Folks,
I am for the most part new to Math 2.0. Here is what I would
like to do:
I would like to plot the surface current on a sphere using
the Mie series solution. I can obtain the current as a scalar
function of (r, theta, phi). I would like to plot this "amplitude"
as a function of (1,theta,phi), ie. I want a 3-D sphere with little
peaks and valleys, sharp points etc. all plotted on a unit sphere.
I hope to be able to animate this sphere so I can show different
viewpoints of the currents.
I have looked at Para..Plot3D[] and SphericalPlot in the Progr..Exam
directory. While I can plot a sphere quite easily I am confused
about plotting a scalar function over a sphere. For my function
would I use something like
Param..3D[ { MieAmplitude[t,u], Sin[t] Cos[u], Sin[u]}, {t,0,2Pi},{u,-Pi/2,Pi/2}]
This doesn't seem to work for me, but I expect it is because I am doing it
wrong.
Now for the big quesition: Has somebody already done this and if so, can
you send me the .m file?
