Hello,
It seems to me that you just want to plot the curves z=f[x,y] for
fixed values of x. So you could either do something like
Plot[{f[0,y], f[0.5, y], f[1, y]}, {y, 0, 1}]
to get the projections in the y-z-plane, or something like
p1 = Plot3D[f[x, y], {x, 0, 1}, {y, 0, 4\[Pi]}]
p2 = ParametricPlot3D[{{0.2, y, f[0.2, y]}, {0.5, y, f[0.5, y]}, {0.8, y,
f[0.8, y]}}, {y, 0, 4\[Pi]}]
Show[p1,p2]
to obtain the surface z=f[x,y] and the curves at fixed values drawn on
it. It could be necessary to shift the curves a little bit so that
they don't vanish beneath the surface.
Good luck
