Center of mass of a polygon

WebAug 19, 2013 · Commonly used "centers" that are simple to compute are the average of all vertices, the average of the boundary, the center of mass or even just the center of the axis-aligned bounding box. All of them can however fall outside the polygon if the polygon is not convex, but in your case they may work.

WebAug 17, 2016 · The centroid (a.k.a. the center of mass, or center of gravity) of a polygon can be computed as the weighted sum of the centroids of a partition of the polygon into triangles. The centroid of a triangle is simply the average of its three vertices, i.e., it has coordinates (x1 + x2 + x3)/3 and (y1 + y2 + y3)/3. This suggests first triangulating ... WebJan 11, 2016 · This method works for triangles. It does not work for polygons with 4 or more vertices. A simple counter-example is a polygon with vertices (1,0), (2,0), (3,1), (0,1).
