Constraint-based fairing of surface meshes
نویسندگان
چکیده
We propose a constraint-based method for the fairing of surface meshes. The main feature of our approach is that the resulting smoothed surface remains within a prescribed distance to the input mesh. For example, specifying the maximum distance in the order of the measuring precision of a laser scanner allows noise to be removed while preserving the accuracy of the scan. The approach is modeled as an optimization problem where a fairness measure is minimized subject to constraints that control the spatial deviation of the surface. The problem is efficiently solved by an active set Newton method.

Multiresolution Methods for Nonmanifold Models
The concept of fairing applied to triangular meshes with irregular connectivity has become more and more important. Previous contributions proposed a variety of fairing operators for manifolds and applied them to design multiresolution representations and editing tools for meshes. In this paper, we generalize these powerful techniques to handle non-manifold models. We propose a method to constr...
متن کاملAn Approach for 3d Segmentation on Multiresolution Surfaces
We present an approach for 3D segmentation on multiresolution surfaces of 3D data that are represented in the form of triangular meshes. In this approach, multiresolution surfaces are generated by applying two algorithms, mesh decimation and surface fairing methods. The decimation method simplifies surfaces into less complex forms which contain less details than the original surface. The surfac...

The concept of fairing applied to irregular triangular meshes has become more and more important. Previous contributions constructed better fairing operators, and applied them both to multiresolution editing tools and to multiresolution representations of meshes. In this paper, we generalize these powerful techniques to handle non-manifold models. Our framework computes a multilevel fairing of ...
متن کاملAnisotropic Di usion of Noisy Surfaces and Noisy Functions on Surfaces
We present a uni ed anisotropic geometric di usion PDEmodel for smoothing (fairing) out noise both in triangulated 2-manifold surface meshes in IR and functions de ned on these surface meshes, while enhancing curve features on both by careful choice of an anisotropic di usion tensor. We combine the C limit representation of Loop's subdivision for triangular surface meshes and vector functions o...
متن کاملAdaptive Fairing of Surface Meshes by Geometric Diffusion
In triangulated surface meshes, there are often very noticeable size variances (the vertices are distributed unevenly). The presented noise of such surface meshes is therefore composite of vast frequencies. In this paper, we solve a diffusion partial differential equation numerically for noise removal of arbitrary triangular manifolds using an adaptive time discretization. The proposed approach...
