Constructors

constructor

new Noise(seed?): Noise
构建柏林噪音
Parameters
- Optional seed: number
  
  随机种子
Returns Noise
- Defined in node_modules/@feng3d/math/lib/Noise.d.ts:16

Properties

`Private` _p

_p: any

`Private` _seed

_seed: any

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 node_modules/@feng3d/math/lib/Noise.d.ts:55
set seed(v): void
Parameters
- v: number
Returns void
- Defined in node_modules/@feng3d/math/lib/Noise.d.ts:56

Methods

perlin1

perlin1(x): number
1D 经典噪音
Parameters
- x: number
  
  X轴数值
Returns number
- Defined in node_modules/@feng3d/math/lib/Noise.d.ts:22

perlin2

perlin2(x, y): number
2D 经典噪音
Parameters
- x: number
  
  X轴数值
- y: number
  
  Y轴数值
Returns number
- Defined in node_modules/@feng3d/math/lib/Noise.d.ts:29

perlin3

perlin3(x, y, z): 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 node_modules/@feng3d/math/lib/Noise.d.ts:37

perlinN

perlinN(...ps): 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 node_modules/@feng3d/math/lib/Noise.d.ts:50
