Point in Polygon for LabVIEW 2015

[EngrStudent]

I found this:

http://zone.ni.com/reference/en-XX/help/371361H-01/gmath/point_in_polygon/

It looks great, but the help is for LabVIEW 2011/2012.  Where do I find it for LabVIEW 2015?

Thanks.

Look on the Mathematics sub-Palette, where you should find a Geometry folder with a Computational Geometry sub-Folder.

Note that when you know the name of the subVI like you do in this case, there is a Search button in the upper right corner of the palette that will find the subVI for you.

I tried searching first and it didn't work, but I may have been using the wrong name.

Then I asked the question.

Then I went google-searching.  There was a gmath library.

I used VIPM and found a gmath library, then installed it, then I was able to find the computational geometry with the "in polygon" function.

Hi Engr,

when you know the name of a VI (atleast partly) you could always open Quickdrop by Ctrl-Space and type parts of the name.

Typing "polygon" in QuickDrop easily finds the "Point in polygon" function!

Also the LabVIEW help always names the "owning palette" - for this function it didn't change from LV2012 to LV2017!

I don't know why you need to install a 3rd party VI library for that function…

GerdW,

I was thinking the install might have had nothing to do with the solution.  I figured that I was confused.

I don't know why you'd need to go to VI package manager.  And anything there is probably different than the one in the link you provided.

The one in the link is built into LabVIEW.  Or at least if you have Full Development version or higher.  Is it any chance you are only using the Basic version of LabVIEW?
