Re: Sub-division of surface plotting by PlotPoints->{m,n}

Use a combination of PlotPoints and MaxRecursion to control the subdivision 
of the surface.
Use Mesh -> All to see what Mathematica is actually doing.

ParametricPlot3D[{u Cos[t], u Sin[t], t}, {u, 1, 2}, {t, 0, Pi},
 PlotPoints -> {2, 3},
 MaxRecursion -> 4,
 Mesh -> All]
