Remeshing flexible membranes under the control of free energy
Fig 4
Applications of the proposed method to generate high-quality meshes of salient geometries under external forces.
(A) Definition of external control points attracting the nearest mesh vertex i and i’s 1-ring neighbors nb(i). (B) Formation of a filopodium by placement of a control point at the tip and control points holding the remainder of the globular cell in place. (C) Formation of a lamellipodium by placement of control points in a circular rim and control points holding the remainder of the globular cell in place. (D) Formation of an invagination by placement of a control point 1/3 into the globular cell and control points holding the remainder of the cell in place. Matching videos are provided in S4–S6 Videos (2 × 104 iterations).
