Struct SpatialHash 

pub struct SpatialHash { /* private fields */ }

Spatial hash for 2D blue noise-like properties.

Uses coordinate hashing to create spatially decorrelated noise. Provides blue noise-like characteristics without lookup tables. Good balance between quality and memory efficiency.

Implementations

impl SpatialHash

pub fn new(seed: u32) -> Self

Trait Implementations

impl Clone for SpatialHash

fn clone(&self) -> SpatialHash

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SpatialHash

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

Formats the value using the given formatter.

impl Hash for SpatialHash

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SpatialHash

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

impl SpatialRng for SpatialHash

fn new(seed: u32) -> Self

Create a new spatial RNG with the given seed.

fn compute(&self, x: u32, y: u32) -> f32

Compute a deterministic value for given 2D coordinates. Returns a value in range [-1, 1].

fn dither_2d<T>( &self, value: T, min: T, one: T, dither_amplitude: T, x: u32, y: u32, ) -> T

where T: DitherFloat, Self: Sized,

Dither a single value using 2D coordinates.

fn simple_dither_2d<T>(&self, value: T, one: T, x: u32, y: u32) -> T

where T: DitherFloat + Number + CastableFrom<f32>, Self: Sized,

Simple dither for a single value using 2D coordinates.

fn dither_slice_2d<T>( &self, values: &mut [T], width: usize, min: T, one: T, dither_amplitude: T, )

where T: DitherFloat + Send + Sync, Self: Sized,

Dither a 2D image stored as a flat slice (parallel version).

fn simple_dither_slice_2d<T>(&self, values: &mut [T], width: usize, one: T)

where T: DitherFloat + Number + CastableFrom<f32> + Send + Sync, Self: Sized,

Simple dither for a 2D image stored as a flat slice (parallel version).

fn dither_float_2d<Src, Dest>(&self, value: Src, x: u32, y: u32) -> Dest

where Src: DitherFloatConversion<Dest> + DitherFloat + CastableFrom<f64>, Self: Sized,

Dither a float value when converting to lower precision using 2D coordinates.

fn dither_float_slice_2d<Src, Dest>( &self, values: &[Src], width: usize, ) -> Vec<Dest>

where Src: DitherFloatConversion<Dest> + DitherFloat + CastableFrom<f64> + Copy + Send + Sync, Dest: Send, Self: Sized,

Dither float values in a 2D image slice when converting to lower precision (parallel version).
