I found an issue in the Chinese version of the 11 chapter, in the 2D Noise section. #434

Description

@weijiewow

Origin

Now that we know how to do noise in 1D, it's time to move on to 2D. In 2D, instead of interpolating between two points of a line (rand(x) and rand(x)+1.0), we are going to interpolate between the four corners of the square area of a plane (rand(st), rand(st)+vec2(1.,0.), rand(st)+vec2(0.,1.) and rand(st)+vec2(1.,1.)).

Chinese

现在我们知道了如何在一维使用 noise,是时候进入二维世界了。在 2D 中,除了在一条线的两点(fract(x) 和 fract(x)+1.0)中插值,我们将在一个平面上的方形的四角(fract(st), fract(st)+vec2(1.,0.), fract(st)+vec2(0.,1.) 和 fract(st)+vec2(1.,1.))中插值。

Issue

The 'fract' in Chinese version should be 'rand'.
