For each real number α, define the concept of a generalized disk of radius 1/α as follows: If α = 0, it is a closed half-plane;If α > 0, it is a closed disk of radius 1/α;If α < 0, it is the closure of the complement of a disk of radius −1/α. Then an edge of the alpha-shape is drawn between two members of the finite point set … Visa mer 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, … Visa mer This technique can be employed to reconstruct a Fermi surface from the electronic Bloch spectral function evaluated at the Visa mer • 2D Alpha Shapes and 3D Alpha Shapes in CGAL the Computational Geometry Algorithms Library • Alpha Complex in the GUDHI library. Visa mer Alpha shapes are closely related to alpha complexes, subcomplexes of the Delaunay triangulation of the point set. Each edge or triangle … Visa mer • Beta skeleton Visa mer
