David, Thanks for your detailed responses. I didn't get the first plot to work properly. Before I go through the rest of your suggestions, I wanted to understand what I was doing wrong.--Jay "David Park" <djmp at earthlink.net> wrote in message news:bbt1pv$nh8$1 at smc.vnet.net... > Jay, > <snip> > > Here is a set of sample data points. > > points = Table[{x = Random[Real, {-2, 2}], > y = Random[Real, {-2, 2}], > Sqrt[Max[Random[Real, {3, 4}] - x^2 - y^2, 0]]}, > {200}]; > Clear[x, y] > > Needs["Graphics`Colors`"] > > plot1 = > Show[ > Graphics3D[{Red, AbsolutePointSize[4], Point /@ points}] > ]; It only printed the 3D "shell" with no data. I encountered the following error. Graphics3D::"gprim": "\!\(Red\) was encountered where a \!\(Graphics3D\) \ primitive or directive was expected." Do I need to input something else? Thanks, Jay
