You can't use parametric plot because that's a function for 2D graphics. You might use ParametricPlot3D but then you'd have to obtain the parametric equations of the sphere first (no big deal, though). But you may use directly ContourPlot3D: In[1]:= <<Graphics`ContourPlot3D` In[2]:= ContourPlot3D[x^2 + y^2 + z^2 - 1, {x, -2, 2}, {y, -2, 2}, {z, -2, 2}, PlotPoints -> {3, 15}] Tomas Garza Mexico City > -----Original Message----- > From: Daniel Meisel [mailto:Daniel.Meisel at Physik.UNI-Karlsruhe.de] To: mathgroup at smc.vnet.net > Sent: Monday, December 17, 2001 11:34 PM > To: mathgroup at smc.vnet.net > Subject: [mg32026] [mg32006] ImplicitPlot3d > > > Hi, > > I'm searching for a way to plot for example the equation > > x^2 + y^2 + z^2 =1 > > ( a sphere around the origin with radius 1) in 3d. > > I cannot use the parametric plot command. > > thanks in advance > >
