Domain Decomposition for Mean Curvature Flow of Surface Polygonal Meshes
Lenka Ptackova, Michal Outrata
We examine the use of domain decomposition for potentially more efficient mean curvature flow of surface meshes, whose faces are arbitrary simple polygons. We first test traditiona…
A discrete wedge product on general polygonal meshes
Lenka Ptackova
Discrete exterior calculus offers a coordinate--free discretization of exterior calculus especially suited for computations on meshes over curved manifolds. The discretization of t…
A simple and complete discrete exterior calculus on general polygonal meshes
Lenka Ptackova, Luiz Velho
Discrete exterior calculus (DEC) offers a coordinate-free discretization of exterior calculus especially suited for computations on curved spaces. In this work, we present an exten…
Bézier curves and the Takagi function
Lenka Ptackova, Franco Vivaldi
We consider Bézier curves with complex parameters, and we determine explicitly the affine iterated function system (IFS) corresponding to the de Casteljau subdivision algorithm, to…
