Dear all
I want to plot several surfaces in one plot and used for that
ParametricPlot3D. Everything works fine if I enter the definitions for the
functions inline. If I define however a variable (list) that holds the
different functions it does not work anymore. Does anybody know a way out?
The functions I want to plot are for example two spherse of unit radia
centered at 000 and 100. (I need in the end to plot funcitons (R[t,f]
centered at different orrigens)
If I write it inline it works fine
ParametricPlot3D[{{Cos[f] Sin[t], Sin[t] Sin[f], Cos[t]}, {Cos[f] Sin[t] +
1, Sin[t] Sin[f], Cos[t]}}, {t, 0, 3.1415}, {f, 0, 2 3.1415}];
If however I first define my functions and then try to plot:
ToPlot = {{Cos[f] Sin[t], Sin[t] Sin[f], Cos[t]}, {Cos[f] Sin[t] + 1, Sin[t]
Sin[f], Cos[t]}};
ParametricPlot3D[ToPlot, {t, 0, 3.1415}, {f, 0, 2 3.1415}];
I get the error:
ParametricPlot3D::ppfun : Argument ToPlot is not a list with three or four
elements. More.
Since the function I need to plot is a result of a calculation I rather need
to input it as a variable. Any sugestions?
Thanks,
Maurits
