I draw the discretized surface of a disk using Axes3d.plot_wireframe, and on the same graph I superimpose a point corresponding to the center of the disk using Axes3d.scatter (attached figures). My problem is that the point is only visible when the disc is seen in profile. I would like it to be visible regardless of the view. I am also joining part of my script (sorry if it doesn't appear as it should).

I tried changing the order of the plots in my script, I tried adding a 'zorder' argument in both plots, and I also tried changing the marker size in the scatter plot but it did not work.
