You can do it in this way (assuming theta is longitudinal and phi is asimuthal): ParametricPlot3D[f[theta,fi]*{Sin[theta]Cos[phi],Sin[theta]Sin[phi],Cos[phi]}, {theta, 0, Pi}, {phi, 0, 2*Pi}] This will create a point distance f away. Works nice for plotting spherical harmonics, although you might want to adjust the PlotPoints parameter to get nice looking results.
