WebYou do this recursively until all your 'holes' shapes are decomposed into convex hulls themselves: meaning you can then handle any geometric task fairly easily. This is the usual (and easiest) way to deal with concave shapes. Building up your shape as a set of convex hulls is harder: using triangles is the probably the best way for this. WebAlpha shape. Convex hull, alpha shape and minimal spanning tree of a bivariate data set. In computational geometry, an alpha shape, or α-shape, is a family of piecewise linear simple curves in the Euclidean plane associated with the shape of a finite set of points. They were first defined by Edelsbrunner, Kirkpatrick & Seidel (1983).
