使用三维体形状画一些创意梯形图形的代码

以下是使用Python中的Matplotlib库绘制三维梯形图形的示例代码：

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d.art3d import Poly3DCollection

# 输入梯形的参数
bottom_width = 2
top_width = 4
height = 4
depth = 1

# 定义梯形的8个顶点坐标
v1 = [0, 0, 0]
v2 = [bottom_width, 0, 0]
v3 = [bottom_width, height, 0]
v4 = [0, height, 0]
v5 = [0 + (top_width - bottom_width)/2, 0 + (top_width - bottom_width)/2, depth]
v6 = [bottom_width - (top_width - bottom_width)/2, 0 + (top_width - bottom_width)/2, depth]
v7 = [bottom_width - (top_width - bottom_width)/2, height - (top_width - bottom_width)/2, depth]
v8 = [0 + (top_width - bottom_width)/2, height - (top_width - bottom_width)/2, depth]

# 定义梯形的6个面
verts = [ [v1,v2,v3,v4], [v1,v2,v6,v5], [v2,v3,v7,v6], [v3,v4,v8,v7], [v4,v1,v5,v8], [v5,v6,v7,v8] ]

# 绘制图形
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 添加梯形面
poly3d = Poly3DCollection(verts, alpha=.25, facecolor='g')
ax.add_collection3d(poly3d)

# 设置坐标轴范围
ax.set_xlim([0, top_width])
ax.set_ylim([0, height])
ax.set_zlim([0, depth])

# 添加坐标轴标签
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')

# 显示图形
plt.show()

运行代码后，将会绘制出一个三维梯形图形，如下所示：
