API reference / @jsprismarine/worldgen / SimplexNoise

Class: SimplexNoise

Defined in: noise/SimplexNoise.ts:17

Simplex noise, which Java Edition uses only for the outer end islands.

Unlike Perlin noise, the corner contributions are computed in double precision and only the result narrows to float.

Constructors

Constructor

new SimplexNoise(random, discardNoiseOffset?): SimplexNoise

Defined in: noise/SimplexNoise.ts:25

Parameters

random

RandomSource

discardNoiseOffset?

boolean = false

When true the three random coordinate offsets are drawn but scaled to zero, which is how the end island generator seeds its instance.

Returns

SimplexNoise

Overrides

GradientNoise.constructor

Properties

offsetX

readonly offsetX: number

Defined in: noise/GradientNoise.ts:58

The random offset applied to the x coordinate before lookup.

Inherited from

GradientNoise.offsetX

---

offsetY

readonly offsetY: number

Defined in: noise/GradientNoise.ts:60

The random offset applied to the y coordinate before lookup.

Inherited from

GradientNoise.offsetY

---

offsetZ

readonly offsetZ: number

Defined in: noise/GradientNoise.ts:62

The random offset applied to the z coordinate before lookup.

Inherited from

GradientNoise.offsetZ

STANDARD_DEVIATION

readonly static STANDARD_DEVIATION: 0.42544 = 0.42544

Defined in: noise/SimplexNoise.ts:19

The standard deviation of one simplex octave.

Methods
