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]; Tomas Garza Mexico City Original Message: ----------------- From: Ajitkumar ajitkumar at math.mu.ac.in To: mathgroup at smc.vnet.net Subject: [mg31978] [mg31967] Bump Function 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 Ajit Kumar Dept of Maths University of Mumbai Vidyanagari, Kalina Mumbai 400 098 India Phone No. +91 652 6683 Email- ajitkumar at math.mu.ac.in ajit_kumara at hotmail.com http://math.mu.ac.in/faculty/scholars/ajit.html -------------------------------------------------------------------- mail2web - Check your email from the web at http://mail2web.com/ .
