fast_noise #

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

Usage #

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

The following noise types are available:

• CellularNoise
• CubicNoise
• PerlinNoise
• SimplexNoise
• ValueNoise
• WhiteNoise

Demo #

Examples #

Cellular Noise #

import 'package:fast_noise/fast_noise.dart';

main() {
  var arr2d = noise2(
      width,
      height,
      noiseType: NoiseType.cellular,
      octaves: 5,
      frequency: 0.015,
      cellularReturnType: CellularReturnType.distance2Add,
  );
}

import 'package:fast_noise/fast_noise.dart';

main() {
  var arr2d = noise2(
      width,
      height,
      noiseType: NoiseType.perlin,
      octaves: 3,
      frequency: 0.05,
  );
}

import 'package:fast_noise/fast_noise.dart';

main() {
  var arr2d = noise2(
      width,
      height,
      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());
    }
  }
