About the noise types : the difference between the first two is just minor tweaks to the algorithm; they're not two entirely different noises. The output looks different, but once the noise is generated in the [1, -1] range, the output is brought back in the [0, 1] range by doing: kFractalNoise : noise * 0.5 + 0.5 kTurbulence : abs(noise) Very little differs between the two types, although you can tell the difference visually.
