XYZ array to intensisty map

[M_Ricci]

In TrianglestoSTL_2.vi there is a button to switch between the two Delaunay triangulations:

native Labview:

and the link:

The last one is faster, but the final result is the same.

In this case they seems not able to create a good 3D triangulation. it's more complex than I thought.

Original points are sorted by z coordinates, while both Delaunay triangulations operate a sort of points in order of ascending xy coordinates.

Could it be a cause of points confusion?
