XYZ array to intensisty map

[altenbach]

Here's how to use the original points to create the STL file. Seems trivially simple.

(and please don't use a greedy loop to waste 100% of a CPU core doing nothing until stop is pressed, see also)

Great Altenbach!
It works very well, thank you!

The last point: the process creates a closed surface (see image A), probably because in the last loops it creates triangulations (see image B and zoom B2).
Is it possible to try avoiding triangulation on this side, in order to open the surface?

[altenbach]

You can filter out any triangles that you don't want, of course. (In this case, you could filter any triangles where all three vertices have the same specific Z value.)

You posted in a pretty old version (2013). What is your actual LabVIEW version?

[altenbach · Accepted solution]

Assuming your LabVIEW version has the conditional output tunnel, here's all you need to do. Try it!

(slightly simpler logic is possible, but harder to read)

[M_Ricci]

Perfect, thank you Altenbach for your huge support!

One alternative (checking it at least one is different)...

On a side note, this entire method only works for a planar arrangement in x and y, i.e. if there are no multiple planes (e.g. a sphere or a donut, etc.). A more general solutions for points in 3D would involve more code (see here).
