Struct OpenSimplex2

pub struct OpenSimplex2;

2/3/4 dimensional OpenSimplex2 noise. Fast variant.

You can improve the visual isotropy for certain orientations using the improve_* methods provided by the OpenSimplexNoise trait.

Trait Implementations

impl Clone for OpenSimplex2

fn clone(&self) -> OpenSimplex2

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OpenSimplex2

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for OpenSimplex2

fn default() -> OpenSimplex2

Returns the “default value” for a type.

impl Noise for OpenSimplex2

fn seed(self, seed: i32) -> Seeded<Self>

where Self: Sized,

Sets a seed to be sampled with.

fn frequency(self, frequency: f32) -> Frequency<Self>

where Self: Sized,

Modifies a noise with a frequency multiplier.

fn fbm(self, octaves: u32, gain: f32, lacunarity: f32) -> Fbm<Self>

where Self: Sized,

Creates a fractal from this noise with the provided octaves, gain and lacunarity.

fn ridged(self) -> Ridged<Self>

where Self: Sized,

Modifies a noise to create a peak at 0.

fn triangle_wave(self, frequency: f32) -> TriangleWave<Self>

where Self: Sized,

Applies a triangle wave to the output of a base noise function.

fn tileable(self, width: f32, height: f32) -> Tileable<Self>

where Self: Sized,

Creates a tileable 2D noise from a 4D noise.

fn mul_seed(self, value: i32) -> MulSeed<Self>

where Self: Sized,

Multiplies the seed by value.

impl OpenSimplexNoise for OpenSimplex2

fn improve2_x(self) -> Improve2X<Self>

where Self: Sized,

Improves 2D orientation with Y pointing down the main diagonal.

fn improve3_xy(self) -> Improve3Xy<Self>

where Self: Sized,

Improves 3D orientation for better visual isotropy in (X, Y).

fn improve3_xz(self) -> Improve3Xz<Self>

where Self: Sized,

Improves 3D orientation for better visual isotropy in (X, Z).

fn improve4_xyz(self) -> Improve4Xyz<Self>

where Self: Sized,

Improves 4D orientation so XYZ is oriented like the default 3D noise and W for an extra degree of freedom. W repeats eventually.

fn improve4_xyz_xy(self) -> Improve4XyzXy<Self>

where Self: Sized,

Improves 4D orientation so XYZ is oriented like the 3D improve_xy noise and W for an extra degree of freedom. W repeats eventually.

fn improve4_xyz_xz(self) -> Improve4XyzXz<Self>

where Self: Sized,

Improves 4D orientation so XYZ is oriented like the 3D improve_xz noise and W for an extra degree of freedom. W repeats eventually.

fn improve4_xy_zw(self) -> Improve4XyZw<Self>

where Self: Sized,

Improves 4D orientation so XY and ZW form orthogonal triangular-based planes.

impl PartialEq for OpenSimplex2

fn eq(&self, other: &OpenSimplex2) -> 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.
