The nonconforming virtual element method for eigenvalue problems
, 2018 We analyse the nonconforming Virtual Element Method (VEM) for the approximation of elliptic eigenvalue problems. The nonconforming VEM allow to treat in the same formulation the two- and three-dimensional case.We present two possible formulations of the ...

Evo-Devo Strategies for Generative Architecture: Colour-Based Patterns in Polygon Meshes
Biomimetics, 2020 Parametric design in architecture is often pigeonholed by its own definition and computational complexity. This article explores the generative capacity to integrate patterns and flows analogous to evolutionary developmental biology (Evo-Devo) strategies

HIERARCHICAL REGULARIZATION OF POLYGONS FOR PHOTOGRAMMETRIC POINT CLOUDS OF OBLIQUE IMAGES [PDF]
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2017 Despite the success of multi-view stereo (MVS) reconstruction from massive oblique images in city scale, only point clouds and triangulated meshes are available from existing MVS pipelines, which are topologically defect laden, free of semantical ...

Embedded Implicit Stand-ins for Animated Meshes: a Case of Hybrid Modelling [PDF]
, 2008 In this paper we address shape modelling problems, encountered in computer animation and computer games development that are difficult to solve just using polygonal meshes.

Discontinuous Galerkin Methods for the Biharmonic Problem on Polygonal and Polyhedral Meshes [PDF]
, 2018 We introduce an $hp$-version symmetric interior penalty discontinuous Galerkin finite element method (DGFEM) for the numerical approximation of the biharmonic equation on general computational meshes consisting of polygonal/polyhedral (polytopic ...

Hybridized CutFEM for Elliptic Interface Problems [PDF]
, 2018 We design and analyze a hybridized cut finite element method for elliptic interface problems. In this method very general meshes can be coupled over internal unfitted interfaces, through a skeletal variable, using a Nitsche type approach.

Constrained texture mapping for polygonal meshes [PDF]
Proceedings of the 28th annual conference on Computer graphics and interactive techniques, 2001 Recently, time and effort have been devoted to automatic texture mapping. It is possible to study the parameterization function and to describe the texture mapping process in terms of a functional optimization problem. Several methods of this type have been proposed to minimize deformations.
