要绘制3D图形,可以使用Matplotlib中的mplot3d模块。以下是一个简单的示例,展示如何绘制一个立方体:
import matplotlib.pyplot as plt from mpl_toolkits.mplot3d import Axes3D fig = plt.figure() ax = fig.add_subplot(111, projection='3d') # 定义立方体的顶点 vertices = [ [0, 0, 0], [1, 0, 0], [1, 1, 0], [0, 1, 0], [0, 0, 1], [1, 0, 1], [1, 1, 1], [0, 1, 1] ] # 定义立方体的面 faces = [ [vertices[0], vertices[1], vertices[2], vertices[3]], [vertices[4], vertices[5], vertices[6], vertices[7]], [vertices[0], vertices[1], vertices[5], vertices[4]], [vertices[2], vertices[3], vertices[7], vertices[6]], [vertices[1], vertices[2], vertices[6], vertices[5]], [vertices[4], vertices[7], vertices[3], vertices[0]] ] # 绘制立方体的面 for face in faces: x = [vertex[0] for vertex in face] y = [vertex[1] for vertex in face] z = [vertex[2] for vertex in face] ax.plot(x, y, z) plt.show()
运行以上代码即可绘制一个简单的立方体。您也可以根据需要调整顶点和面的位置,以绘制不同的3D图形。
