x[a_, b_] = a*b;
y[a_, b_] = Cos[a^2 + b];
z[a_, b_] = Sin[a + b^2];
data = Table[
{x[i, j], y[i, j], z[i, j]},
{j, -1, 1, 0.1}, {i, -2, 2, 0.1}] //
Flatten[#, 1] &;
ListContourPlot[data]
ListContourPlot3D[data]
However, both ListContourPlot and ListContourPlot3D are difficult to
interpret for this complicated function. I recommend that you look at
the function with ParametricPlot3D.
Manipulate[
ParametricPlot3D[
Evaluate[
{x[a, b], y[a, b], z[a, b]}],
{a, -2, 2}, {b, -1, 1},
RegionFunction -> (#3 <= slice &),
BoundaryStyle ->
Directive[Black, Thick],
PlotRange ->
{{-2, 2}, {-1, 1}, {-1, 1}},
PlotPoints -> 50],
{{slice, 1}, -0.95, 1, 0.05,
Appearance -> "Labeled"}]
