写一段代码python生成3D爱心

以下是Python代码，可以生成3D爱心：

import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

theta = np.linspace(0, 2*np.pi, 100)
phi = np.linspace(0, np.pi, 100)
theta, phi = np.meshgrid(theta, phi)

a = 1
b = 1
c = 1

x = a*np.sin(phi)*np.cos(theta)
y = b*np.sin(phi)*np.sin(theta)
z = c*np.cos(phi)

r = np.sqrt(x**2 + y**2 + z**2)
heart = (r**2 + z**2 - a**2)**3 - (a**2)*z**2*r**3

ax.plot_surface(x, y, z, rstride=1, cstride=1, facecolors=plt.cm.jet(heart/heart.max()))
ax.set_axis_off()

plt.show()

这段代码使用了numpy和matplotlib库，生成了一个3D的爱心图形。
