Array of characters to use for rendering, ordered from lowest to highest intensity
the base frequency of the Perlin noise. Higher values result in more rapid changes.
the number of noise layers to combine for fractal noise. More octaves add detail.
controls the amplitude of each octave. Lower values reduce the influence of higher octaves.
controls the frequency of each octave. Higher values increase the frequency
