Hi,

myPlot3D[fun_, {x_, x1_, x2_}, {y_, y1_, y2_}, opts___] :=
  Block[{ff},
    ff[xx_, yy_] = 
      If[xx < x1 || xx > x2 || yy < y1 || yy > y2, 0, 
        fun /. {x -> xx, y -> yy}];
    Plot3D[
      Evaluate[ff[xx, yy]], {xx, x1 - 0.01, x2 + 0.01}, {yy, y1 - 0.01, 
        y2 + 0.01}, opts]
    ]

myPlot3D[Cos[Sqrt[x^2 + y^2]] + 1, {x, -Pi/2, Pi/2}, {y, -Pi/2, Pi/2}, 
  PlotPoints -> 30]

??


Regards
  Jens
