Optimization of Prosthodontic Computer-Aided Designed Models: A Virtual Evaluation of Mesh Quality Reduction Using Open Source Software.

Journal of Prosthodontics, 2020
PURPOSE Mesh optimization reduces the texture quality of three-dimensional models in order to reduce storage file size and computational load on a personal computer. The current study aims to explore mesh optimization using open source (free) software in

Variable mesh optimization for continuous optimization problems

Soft Computing, 2011
Population-based meta-heuristics are algorithms that can obtain very good results for complex continuous optimization problems in a reduced amount of time. These search algorithms use a population of solutions to maintain an acceptable diversity level during the process, thus their correct distribution is crucial for the search. This paper introduces a

Optimal simulation of multidimensional reconfigurable meshes by two-dimensional reconfigurable meshes

Information Processing Letters, 1993
A \(d\)-dimensional reconfigurable mesh (denoted by \(RM^ d)\) consists of processors arranged as a \(d\)-dimensional mesh, in which each processor is connected to its neighbors via input/output ports. Each processor may also internally partition its ports so as to short-circuit all ports in each block of the partition. This partition may change during

Optimization of a triangular mesh

Computers & Structures, 1991
Abstract This paper describes a scheme for finite element mesh generation of a multiply connected, non-convex polygon. The scheme combines a non-random node generation technique and the Delaunay triangulation method for element generation to yield a mesh with optimal shaped elements.

Mesh Optimization for Polygonized Isosurfaces

Computer Graphics Forum, 2001
In this paper, we propose a method for improvement of isosurface polygonizations. Given an initial polygonization of an isosurface, we introduce a mesh evolution process initialized by the polygonization. The evolving mesh converges quickly to its limit mesh which provides with a high quality approximation of the isosurface even if the isosurface has ...

Anisotropic mesh adaption by metric‐driven optimization

International Journal for Numerical Methods in Engineering, 2004
AbstractWe describe a Gauss–Seidel algorithm for optimizing a three‐dimensional unstructured grid so as to conform to a given metric. The objective function for the optimization process is based on the maximum value of an elemental residual measuring the distance of any simplex in the grid to the local target metric.
