A locally conservative staggered least squares method on polygonal meshes
Mathematics in EngineeringIn this paper, we propose a novel staggered least squares method for elliptic equations on polygonal meshes. Our new method can be flexibly applied to rough grids and allows hanging nodes, which is of particular interest in practical applications ...

Survey of polygonal surface simplification algorithms on GPU
Труды Института системного программирования РАН, 2018 Rendering time depends on number of faces in polygonal mesh. Displaying large number of objects or objects with a lot of faces can result in performance degradation.

Boolean operations between two colliding shells: a robust, exact, and simple method
Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2017 Boolean operations are classic procedures in computer-aided design, and allow the creation of complex objects by combining simple objects. Although Boolean operations are trivial in implicit surface representations, they are problematic in polygonal ...

A TWELVE NODED FINITE ELEMENT APPROXIMATION TO 2D-POISSON EQUATIONS WITH A DIRAC LINE SOURCE [PDF]
Journal of Mechanics of Continua and Mathematical SciencesThis paper presents the finite element approach to solving the Poisson equation. Using Dirichlet boundary conditions in a two-dimensional polygonal region, the polygon to be discretized is made up of twelve-noded quadrilateral structured meshes.

A comparison of hole-filling methods in 3D
International Journal of Applied Mathematics and Computer Science, 2016 This paper presents a review of the most relevant current techniques that deal with hole-filling in 3D models. Contrary to earlier reports, which approach mesh repairing in a sparse and global manner, the objective of this review is twofold.
