I have a data file with a set of points (x,y,z) that are restricted to the surface of a sphere. I would like to plot them, but I wouldn't like all the points to appear on the plot, only the ones visible in 3d. My idea is to draw a solid sphere in order to hide the points from the back. I tried following this answer, but first, if I plot in pdf I get this.
Second, I would like to plot the points as dots with pt7 or something small, but in the gnuplot qt viewer there is still a white wireframe, as seen:
I would like to achieve something similar to this:
How can I remove this wireframe? If someone knows a simpler way to do this with pgfplots, tikz or other software it would also suffice me.
