Aggressive Tetrahedral Mesh Improvement
We present a tetrahedral mesh improvement schedule that usually creates meshes whose worst tetrahedra have a level of quality substantially better than those produced by any previous method for tetrahedral mesh generation or “mesh clean-up.” Our goal is to aggressively optimize the worst tetrahedra, with speed a secondary consideration. Mesh optimization methods often get stuck in bad local opt...
متن کاملThe Adaptive Thin Shell Tetrahedral Mesh
Tetrahedral meshes are often used for simulating deformable objects. Unlike engineering disciplines that often focuses on accuracy, computer graphics is biased towards stable, robust, and fast methods. In that spirit we present an approach for building an adaptive inward shell of the surface of an object. The goal is to device a simple and fast algorithm capable of building a topologically cons...
متن کاملA Comparison of Tetrahedral Mesh Improvement Techniques
Automatic mesh generation and adaptive reenement methods for complex three-dimensional domains have proven to be very successful tools for the eecient solution of complex applications problems. These methods can, however, produce poorly shaped elements that cause the numerical solution to be less accurate and more diicult to compute. Fortunately, the shape of the elements can be improved throug...

Automatic mesh generation and adaptive reenement methods for complex three-dimensional domains have proven to be very successful tools for the eecient solution of complex applications problems. These methods can, however, produce poorly shaped elements that cause the numerical solution to be less accurate and more diicult to compute.

متن کاملTetrahedral Mesh Improvement Using Multi-face Retriangulation
In this paper we propose a simple technique for tetrahedral mesh improvement without inserting Steiner vertices, concentrating mainly on boundary conforming meshes. The algorithm makes local changes to the mesh to remove tetrahedra which are poor according to some quality criterion. While the algorithm is completely general with regard to quality criterion, we target improvement of the dihedral...
