6+

Installation

This package is available on the Python Package Index both as source and binary distribution for a variety of Python versions and platforms using the following command:

pip install pyfastnoiselite  # On some systems, "pip" has to be replaced by "pip3"

Note:

This wrapper currently lacks the domain warping functionality and documentation. Both are planned to be added in the future.

Usage

from pyfastnoiselite.pyfastnoiselite import FastNoiseLite, NoiseType

# Initializing with seed
noise = FastNoiseLite(seed=1337)
# Set noise type (optional, defaults to OpenSimplex2)
noise.noise_type = NoiseType.NoiseType_OpenSimplex2S

# Get 2D noise
print(noise.get_noise(34, 22)) # 0.7130074501037598
print(noise.get_noise(100, 110)) # -0.614801287651062

# Get 3D noise
print(noise.get_noise(95, 100, 30)) # -0.45421651005744934


import numpy as np

Xs = [3, 57, 95]
Ys = [4, 13, 100]
Zs = [0, -4, 30]
coords = np.array([Xs, Ys, Zs], dtype=np.float32)
# Generate noise for each coordinate
print(noise.gen_from_coords(coords)) # [0.11303097 -0.5841235  -0.45224023]
