它有点复杂,但您可以通过以下代码绘制所有对象:from mpl_toolkits.mplot3d import Axes3Dimport matplotlib.pyplot as pltimport numpy as npfrom itertools import product, combinationsfig = plt.figure()ax = fig.gca(projection='3d')ax.set_aspect("equal")# draw cuber = [-1, 1]for s, e in combinations(np.array(list(product(r, r, r))), 2): if np.sum(np.abs(s-e)) == r[1]-r[0]: ax.plot3D(*zip(s, e), color="b")# draw sphereu, v = np.mgrid[0:2*np.pi:20j, 0:np.pi:10j]x = np.cos(u)*np.sin(v)y = np.sin(u)*np.sin(v)z = np.cos(v)ax.plot_wireframe(x, y, z, color="r")# draw a pointax.scatter([0], [0], [0], color="g", s=100)# draw a vectorfrom matplotlib.patches import FancyArrowPatchfrom mpl_toolkits.mplot3d import proj3dclass Arrow3D(FancyArrowPatch): def __init__(self, xs, ys, zs, *args, **kwargs): FancyArrowPatch.__init__(self, (0, 0), (0, 0), *args, **kwargs) self._verts3d = xs, ys, zs def draw(self, renderer): xs3d, ys3d, zs3d = self._verts3d xs, ys, zs = proj3d.proj_transform(xs3d, ys3d, zs3d, renderer.M) self.set_positions((xs[0], ys[0]), (xs[1], ys[1])) FancyArrowPatch.draw(self, renderer)a = Arrow3D([0, 1], [0, 1], [0, 1], mutation_scale=20, lw=1, arrowstyle="-|>", color="k")ax.add_artist(a)plt.show()
