Hello,

just an idea: Rotate the points 90 degrees about the 
y axis (Rotate3D from the Geometry`Rotations` 
package). Then use TriangularSurfacePlot from the 
DiscreteMath`ComputationalGeometry` package to 
build the surface. Finally rotate back 
(RotateShape from the Graphics`Shapes` package).

Hope this helps
