Struct perlin2d::PerlinNoise2D

pub struct PerlinNoise2D { /* fields omitted */ }

Perlin Noise struct

Member variables:

• octaves - The amount of detail in Perlin noise.
• amplitude - The maximum absolute value that the Perlin noise can output.
• frequeny - The number of cycles per unit length that the Perlin noise outputs.
• persistence - A multiplier that determines how quickly the amplitudes diminish for each successive octave in a Perlin-noise function.
• lacunarity - A multiplier that determines how quickly the frequency increases for each successive octave in a Perlin-noise function.
• scale - A Tuple. A number that determines at what distance to view the noisemap.
• seed - A value that changes the output of a coherent-noise function.
• bias - Amount of change in Perlin noise. Used , for example, to make all Perlin noise values positive.
