# 三维曲面(纯色)
|
|
|
|
使用纯色演示3D表面的基本图。
|
|
|
|
|
|
|
|
```python
|
|
# This import registers the 3D projection, but is otherwise unused.
|
|
from mpl_toolkits.mplot3d import Axes3D # noqa: F401 unused import
|
|
|
|
import matplotlib.pyplot as plt
|
|
import numpy as np
|
|
|
|
|
|
fig = plt.figure()
|
|
ax = fig.add_subplot(111, projection='3d')
|
|
|
|
# Make data
|
|
u = np.linspace(0, 2 * np.pi, 100)
|
|
v = np.linspace(0, np.pi, 100)
|
|
x = 10 * np.outer(np.cos(u), np.sin(v))
|
|
y = 10 * np.outer(np.sin(u), np.sin(v))
|
|
z = 10 * np.outer(np.ones(np.size(u)), np.cos(v))
|
|
|
|
# Plot the surface
|
|
ax.plot_surface(x, y, z, color='b')
|
|
|
|
plt.show()
|
|
```
