use pst-solides3d instead. You can color the image
depending to the z value. Have a look into the doc
or search for z coloring.

\documentclass{article}
\usepackage{pst-solides3d}
\begin{document}

\psset{viewpoint=50 40 30 rtp2xyz,Decran=50}
\psset{lightsrc=viewpoint}
\begin{pspicture}(-6,-7)(7,7)
\psSurface[ngrid=.2 .2,Zmin=0,Zmax=3,
  linewidth=0.5\pslinewidth,
  algebraic](-4,-4)(4,4){Euler^(-(x^2+y^2)/2)*3 }
\end{pspicture}

\end{document}
