Here is what I have so far:

\documentclass{amsart}

\usepackage{pst-solides3d}

\begin{document}

\psset{Decran=20,viewpoint=40 20 20 rtp2xyz,lightsrc=viewpoint,action=draw**,
       fillcolor=blue!30!white,linewidth=0.1pt}
\psset{incolor=red!60!white}

\begin{pspicture}(-1.5,-1)(1.5,3)
\psSolid[object=sphere,r=3,ngrid=20 20,hollow](0,0,2)
\end{pspicture}

\end{document}

I would like to remove all the horizontal lines from the grid, and leave only the vertical ones. For example:
