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.

Geometric Centroid -- from Wolfram MathWorld
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). The average y value is y=1/2, but the center of mass is at y=7/12. – WebApr 9, 2024 · That mass of pure story is crucial to the gaming experience, in that it allows the player to decompress after straining to the point of an aneurysm through the brutal duels and cross-examinations ... iift correction window 2022
