Is it possible to create a revolution plot directly from a parametric function?

For example, I have a 2d parametric function

x[u]=Cos[u]*(1 + 2 Cos[2 u])
y[u]=Sin[u]*(1+2Cos[2 u])

and the function looks like this when plot of u from 0 to pi

how can we rotate it around the x axis and make it into a revolution plot like

Thanks for the help in advance.
