"Splet19. avg. 2014 · The Marching Squares algorithm generates an approximation for a contour line of a two dimensional scalar field. Put in another way, if we have a 2D function, this will find an approximation of a line where all points on the line have the same function value. In our case, we’re trying to find the outlines where f ( x, y) = 1 " - The marching squares algorithm
