Fast noise is a direct port from the implementations by Jordan Peck. The Dart version currently does not yet leverage SIMD for better performance.

fast_noise offers both 2D and 3D noise generation with noise2 and noise3

The following noise types are available:

Try out some settings here

Cellular Noise #

import 'package:fast_noise/fast_noise.dart'; main() { var arr2d = noise2(w, h, noiseType: NoiseType.Cellular, octaves: 5, frequency: 0.015, cellularReturnType: CellularReturnType.Distance2Add); }

import 'package:fast_noise/fast_noise.dart'; main() { var arr2d = noise2(w, h, noiseType: NoiseType.Perlin, octaves: 3, frequency: 0.05);

import 'package:fast_noise/fast_noise.dart'; main() { var arr2d = noise2(w, h, noiseType: NoiseType.SimplexFractal, octaves: 4, frequency: 0.0075)

You can also call a noise type directly:

var noise = new ValueNoise(interp: Interp.Quintic, octaves: 5); // generate 512x512 for (int x = 0; x < 512; x++) { for (int y = 0; y < 512; y++) { noise.singleValueFractalBillow2(x.toDouble(), y.toDouble()); } }
