Anisotropic Rectangular Metric for Polygonal Surface Remeshing
We propose a new method for anisotropic polygonal surface remeshing. Our algorithm takes as input a surface triangle mesh. An anisotropic rectangular metric, defined at each triangle facet of the input mesh, is derived from both a user-specified normal-based tolerance error and the requirement to favor rectangleshaped polygons. Our algorithm uses a greedy optimization procedure that adds, delet...
متن کاملPreparation of Control Space for Remeshing of Polygonal Surfaces
The subject of the article concerns the issues of remeshing, transforming a polygonal mesh into a triangular mesh adapted to its surface. From the initial polygonal mesh, the curvature of surface and boundary is retrieved and used to calculate a metric tensor varying in three-dimensional space. In the proposed approach, the curvature is computed using local approximation of surfaces and curves ...
متن کاملA Shrink Wrapping Approach to Remeshing Polygonal Surfaces
Due to their simplicity and flexibility, polygonal meshes are about to become the standard representation for surface geometry in computer graphics applications. Some algorithms in the context of multiresolution representation and modeling can be performed much more efficiently and robustly if the underlying surface tesselations have the special subdivision connectivity. In this paper, we propo...
متن کاملAnisotropic and feature sensitive triangular remeshing using normal lifting
This work describes an automatic method to anisotropically remesh an input bad quality mesh while preserving sharp features. We extend the method of Lévy and Bonneel [17], based on the lifting of the input mesh in a 6D space (position and normal), and the optimization of a restricted Voronoï diagram in that space. The main advantage of this method is that it does not require any parameterizatio...
متن کاملAnisotropic Franklin bases on polygonal domains
R 2 are explored. Mild conditions are imposed on the triangulations which prevent them from deterioration and at the same time allow for a lot of flexibility and, in particular, arbitrarily sharp angles. It is shown that such anisotropic Franklin systems are Schauder bases for C and L1, and unconditional bases for Lp (1 < p < ∞) and the corresponding Hardy spaces H1. It is also proved that the ...
