Even though your data represents a 3D geometrical surface, if the data in
"filename" is in the form,

x1  y1  f1
x2  y2  f2
...
...


then Import["filename.ext","Table"] will give you a 2D list of the form. of
the form { {x1,y1,f1}, {x2,y2 ,f2}, ...} which is exactly what you need for
ListSurfacePlot3D  located in the package Graphics'Graphics3D.
