Is there a way to get X, Y and Z data back from a surface plot (Poly3DCollection), generated by Axes3D.plot_surface(X, Y, Z)?

CodePudding user response：

xdata, ydata, zdata, _ = ax.collections[0]._vec

Change the index to the correct value if you are plotting multiple surfaces. As far as I know, it is not possible to update these values.
