Open Simplex Noise

Build Status

This is an implementation of 2D, 3D, and 4D open simplex noise in crystal.

Installation

Add this to your application's shard.yml:

dependencies:
  open-simplex-noise:
    github: doughsay/crystal-open-simplex-noise
    version: "~> 1.0"
  ...

Usage

require "open-simplex-noise"

Instantiate a noise generator using an Int64 seed:

noise = OpenSimplexNoise.new(12345_i64)

Use the generate method, passing in either 2, 3, or 4 Float64s to generate noise:

noise.generate(1.0, 2.0)
#=> -0.08284024020120388

Examples

2D Noise:

2d-noise

3D Noise (2D slice):

3d-noise

4D Noise (2D slice):

3d-noise
