Constrained Fairing for Meshes
In this paper, we present a novel fairing algorithm for the removal of noise from uniform triangular meshes without shrinkage and serious distortion. The key feature of this algorithm is to keep all triangle centers invariant at each smoothing step by including some constraints in the energy minimization functional. The constrained functional is then minimized efficiently using an iterative met...
متن کاملDiscrete Smooth Interpolation: Constrained Discrete Fairing for Arbitrary Meshes
In this paper, it is shown how the Discrete Smooth Interpolation method (D.S.I.) may be used as a new framework for creating, fairing and editing triangulated surfaces. Given an arbitrary mesh with an arbitrary set of vertices fixed by the user, D.S.I. assigns coordinates to the other nodes of the mesh, enabling the fixed vertices to be interpolated smoothly. The squared discrete Laplacian crit...
متن کاملConstraint-based fairing of surface meshes
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...
متن کاملGeometric fairing of irregular meshes for free-form surface design
In this paper we present a new algorithm for smoothing arbitrary triangle meshes while satisfying boundary conditions. The algorithm is based on solving a non-linear fourth order partial differential equation (PDE) that only depends on intrinsic surface properties instead of being derived from a particular surface parameterization. This continuous PDE has a (representation-independent) welldefi...
متن کاملFairing of Polygon Meshes Via Bayesian Discriminant Analysis
Design of an anisotropic diffusion-based filter that performs Bayesian classification for automatic selection of a proper weight for fairing polygon meshes is proposed. The data analysis based on Bayesian classification is adopted to determine the decision boundary for separating potential edge and non-edge vertices in the curvature space. The adaptive diffusion filter is governed by a double-d...
