基于python的processing代码，做一个山脉

以下是一个基于Python的Processing代码，可以绘制出一座山脉：

import random
import noise
import math
from processing import *

# 设置画布大小
size(800, 600)

# 设置山脉的宽度和高度
width = 800
height = 600

# 设置山脉的细节
scale = 100.0
octaves = 6
persistence = 0.5
lacunarity = 2.0

# 生成山脉的噪声图
def generate_noise_map(width, height, scale, octaves, persistence, lacunarity):
    noise_map = [[0 for y in range(height)] for x in range(width)]
    for x in range(width):
        for y in range(height):
            amplitude = 1
            frequency = 1
            noise_height = 0
            for i in range(octaves):
                sample_x = x / scale * frequency
                sample_y = y / scale * frequency
                perlin_value = noise.pnoise2(sample_x, sample_y, octaves=i, persistence=persistence, lacunarity=lacunarity)
                noise_height += perlin_value * amplitude
                amplitude *= persistence
                frequency *= lacunarity
            noise_map[x][y] = noise_height
    return noise_map

# 绘制山脉
def draw_mountain():
    noise_map = generate_noise_map(width, height, scale, octaves, persistence, lacunarity)
    for x in range(width):
        for y in range(height):
            point = noise_map[x][y]
            color = lerpColor(color(51, 51, 204), color(255, 255, 255), point)
            stroke(color)
            point = map(point, -1, 1, 0, height)
            point = math.floor(point)
            point = constrain(point, 0, height - 1)
            point(x, point, x, height)

# 调用绘制函数
draw_mountain()

这段代码使用了Python的Processing库来绘制山脉。它使用Perlin噪声算法来生成山脉，并使用lerpColor函数来渐变颜色。你可以通过调整参数来改变山脉的形状和大小。
