使用Python和matplotlib库
```python
import matplotlib.pyplot as plt
import numpy as np
定义心形曲线的参数方程
def heart_curve(t):
x = 16 * np.sin(t) 3
y = 13 * np.cos(t) - 5 * np.cos(2 * t) - 2 * np.cos(3 * t) - np.cos(4 * t)
return x, y
生成参数t的值
theta = np.linspace(0, 2 * np.pi, 1000)
r = 1 - np.sin(theta)
绘制心形曲线
plt.polar(theta, r)
plt.show()
```
使用Python和turtle库
```python
import turtle
创建画布
screen = turtle.Screen()
pen = turtle.Turtle()
绘制心形图案
pen.circle(50, 180)
pen.circle(-50, 180)
pen.setheading(90)
pen.circle(50, 90)
pen.circle(-50, 90)
pen.setheading(0)
pen.forward(100)
pen.left(90)
pen.circle(-50, 90)
pen.circle(50, 90)
pen.left(90)
pen.forward(100)
关闭画布
screen.exitonclick()
```
使用C语言和图形库
```c
include
int main() {
int x, y, a;
float t;
// 初始化图形窗口
initgraph(640, 480);
// 绘制心形曲线
for (y = 1.5; y >= -1.5; y -= 0.1) {
for (x = -1.5; x <= 1.5; x += 0.05) {
t = x * x + y * y - 1;
if (t <= 0) {
t = -(t * t * t - x * x * y * y * y) * -8.0;
putpixel(x + 320, y + 240, 255);
}
}
}
// 刷新图形窗口
getch();
closegraph();
return 0;
}
```
使用Java和Swing
