Struct Fbm

pub struct Fbm<Noise> {
    pub noise: Noise,
    pub octaves: u32,
    pub gain: f32,
    pub lacunarity: f32,
    pub fractal_bounding: f32,
}

Fractal Brownian motion (fBm) noise.

fBm noise is created by calling the base noise octaves amount of times with increasing frequency and decreasing amplitude.

Note: This modifier assumes the base noise to return values in the [-1, 1] range.

Fields

noise: Noise

octaves: u32

gain: f32

lacunarity: f32

fractal_bounding: f32

Performs copy-assignment from source.

impl<Noise: PartialEq> PartialEq for Fbm<Noise>

fn eq(&self, other: &Fbm<Noise>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
