How to plot and join all random walk points in scatter points

I am trying to generate a sphere based on 3D walk plot and was almost successful. Now i need to generate the random walk points on the sphere to simulate the lighting effects later on but as of now, i cannot see the points getting joined. It simply displays as a dot in the window but doesn’t plot over the sphere. How to overlap the random points on sphere and make them connected? Is it possible to overlap two plots one over the other so that I can present my random walk points on any other 3D plots? Looking forward for your reply.
