Struct noise::Seed

pub struct Seed {
    // some fields omitted
}

A seed table, required by all noise functions.

Table creation is expensive, so in most circumstances you'll only want to create one of these and reuse it everywhere.

Methods

impl Seed

fn new(seed: u32) -> Seed

Deterministically generates a new seed table based on a u32 value.

Internally this uses a XorShiftRng, but we don't really need to worry about cryptographic security when working with procedural noise.

Example

use noise::Seed;

let seed = Seed::new(12);

fn get1<T: Signed + PrimInt + NumCast>(&self, x: T) -> usize

fn get2<T: Signed + PrimInt + NumCast>(&self, pos: Point2<T>) -> usize

fn get3<T: Signed + PrimInt + NumCast>(&self, pos: Point3<T>) -> usize

fn get4<T: Signed + PrimInt + NumCast>(&self, pos: Point4<T>) -> usize

Trait Implementations

impl Rand for Seed

fn rand<R: Rng>(rng: &mut R) -> Seed

Generates a random seed.

Examples

extern crate noise;
extern crate rand;

use noise::Seed;

let seed = rand::random::<Seed>();

extern crate noise;
extern crate rand;

use noise::Seed;
use rand::{SeedableRng, Rng, XorShiftRng};

let mut rng: XorShiftRng = SeedableRng::from_seed([1, 2, 3, 4]);
let seed = rng.gen::<Seed>();
