Source 
pub fn fbm(
    x: f32,
    y: f32,
    octaves: u8,
    persistence: f32,
    lacunarity: f32,
) -> f32
Expand description

Classic 2-D fBm over Perlin noise.

§Arguments

  • persistence – amplitude multiplier per octave (0.5 = halved each time)
  • lacunarity – frequency multiplier per octave (2.0 = doubled each time)
