Hull convex
WebA nice consequence of implementing 3D convex hull is that we get Delaunay triangulation for free. We can simply map each point ( x, y) into a 3D point ( x, y, x 2 + y 2). Then the downward-facing triangles of the 3D convex hull are precisely the Delaunay triangles. The proof is left as an exercise to the reader. WebThe convex hull can be used to check whether a certain composition is stable or it will decompose into mixed phases of the neighboring stable compositions. We will use a …
