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 Martin Kraus
