模拟“噪音”环境——图像噪音

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)
