Hi,
for 3d plot your should look at the
Graphics`ParametricPlot3D` package
There is an CylindricalPlot3D[] function.
you can't.
For DensityPlot[] and ContourPlot[], you can't.
But you can try
DensityPlot[f[Sqrt[x^2+y^2],ArcTan[x,y]],{x,-1,1},{y,-1,1}]
or
f[r_, th_] := r^2*Cos[2*th]
plt = ContourPlot[f[r, th], {r, 0, 1}, {th, 0, 2Pi}];
cp = DeleteCases[Graphics[plt], _Polygon, Infinity] /.
Line[pnts_] :> Line[#[[1]]*{Cos[#[[2]]], Sin[#[[2]]]} & /@ pnts];
Show[cp]
Regards
Jens
