Splet27. nov. 2012 · The alpha shape is proposed by Edelsbrunner and Mucke for computing the 3D structure of a finite point set in space based on the Delaunay triangulation. It is first applied to the field of structural biology by Liang et al. [ 13, 14] to compute the molecular area and volume and detect inaccessible cavities in proteins. http://www.open3d.org/docs/latest/tutorial/Advanced/surface_reconstruction.html disney world wallpaper iphone
