That is only guaranteed to apply for convex polygons. – Hong Ooi. Mar 22, 2012 at 2:51. Yes the algorithm is correct I agree, but is there another algorithm that will ensure that a point within the polygon is calculated? Ideally the result for the above shape would be (1.5, 1.5).
WebIn geometry, a convex polygon is a polygon that is the boundary of a convex set. This means that the line segment between two points of the polygon is contained in the union … WebThis will work for triangles, regular and irregular polygons, convex or concave polygons.

The centroid occurs somewhere within the range of contact between the two shapes (and exactly at the point where the shape would balance on a pin). See more In mathematics and physics, the centroid, also known as geometric center or center of figure, of a plane figure or solid figure is the arithmetic mean position of all the points in the surface of the figure.
