Expand description
Noise function that outputs hybrid Multifractal noise.
The result of this multifractal noise is that valleys in the noise should have smooth bottoms at all altitudes.
Fields§
§octaves: usize
Total number of frequency octaves to generate the noise with.
The number of octaves control the amount of detail in the noise function. Adding more octaves increases the detail, with the drawback of increasing the calculation time.
frequency: f64
The number of cycles per unit length that the noise function outputs.
lacunarity: f64
A multiplier that determines how quickly the frequency increases for each successive octave in the noise function.
The frequency of each successive octave is equal to the product of the previous octave’s frequency and the lacunarity value.
A lacunarity of 2.0 results in the frequency doubling every octave. For almost all cases, 2.0 is a good value to use.
persistence: f64
A multiplier that determines how quickly the amplitudes diminish for each successive octave in the noise function.
The amplitude of each successive octave is equal to the product of the previous octave’s amplitude and the persistence value. Increasing the persistence produces “rougher” noise.
