python3D爱心代码

以下是Python实现的3D爱心代码：

import math

def heart_3d(x, y, z):
    return (x**2 + 9/4*y**2 + z**2 - 1)**3 - x**2*z**3 - 9/80*y**2*z**3

def print_heart_3d():
    scale = 0.02
    for y in range(30, -30, -1):
        line = ""
        for x in range(-30, 30):
            z = heart_3d(x*scale, y*scale, 0)*scale
            if z <= 0:
                line += "*"
            else:
                line += " "
        print(line)

print_heart_3d()
