这个函数的问题在于它没有使用传入的参数edges、origin、alpha和color,而是在函数内部使用了硬编码的值。下面是修改后的代码:
```python
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.patches import Patch
from mpl_toolkits.mplot3d.art3d import Patch3DCollection
def plot_cube(edges=[10, 56, 100], origin=[10, 10, 10], alpha=0.7, color=[1, 0, 0]):
# 构建立方体6个面片的XYZ坐标矩阵XYZ。每个面片4个顶点的坐标由edges和origin计算得到
XYZ = [
[[0, 0, 0], [0, 0, 1], [0, 1, 1], [0, 1, 0]], # front
[[1, 1, 1], [0, 0, 1], [0, 1, 1], [1, 1, 0]], # back
[[0, 1, 1], [0, 0, 0], [0, 0, 1], [0, 1, 0]], # left
[[0, 1, 1], [1, 1, 1], [0, 0, 1], [1, 1, 0]], # right
[[0, 1, 1], [0, 0, 1], [0, 0, 0], [0, 1, 0]], # bottom
[[0, 1, 1], [0, 0, 1], [1, 1, 1], [1, 1, 0]] # top
]
# 使用Patch绘制立方体6个面片
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
faces = [
Patch(color=color), # front
Patch(color=color), # back
Patch(color=color), # left
Patch(color=color), # right
Patch(color=color), # bottom
Patch(color=color) # top
]
for i in range(6):
x = XYZ[i][0] * int(edges[0]) + origin[0]
y = XYZ[i][1] * int(edges[1]) + origin[1]
z = XYZ[i][2] * int(edges[2]) + origin[2]
ax.add_collection3d(Patch3DCollection([faces[i]], zs=z, zdir='z', alpha=alpha))
# 设置视角为3D视角
ax.view_init(70, 75)
plt.show()
```
现在,这个函数可以使用传入的参数来画一个指定大小、位置、透明度和颜色的立方体了。
