Question

我一直在研究python中的terrin生成器，该生成器应该生成高度图。我希望它看起来像this。

上面所说的代码如何产生类似于this的结果。我想知道是否有人能告诉我代码为什么会产生奇数对角线，因为我一生无法弄清楚它...

import random as rand
from PIL import Image



class QuickMap(object):
    def __init__(self, x, y):
        self.size = (x, y)
        self.randomNoise = [[0 for cl in range(self.size[1])] for rw in range(self.size[0])]
        self.cNoise = [[0 for cl in range(self.size[1])] for rw in range(self.size[0])]

    def makeStart(self, init_num, scale):
        for i in range(init_num):
            randPos = (rand.randint(1, self.size[0]-1), rand.randint(1, self.size[1]-1))
            self.randomNoise[randPos[0]][randPos[1]] = rand.randrange(0, scale)
            self.cNoise[randPos[0]][randPos[1]] = self.randomNoise[randPos[0]][randPos[1]]

    def gen_map(self, scale, pascle):
        for rw in range(1, self.size[0]-1):
            for cl in range(1, self.size[1]-1):
                for x in range(-1, 2):
                    for y in range(-1, 2):
                        if self.randomNoise[rw+x][cl+y] < self.randomNoise[rw][cl]:
                            if float(self.randomNoise[rw+y][cl+x]).is_integer():
                                randVar = rand.randint(1, 10)
                                if randVar % 2 == 1:
                                    self.randomNoise[rw+y][cl+x] = (self.randomNoise[rw][cl] - 3)
                #print('\n\n\n\n\n')

        for rw in range(0, self.size[0]):
            for cl in range(0, self.size[1]):
                self.cNoise[rw][cl] = self.randomNoise[rw][cl]



    def smooth(self, smoothing_itterations, scale):
        pscale = scale
        self.gen_map(scale, pscale)
        for i in range(smoothing_itterations):
            for rw in range(self.size[0]):
                for cl in range(self.size[1]):
                    self.randomNoise[rw][cl] = self.cNoise[rw][cl]
            self.cNoise = [[0 for cl in range(self.size[1])] for rw in range(self.size[0])]

            scale -= 3
            self.gen_map(scale, pscale)
            print(i/smoothing_itterations)



    def make_picture(self):
        img = Image.new('L', (self.size[0], self.size[1]))
        dataToWrite = [[0 for cl in range(self.size[1])] for rw in range(self.size[0])]
        for rw in range(self.size[0]):
            for cl in range(self.size[1]):
                dataToWrite[rw][cl] = self.cNoise[rw][cl] % 256
        for rw in range(self.size[0]):
            for cl in range(self.size[1]):
                img.putpixel((rw, cl), int(dataToWrite[rw][cl]))
        img.save('Output.png')


qm = QuickMap(100, 100)
qm.makeStart(16, 256)
qm.smooth(0, 256)
qm.make_picture()

谢谢！

为什么这段代码会产生奇数对角条纹
