An implementation of Ken Perlin's improved Perlin noise algorithm in Elixir.

This library provides functions to generate 3D Perlin noise, which can be used for procedural generation of textures, terrains, and other natural-looking patterns. It includes both single-octave noise generation and multi-octave noise for more complex and detailed results.

The implementation is based on Ken Perlin's improved noise function from 2002, which addressed some of the visual artifacts present in his original 1985 algorithm.

• 🌐 3D noise generation
• 🔁 Optional repetition of noise pattern
• 🏔️ Multi-octave noise for more natural-looking results
• 🎛️ Configurable persistence for octave-based noise

The package can be installed by adding perlin to your list of dependencies in mix.exs:

def deps do
  [
    {:perlin, "~> 0.1.0"}
  ]
end

iex> Perlin.noise(3.14, 42.0, 7.0)
0.5684599793920001

iex> Perlin.octave(3.14, 42.0, 7.0, 4, 0.5)
0.5530014285141335
