Python使用matplotlib绘制圆形代码实例
可以使用matplotlib库来实现,请先确保已经成功安装该库。下面是绘制圆面的Python代码:
```
import numpy as np
import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
# 圆心位置
x0, y0, z0 = 0, 0, 0
# 圆面半径
r = 1
# 定义圆面上的网格点
u, v = np.mgrid[0:2*np.pi:20j, 0:np.pi:10j]
# 计算每个点的三维坐标
x = x0 + r * np.cos(u) * np.sin(v)
y = y0 + r * np.sin(u) * np.sin(v)
z = z0 + r * np.cos(v)
# 创建三维坐标轴
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
# 绘制圆面
ax.plot_surface(x, y, z, color='b')
# 设置坐标轴范围
max_range = np.array([x.max()-x.min(), y.max()-y.min(), z.max()-z.min()]).max()
X, Y, Z = 0.5 * max_range * np.mgrid[-1:2:2, -1:2:2, -1:2:2]
ax.set_xlim([-1,1])
ax.set_ylim([-1,1])
ax.set_zlim([-1,1])
# 显示图像
plt.show()
```
运行结果:
