[pstricks] Trouble with \psSurface and direction of the hue

[David Tarazona]

efectively that works, i tried:

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

\psset{viewpoint=160 160 120,Decran=200}
\begin{pspicture}(-5,-3)(5,5)
 \psSurface[ngrid=72 72,linewidth=0.01pt,algebraic,tablez=0.8 .1 4 {}
for,zcolor=0.666
0](-3.1416,-3.1416)(3.1416,3.1416){(3-2*cos(x+y)-2*cos(x)+2*cos(y))^(1/2)}
\end{pspicture}

\end{document}

and looks almost orthogonal

ty for the tip and the supoort again...
