noisy

Generate fractal noise from from the command line. Great for rendering smoke, fluids, and terrain. Simply install noisy with NPM and run a command to produce a png image. In the case of 3 dimensions, noisy will generate a series pngs over a range of z values.

Features

• Supports Perlin and Worley noise
• Can generate 2D and 3D noise
• Seamless tiling in all dimensions
• Easy to use

Noise Types

worley_pillows

worley_ridged_pillows

Installation

npm install -g noisy

Recipes

Generate 2D perlin noise

noisy -t perlin_fbm -l medium -d 2

Generate 2D worley noise

noisy -t worley_pillows -l medium -d 2

Generate 3D worley noise

noisy -t worley_gems -l medium -d 3 -s 32
