The Marching squares algorithm

Hi all

I have a question about the marching squares algorithm to construct contours based on values in a 2D grid.

I tried to implement this algorithm in LabVIEW but I failed again as I still can't wrap my head around the algorithm.

My question was if it is previously 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've read on the Marching Squares algorithm wikipedia page (http://en.wikipedia.org/wiki/Marching_squares)

Thank you

Lucien

What about the contour line.vi ?
