"To get a polygon out of a scalar field (e.g. a bitmap) you should first run a modified version of marching squares that only generates the polygon contour (i.e. in the 16 cases of marching squares you don't generate geometry, you just add points to a polygon), and after that you run a triangulation algorithm (e.g. Delaunay or Ear Clipping)."
