The coordinate mesh used by ParametricPlot3D is equidistant, so
you need to do the refinement by yourself. For example,
X[x_] := x^2;
Y[y_] := y^2;
ParametricPlot3D[{f1(X[x],Y[y]),f2(X[x],Y[y]),f3(X[x],Y[y]),{x,-10,10},{y,-10,10}]
I was hoping that Mathematica 4.0 would implement automatic mesh refinement...
