Re: Shading in Plot3D

Without shading it is very difficult to visualize

Column[Plot3D[Sin[x y],
    {x, -Pi, Pi}, {y, -Pi, Pi},
    PlotPoints -> Automatic,
    Mesh -> {{-Pi/2, 0, Pi/2},
      {-Pi/2, 0, Pi/2}},
    MeshStyle -> {
      {Black, Thickness[0.004]}},
    PlotRange -> All,
    BaseStyle -> {12, Bold},
    Boxed -> False,
    ImageSize -> 300,
    #] & /@
  {ColorFunction -> White,
   Lighting -> {{"Ambient", White}}}]

=============
All,

I want to use Plot3D to produce a surface with no shading. All I want is a black-and-white plot: black meshlines and a white surface.

But no matter what I try, I get gray shading. I've done my due diligence in the Documentation Center, but can't find the key to turn off all shading.

Can anyone help?

Here's the Plot3D command I'm using, which gives me a white surface with the black meshlines, but with the unwanted shading.

Plot3D[Sin[x y], {x, -Pi, Pi}, {y, -Pi, Pi}, PlotPoints -> Automatic, 
 Mesh -> {{-Pi/2, 0, Pi/2}, {-Pi/2, 0, Pi/2}}, 
 MeshStyle -> {{Black, Thickness[0.004]}, {Black, Thickness[0.004]}}, 
 PlotRange -> {All, All, All}, BaseStyle -> {FontSize -> 12, Bold}, 
 Boxed -> False, PlotRegion -> {{0.025, 0.975}, {0.025, 0.975}}, 
 MeshShading -> None, Exclusions -> None, ColorFunction -> {White}]


Thanks in advance.
