3D Triangulation

Hi,

I have a question about a 3d Triangulation on a Surface.

Here is the scenario: (find attached File).

I have a bunch of unordered non systematic measurement points on a surface and I would like to create a 3d Triangulation on that surface. (Resulting in Splines on the
Surface)

The Surface is a deformed, revolved surface.

Here is what I tried (and did not work)

-          Creating the UV curves (using a trick to position the point). Then use the Delaunay
triangulation and apply the curves again. That worked quite well, accept that
in the area where the two surface edges meet, there is no correct connection.

-         I connected all point with all points with lines and the filtered them by length,
leaving only the ones that are close together. But that way I get too many
intersecting lines. Since it is 3d I cannot filter intersecting lines.

-          Then I tried the first method, with splines on surface (shortest distance) but as
expected the program crashed, while trying to do that.

Does anyone have a solution for this problem? (GH, Script, .Net all works for me)

Thanks in advance for your help.
