Hi,



gr = Graphics3D[Plot3D[Sin[x*y], {x, 0, Pi}, {y, 
0, Pi}]]

Show[gr /. Polygon[pnts_] :> Polygon[{{1, 0, 0},
{0, -1, 0}, {0, 0, 1}}.# & /@ pnts]
]

will mirror the y-axes.

Regards

  Jens

| Hi,
|
| I've got this nice Plot3D surface, but 
unfortunately I want one of the
| axes to run from 200 to 1, instead of the 
natural 1 to 200.  I've tried
| {S, 200, 1} instead of {S, 1, 200}, but that 
didn't work.    The
| function is quite involved and I'd rather not 
change it.
|
| Effectively what I want to do is to mirror the 
whole surface in a
| vertical plane.
|
| Can anyone help me and think of a [hopefully 
simple] way to do this?
|
| Many thanks,
| David.
