I have a set of 3D points that form a polygon. The points are coplanar, due to the fact they are obtained by means of a Voronoi tessellation. I need to compute the area of such polygon. Computing the convex hull is not an option, since the points are coplanar. I thought about computing the centroid and calculating angles but I am struggling to make it work. MWE:
A = [263 274 14.1; 271 276 14.1; 251 296 14.1; 271 300 14.1];
C = mean(A);
and I need the triangulated convex hull or the ID of the points ordered counterclockwise. In this case the answer I need is:
in order to construct a triangulated polygon, of which the calculation of the area is trivial.
