I'm sure there must be an easier way to do this, but the way I've done this in the past is to create a 2D density plot of the function using DensityPlot[] and use that plot as the texture of a rectangle in the 3D plot. So to mimic the example in the link, you would get something like
f[x_, y_] := 1 - Cos[10 Sqrt[x^2 + y^2]]/Exp[10 (x^2 + y^2)]
zmin = -1;
densPlot =
DensityPlot[f[x, y], {x, -1, 1}, {y, -1, 1},
PlotRange -> {{-1, 1}, {-1, 1}, {0, 2}}, Frame -> False,
ColorFunction -> (ColorData[{"DeepSeaColors", "Reverse"}][#] &)];
projection =
Plot3D[zmin, {x, -1, 1}, {y, -1, 1}, PlotStyle -> Texture[densPlot],
Mesh -> False];
plot = Plot3D[f[x, y], {x, -1, 1}, {y, -1, 1},
BoxRatios -> {1, 1, 0.8},
PlotRange -> {Automatic, Automatic, {zmin, 2}}, PlotPoints -> 30,
PerformanceGoal -> "Quality", PlotStyle -> Opacity[0.1],
MeshStyle -> Directive[Darker[Gray], Dashed],
Mesh -> {30, 30},
ColorFunction -> (ColorData[{"DeepSeaColors", "Reverse"}][#3] &),
Lighting -> "Neutral"];
Show[plot, projection]
