Remeshing controlled by barrier crossings in a double-barrier potential.
(A) Remeshing via flipping procedures. (B) Remeshing via splitting and merging procedures controlled by barrier crossings in a potential Vin at indicated lengths. (C) Initial triangular meshes and high-quality triangular mesh after relaxation. (D) Triangular mesh element: right-hand rule. (E) Definition of 1-ring neighbors nb(i) and Voronoi area Av in purple [30]. ri and rj are the vectors defined by vertex i and j, and θij and ϕij are the two angles for computing the discrete Helfrich energy at i Eq (5).
