使用plotly绘制3D凸包

import plotly.graph_objects as go
import numpy as np
from scipy.spatial import ConvexHull

# 创建随机数据集
np.random.seed(0)
points = np.random.randn(30, 3)

hull = ConvexHull(points)

fig = go.Figure(data=[go.Scatter3d(x=points[:,0], y=points[:,1], z=points[:,2], mode='markers')])

# 绘制凸包的每个面
for i in hull.simplices:
    x = points[i, 0]
    y = points[i, 1]
    z = points[i, 2]
    x = np.append(x, x[0])  # 闭合凸包
    y = np.append(y, y[0])
    z = np.append(z, z[0])
    fig.add_trace(go.Mesh3d(x=x, y=y, z=z, color='lightpink', opacity=0.5))

# 设置图形布局
fig.update_layout(scene=dict(aspectratio=dict(x=1, y=1, z=1),
                             xaxis=dict(title='X'),
                             yaxis=dict(title='Y'),
                             zaxis=dict(title='Z')))

# 显示图形
fig.show()
