Marching square vs delaunay
WebJun 14, 2024 · I can say that a Delaunay triangulation achieves the best triangle-area/triangle-perimeter ratio (best theorethical ratio is with equilateral triangles). But you … In computer graphics, marching squares is an algorithm that generates contours for a two-dimensional scalar field (rectangular array of individual numerical values). A similar method can be used to contour 2D triangle meshes. The contours can be of two kinds: • Isolines – lines following a single data level, or isovalue.
