The source function in this case was defined by a scattered data set resulting from a laser scan of a Ski-Doo hood
(whatever that is). This data set consists of 37,594 sample points. To interprete this data set as a function, we
projected all points on a best square fitting plane, took their plane parameters as the (x, y)
parameter values and the distance from the plane as the z value.
The left column shows the linear spline itself, the right column shows the spline's connectivity as a triangle mesh.
