python画个三维喷气无人机

要画一个三维喷气无人机，我们可以使用Python中的Matplotlib库和mpl_toolkits库中的mplot3d模块。

下面是一个简单的例子代码，可以绘制一个基本的三维喷气无人机模型：

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

fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')

# 坐标轴范围
ax.set_xlim(-1, 1)
ax.set_ylim(-1, 1)
ax.set_zlim(-1, 1)

# 机身
x, y, z = np.linspace(-0.5, 0.5, 10), np.linspace(-0.5, 0.5, 10), np.linspace(-0.5, 0.5, 10)
X, Y = np.meshgrid(x, y)
Z = np.zeros_like(X)
Z[0,:] = z[0]
Z[-1,:] = z[-1]
Z[:,0] = z[:,0]
Z[:,-1] = z[:,-1]
ax.plot_surface(X, Y, Z, color='gray')

# 机翼
wing_x, wing_y = np.linspace(-0.5, 0.5, 5), np.linspace(-0.3, 0.3, 5)
WING_X, WING_Y = np.meshgrid(wing_x, wing_y)
WING_Z = np.zeros_like(WING_X)
WING_Z[0,:] = z[0]
WING_Z[-1,:] = z[-1]
WING_Z[:,0] = z[:,0]
WING_Z[:,-1] = z[:,-1]
WING_Z += 0.2
ax.plot_surface(WING_X, WING_Y, WING_Z, color='gray')

# 引擎喷口
NOZZLE_X, NOZZLE_Y, NOZZLE_Z = np.meshgrid([-0.2, 0.2], [-0.2, 0.2], [0, 0.1])
ax.plot_surface(NOZZLE_X, NOZZLE_Y, NOZZLE_Z, color='red')

plt.show()

这个代码使用了numpy中的linspace函数来生成坐标轴上的点，然后使用meshgrid函数生成网格点，最后使用plot_surface函数绘制三维图形。
