Merry Xmas | 用Matplotlib画个3D圣诞树送给你！~

1写在前面

Merry Christmas !

过完圣诞就要跨年了，希望2023年自己可以一扫霉运，顺顺利利！！！

从网上抄了个英文的祝福语送给大家（主要是懒）:

I hope Santa is good to you this year because you only deserve the best.

今天就用python的matplotlib给大家画个圣诞树吧。

2用到的包

import math
import matplotlib.pyplot as plt
from matplotlib import animation
from mpl_toolkits.mplot3d import Axes3D

3画个圣诞树

fig = plt.figure(figsize=(8,8))
ax = fig.add_subplot(111, projection="3d")
def init():
    k=300
    Z = [i for i in range(k)]
    X = [math.cos(i/5)*(k-i) for i in range(k)]
    Y = [math.sin(i/5)*(k-i) for i in range(k)]
    ax.scatter(X,Y,Z, c="green", marker="^")
    step = 3
    c = [(i/k,abs(0.5-i/k),i/k) for i in range(1,k,step)]
    Z = [i for i in range(1,k,step)]
    X = [math.cos(i/5+2)*(k-i+10) for i in range(1,k,step)]
    Y = [math.sin(i/5+2)*(k-i+10) for i in range(1,k,step)]
    ax.scatter(X,Y,Z, c=c, marker="o",s=40)
    plt.xlim(-500,500)
    plt.ylim(-500,500)
    return fig,
def animate(f):
    fig.clear()
    ax = fig.add_subplot(111, projection="3d")
    k=300
    Z = [i for i in range(k)]
    X = [math.cos(i/5+f/10)*(k-i) for i in range(k)]
    Y = [math.sin(i/5+f/10)*(k-i) for i in range(k)]
    ax.scatter(X,Y,Z, c="green", marker="^")
    step = 3
    c = [(i/k,abs(0.5-i/k),i/k) for i in range(1,k,step)]
    Z = [i for i in range(1,k,step)]
    X = [math.cos(i/5+2+f/10)*(k-i+10) for i in range(1,k,step)]
    Y = [math.sin(i/5+2+f/10)*(k-i+10) for i in range(1,k,step)]
    ax.scatter(X,Y,Z, c=c, marker="o",s=40)
    plt.xlim(-500,500)
    plt.ylim(-500,500)
    return fig,
ani=animation.FuncAnimation(fig, animate, init_func=init,
                               frames=90, interval=50, blit=True)

Note! 是有动画的哦，这里就不展示了，大家有兴趣试一下。

最后祝大家圣诞快乐!~
