Dear Luca,

perhaps you might try with Tom Wickham-Jones' Graphics Extensions
(http://www.mathsource.com/Content/Enhancements/Graphics/3D/0208-976)

and then use

<< ExtendGraphics`SurfaceGraphics3D`

data = Table[{x = Pi Random[], y = 2 Pi Random[], Sin[x] Sin[y]},
{100}];

ListSurfacePlot3D[data, BoxRatios -> {1, 1, 0.8}, ViewPoint -> {1.6,
-0.3, 2}]
