The geometric centroid of a triangle is therefore also its center of mass, meaning that we could imagine all the mass of the plane object concentrated in this single point.

WebSep 25, 2015 · 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 …
Web2. If a physical object has uniform density, then its center of mass is the same as the centroid of its shape. The requirement for the formula described above is 'a non-self-intersecting closed polygon', so the vertexes of the polygon will form only one non-self … 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.
WebMay 31, 2016 · 2.1 The center of mass of a triangle is the middle of the 3 vertices divided by 3. 2.2 Any other quadrilateral will have 4, 2 or 0 right angle, if it's 4 then we can do the sum of the vertices divided by 4, and if it's 2 or 0 we can calculate the center of mass by splitting the shape again. Let's take a random slab for example. WebCompute the centroid of each triangle (by summing the coordinates of the three corners and dividing by 3). Form a weighted sum of (triangle area) × (triangle centroid). Finally, divide by the total area of the polygon. C code for this computation (which works for nonconvex polygons as well) can be obtained at this link.
