Implementations

impl NormalNoise

pub fn create( splitter: &RandomSplitter, noise_id: &str, first_octave: i32, amplitudes: &[f64], ) -> NormalNoise

Creates parity noise from a positional worldgen splitter.

pub fn create_from_random( random: &mut RandomSource, first_octave: i32, amplitudes: &[f64], ) -> NormalNoise

Creates parity noise from a vanilla random source.

pub fn create_legacy_nether_biome( random: &mut RandomSource, first_octave: i32, amplitudes: &[f64], ) -> NormalNoise

Creates the legacy-Nether variant, whose octave sources are sequentially seeded.

Panics

Panics if no octaves are provided or a positive octave is requested.

pub fn create_with_params( splitter: &RandomSplitter, noise_id: &str, base_octave: i32, base_amplitude: f64, octave_count: i32, normalize: bool, amplitude_modifiers: &[f64], ) -> NormalNoise

Creates current datapack noise from a positional worldgen splitter.

pub fn create_from_random_with_params( random: &mut RandomSource, base_octave: i32, base_amplitude: f64, octave_count: i32, normalize: bool, amplitude_modifiers: &[f64], ) -> NormalNoise

Creates current datapack noise from a vanilla random source.

pub fn get_value(&self, x: f64, y: f64, z: f64) -> f32

Samples the float-valued vanilla noise stack.

pub fn get_value_xz(&self, x: f64, z: f64) -> f32

Samples the float-valued vanilla noise stack with a fixed Y coordinate.

pub fn get_value_xy(&self, x: f64, y: f64) -> f32

Samples the float-valued vanilla noise stack with a fixed Z coordinate.

pub fn get_value_y_simd<const N: usize>( &self, x: f64, ys: Simd<f64, N>, z: f64, ) -> Simd<f32, N>

Samples a SIMD Y column with the same f32 accumulator as get_value.

pub const fn max_value(&self) -> f64

Returns the vanilla sampler’s conservative range bound.

Trait Implementations
