python中怎么使3D散点图的点为五角星

在Python中，可以使用matplotlib库结合numpy数组和patch模块来创建3D散点图，并且将这些点呈现为五角星。以下是一个简单的示例：

import matplotlib.pyplot as plt
from mpl_toolkits.mplot3d import Axes3D
import numpy as np

# 创建数据
n = 50
u = np.linspace(0, 2 * np.pi, n)
v = np.linspace(0, np.pi, n)
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))

# 创建3D图形并添加一个轴
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 创建五角星数据
points = [[-1, -1, 0], [1, -1, 0], [1, 1, 0], [-1, 1, 0], [-1, -1, 0]]  # 五角星的顶点
star_points = [(x + y + z) * p for x, y, z in zip(x.flatten(), y.flatten(), z.flatten()) for p in points]

# 绘制3D散点和五角星
ax.scatter(x.flatten(), y.flatten(), z.flatten(), c=z.flatten(), cmap='viridis', s=100, alpha=0.8)
ax.scatter(star_points[:, 0], star_points[:, 1], star_points[:, 2], color='red', marker='*', s=200)

# 设置轴标签和标题
ax.set_xlabel('X')
ax.set_ylabel('Y')
ax.set_zlabel('Z')
ax.set_title('3D Scatter Plot with Star Points')

plt.show()
