Struct PerlinNoise 

pub struct PerlinNoise {
    pub persistence: f32,
    pub octaves: f32,
    pub seed_x: i32,
    pub seed_y: i32,
}

A noise field: its persistence, octaves and two seeds.

Fields

persistence: f32

How much each octave adds: octave i is scaled by persistence to the power i.

octaves: f32

The number of octaves. The loop runs while (float)i < octaves.

seed_x: i32

The first seed of the hash.

seed_y: i32

The second seed of the hash.

Implementations

impl PerlinNoise

pub fn new(persistence: f32, octaves: f32, seed_x: i32, seed_y: i32) -> Self

A noise field with these settings.

Original: PerlinNoise(float, float, int, int), Runtime 0x18010b500.

pub fn random(&self, x: i32, y: i32) -> f32

The hashed value at an integer point, from -1 to 1.

Original: Random(int, int), Runtime 0x18010ad80.

pub fn smooth_noise(&self, x: i32, y: i32) -> f32

The value at an integer point, smoothed with its 8 neighbours: corners / 16 + edges / 8 + centre / 4, added in the original’s order.

Original: SmoothNoise(int, int), Runtime 0x18010ae50.

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

The noise at a point: every octave, interpolated and added.

Original: Generate(float, float), Runtime 0x18010b240.
