Utility functions for working with noise maps.
Visualization
{:ok, noise} = Isotope.Noise.new(%Isotope.Options{seed: 42})
nm = Isotope.Noise.noise_map(noise, {80, 40})
Isotope.Utils.show_noisemap(nm)This renders the noise map to the terminal using ANSI 256-color codes.
Each value is mapped to a color index and displayed as a ▒ character.
Requires a terminal with ANSI color support.
Summary
Functions
Shows the given noise map on the stdout using ANSI color codes.
Functions
@spec show_noisemap(Isotope.NoiseMap.t()) :: :ok
Shows the given noise map on the stdout using ANSI color codes.
This won't work if your terminal doesn't support ANSI color codes.
