產生 3D 多邊形#
示範如何在 3D 中建立多邊形。在這裡，我們堆疊 3 個六邊形。
import matplotlib.pyplot as plt
import numpy as np
from mpl_toolkits.mplot3d.art3d import Poly3DCollection
# Coordinates of a hexagon
angles = np.linspace(0, 2 * np.pi, 6, endpoint=False)
x = np.cos(angles)
y = np.sin(angles)
zs = [-3, -2, -1]
# Close the hexagon by repeating the first vertex
x = np.append(x, x[0])
y = np.append(y, y[0])
verts = []
for z in zs:
verts.append(list(zip(x*z, y*z, np.full_like(x, z))))
verts = np.array(verts)
ax = plt.figure().add_subplot(projection='3d')
poly = Poly3DCollection(verts, alpha=.7)
ax.add_collection3d(poly)
ax.set_aspect('equalxy')
plt.show()
