def gaussian_noise(length, mean=0, std_dev=1): return np.random.normal(mean, std_dev, length) ``` 这个函数使用`np.random.normal(`生成服从正态分布(高斯分布)的随机数。 3. 波动噪声函数(Perlin Noise Function)是一种自相关的、平滑的随机函数。它可以用来生成连续的、看起来有层次感的随机图案。
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 a frequency to be displayable. There simply may not be enough pixels on the screen ...

This is the function for adding perlin noise to the depth map. It is a simplified implementation of the paper: an image sunthesizer Ken Perlin, SIGGRAPH, Jul. 1985 The bicubic interpolation is used, compared to the original version.
Set the seed of Perlin noise. noise(x, [y], [z]) Return the Perlin noise value for the specified coordinates. Image Class width,height The width and height of the image set(x, y, data) Set the image at (x,y) using a list of strings. ...

Description: This approach uses Perlin noise to generate a terrain-like heightmap, which is then converted into a maze by thresholding. Mechanism: Perlin noise, a type of gradient noise, is used to create a smooth and continuous terrain heightmap. The grid is then divided into passable and ...
