The Marching Squares Algorithm

Solved!
Go to solution

Hello all,

 

I have a question regarding the marching squares algorithm in order to construct isolines based on values in a 2D grid.

I tried to implement this algorithm in LabVIEW, but I haven't succeeded yet as I still can't wrap my head around the algorithm.

 

My question was if there is pre-written code of the marching squares algorithm? I also have my attempt to implement the algorithm VI  attached if that's any help.

My attempt is based on the information I have read on the wikipedia page Marching Squares Algorithm (http://en.wikipedia.org/wiki/Marching_squares)

 

Thanks,

 

Lucien

What are you intending to do with the isoline data - draw a picture?

My intention is to draw an isoline of a magnetic field. Like this: http://2.bp.blogspot.com/_7VQT2zZL1g0/SpeE4451VbI/AAAAAAAAAFU/xESt6Uurh3k/s1600-h/fringe+Field+Side+...

I have measured the magnetic field of a transformer on 25 points in a 2,5 m x 2,5 m grid and am trying to calculate an magnetic field isoline based on my measured 25 points.
