RevolutionPlot3D[c4*z4[rho, theta],
{rho, 0, 1}, {theta, 0, 2*Pi},
ColorFunction -> (ColorData["Rainbow"][1 - #3] &)]

Hi everybody,
I am plotting Zernike-Polynomials like this:
---------
c4 = 1;
z4[rho_, theta_] := rho^2*Cos[2*theta]
RevolutionPlot3D[c4*z4[rho, theta], {rho, 0, 1}, {theta, 0, 2*Pi},
ColorFunction -> "Rainbow"]
---------
To be able to compare the plot to measured data from an
interferometer, I would like to invert the Rainbow colouring, that is
red at the bottom and blue on top. However, I can't find to work this
out. Does anyone know how to do this?
Thank you,
Vladimir.
