pst-solides3d provides only perspective projections. But you can set the
viewpoint far away from the object.

\begin {document}

\psset{Decran=50,viewpoint=40 80 10 rtp2xyz}
 \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)%
