1、这是其中一种噪音的代码：
pixels = W:1024 H:1024
x = from 0 to 512 H
y = from 0 to 512 W
k = mod(x+y+mod(208.0+x*3.58,13.0+mod(y*22.9, 9.0)),7.0)*0.143
r = k
g = k
b = k
说到底，就是k在起作用。
2、修改k后面的代码，就可以改变噪音的样式：
k = mod(x+y+mod(0.6+x*0.36,13.0+mod(y*22.9, 9.0)),7.0)*0.143
3、如果k = mod(x+y+mod(0.6+x*0.36,13.0+mod(y*22.9, 9.0)),7.0)*0.36，得到的图形如下。
4、改变一下代码：
pixels = W:1024 H:1024
x = from 0 to 512 H
y = from 0 to 512 W
k = mod(x+y+mod(0.6+x*3.6,2+mod(y*36, 9.0)),7.0)*0.36
r = k
g =2* k
b = k
5、k = mod(x+y+mod(0.6+x*3.6,2+mod(y*36, 36)),7.0)*0.36对应的图像如下。
6、换一个新的代码：
pixels = W:1024 H:1024
x = from 0 to 512 H
y = from 0 to 512 W
k = mod(x+y+mod(0.6+x*3.6,36+mod(y*36, 36)),7.0)*0.36
r =sin(3.6*k)
g =sin(2*k)
b =sin(k)
