CircularPlot3D Package

CircularPlot3D[f,{r,rmin,rmax}] will produce a 3D plot of the real valued function f. The function f may be given either in the rectangular variables x and y or in the polar variables r and theta. The domain will be a circle centered at the origin (or centered at the point specified by the option Center). A typical setting might for the Center option might be Center->{1,2}. CircularPlot3D will accept a third argument: CircularPlot3D[f,{r,rmin,rmax},{theta,thetamin,thetamax}] will only produce that portion of the plot with polar angle theta in the specified range. CircluarPlot3D will accept any options accepted by ParametricPlot3D. Note:If the function f is given in rectangular coordinates using variables whose names are not x and y, or if the command is used in a context other than Global` one must use the more formal syntax: CircularPlot3D[f,{xvar,yvar},{r, rmin, rmax}], where xvar and yvar indicate the names of the variables appearing in f.
