Mesh refinement with color attributes

Computers & Graphics, 2001
Abstract Although many sophisticated solutions have been proposed to reduce the geometry complexity of a 3D mesh, few of these take into account color and texture fields, which are fundamental for a visual appearance of high quality. We propose here an innovative solution which combines the concept of hierarchy in refining a mesh with color ...

Polyhedra operators for mesh refinement

Geometric Modeling and Processing. Theory and Applications. GMP 2002. Proceedings, 2003
We study the factorization of mesh refinement rules in terms of the polyhedra operator's duality, stellation, and truncation. Using this factorization, we show that the /spl radic/3-refinement and leapfrog transformation, known from its applications in discrete mathematical chemistry, differ by a conjugation by the duality operator.

Refinement strategies in adaptive meshing

IEEE Transactions on Magnetics, 1992
Two strategies for reducing the overall number of finite-element computations needed in an adaptive meshing algorithm are proposed. In the first strategy (called two-threshold refinement), numerical values of the estimated local error are used both to select the elements to be refined and to decide into how may new elements each of them will be ...

Multigrid for Locally Refined Meshes

SIAM Journal on Scientific Computing, 1999
A multilevel method for the solution of finite element methods on locally refined meshes is introduced. An upper bound for the condition number is given in the two-level semi-positive definite case under the additional assumption that the coefficient matrix is diagonally dominant.

Domain Decomposition with Local Mesh Refinement

SIAM Journal on Scientific and Statistical Computing, 1992
The authors present a preconditioned Krylov iterative algorithm which can be used to solve systems of linear equations arising from the discretization of partial differential equations. The main feature of their method lies in the combined admissibility of domain decomposition and local mesh refinements. By way of illustration, the method is applied to
