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

[David Tarazona]

Yes, exactly that's what i'm looking for. Thank you so much... oh yes, for
the information of the mailing list, the next image represents the change
that results from adding
"tablez=0.8 0.01 4 {} for,  zcolor=.666 0" or "zcolor=any hue" to the
options for \psSurface:

Oh yes, I just remembered, how I can see the solids not in perspective but
in orthogonal projection???

I appreciate again if you know how to do it...

thanks again for the support
