On Optimal Tolerancing in Computer-Aided Design
A geometric approach to the computation of precise or well approximated tolerance zones for CAD constructions is given. We continue a previous study of linear constructions and fr...

Polyhedral Surface Smoothing with Simultaneous Mesh Regularization
A computer graphics object reconstructed from real-world data often contains undesirable noise and small-scale oscillations. An important problem is how to remove the noise and os...

Non-Manifold Implicit Surfaces Based on Discontinuous Implicitization and Polygonization
Implicit surfaces in 3D geometric modeling are limited to two manifolds because the corresponding implicit fields are usually defined by real-valued functions which bisect space...

Mesh Smoothing via Mean and Median Filtering Applied to Face Normals
In this paper, we introduce iterative mean and median filtering schemes for smoothing noisy 3D shapes given as triangle meshes. Our main idea consists of applying mean and median...
