Constructors

constructor

new Noise(seed?: number): Noise
构建柏林噪音
Parameters
- seed: number = 0
  
  随机种子
Returns Noise
- Defined in src/math/Noise.ts:17

Properties

`Private` _p

_p: number[] = []

`Private` _seed

_seed: number = 0

Accessors

seed

get seed(): number
This isn't a very good seeding function, but it works ok. It supports 2^16 different seed values. Write something better if you need more seeds.

Returns number
- Defined in src/math/Noise.ts:266
set seed(v: number): void
Parameters
- v: number
Returns void
- Defined in src/math/Noise.ts:270

Methods

perlin1

perlin1(x: number): number
1D 经典噪音
Parameters
- x: number
  
  X轴数值
Returns number
- Defined in src/math/Noise.ts:27

perlin2

perlin2(x: number, y: number): number
2D 经典噪音
Parameters
- x: number
  
  X轴数值
- y: number
  
  Y轴数值
Returns number
- Defined in src/math/Noise.ts:60

perlin3

perlin3(x: number, y: number, z: number): number
3D 经典噪音
Parameters
- x: number
  
  X轴数值
- y: number
  
  Y轴数值
- z: number
  
  Z轴数值
Returns number
- Defined in src/math/Noise.ts:105

perlinN

perlinN(...ps: number[]): number
N阶经典噪音

如果是1D，2D，3D噪音，最好选用对于函数，perlinN中存在for循环因此效率比perlin3等性能差3到5（8）倍！

满足以下运算 perlinN(x) === perlin1(x) perlinN(x,y) === perlin2(x,y) perlinN(x,y,z) === perlin3(x,y,z)
Parameters
- Rest ...ps: number[]
  
  每个轴的数值
Returns number
- Defined in src/math/Noise.ts:172
