You have to slightly modify your conditions, so as not to leave holes in the range of definition. Try
In[1]:=
f[x_, y_] := x^2 + y^2 /;
x^2 + y^2 < 1;
f[x_, y_] := 2 /; x^2 + y^2 >= 1;
In[2]:=
Plot3D[f[x, y], {x, -3, 3},
{y, -3, 3}, PlotPoints ->
100];

Hi,
Could somebody tell me how to plot the graph of bump functions. For
example, if I want to draw the graph of the function say,
f(x,y) = x^2+y^2 for x^2+y^2<1
= 2 for x^2+y^2 >2
Thanks
