写这篇文章的初衷,作者最近在使用Matlab中的Genetic Algorithm时,在设置Initial Population Matrix时需要一维的Perlin Noise,但是在网上没有搜到相对应的代码(白嫖失败),在Mathwork里也没有搜到自带的Perlin Noise function,找到了一个带有2D和3D Perlin Noise的库,但是没有找到可以生成1D Perlin Noise(如果有谁找到了...
Where i is the ithnoise function being added. To illustrate the effect of persistence on the output of the Perlin Noise, take a look at the diagrams below. They show the component noise functions that are added, the effect of the persistence value, and the resultant Perlin noise function. ...
Exactly how many octaves you add together is entirely up to you. You may add as many or as few as you want. However, let me give you some suggestions. If you are using the perlin noise function to render an image to the screen, there will come a point when an octave has too high...

Two deficiencies in the original Noise algorithm are corrected: second order interpolation discontinuity and unoptimal gradient computation. With these defects corrected, Noise both looks better and runs faster. The latter change also makes it easier to define a uniform mathematical reference standard. ...
