From the List of centroids, we note the coordinates of the individual centroid. Midpoints of sides are mapped onto midpoints and centroids on centroids. The point set formula 6 represents the Gaussian mixture model (GMM) centroids. The centroids of the clusters are then taken to represent the fragment. The insphere is tangent to the faces at their face centroids. Let the centroids of these triangles be "X", "Y" and "Z" respectively. The following is a list of centroids of various two-dimensional and three-dimensional objects. Unless stated, positions are the centroids of the two-dimensional shapes made by the countries. The Columbus/Dayton corridor is considered one of two "centroids" in America's logistics sector. Centroids are estimated center points within a zone.
