A distortion measure to validate and generate curved high-order meshes on CAD surfaces with independence of parameterization
(Wiley Online Library, 2015-12-15)
Article
Accés obertA framework to validate and generate curved nodal high-order meshes on Computer-Aided Design (CAD) surfaces is presented. The proposed framework is of major interest to generate meshes suitable for thin-shell and 3D finite ... -
Defining an L2-disparity Measure to Check and Improve the Geometric Accuracy of Non-interpolating Curved High-order Meshes
(Elsevier, 2015)
Article
Accés obertWe define an Full-size image L2-disparity measure between curved high-order meshes and parameterized manifolds in terms of an Full-size image L2 norm. The main application of the proposed definition is to measure and improve ... -
High-order mesh curving by distortion minimization with boundary nodes free to slide on a 3D CAD representation
(Elsevier, 2016-03)
Article
Accés obertWe propose a 3D mesh curving method that converts a straight-sided mesh to an optimal-quality curved high-order mesh that interpolates a CAD boundary representation. The main application of this method is the generation ... -
Interpolation of subdivision features for curved geometry modeling
(2022-04)
Article
Accés obertWe present a nodal interpolation method to approximate a subdivision model. The main application is to model and represent curved geometry without gaps and preserving the required simulation intent. Accordingly, we devise ... -

Octree detection of closed compartments
(ACM Press, NY, 1991)
Text en actes de congrés
Accés restringit per política de l'editorialThe present paper addresses the problem of detecting closed compartments produced by a set of planar faces in the space. The topology of the set is general, and edges in the final piecewise planar surface can belong to ... -
Octree-based view-dependent triangle meshes
(2007)
Text en actes de congrés
Accés restringit per política de l'editorialIn this paper we present a new technique for view-dependent LOD rendering, where the scene is represented through an octree model from which we can obtain a triangle mesh corresponding to a view-dependent LOD. We present ... -
Subdivided linear and curved meshes preserving features of a linear mesh model
(Sandia National Laboratories, 2019)
Text en actes de congrés
Accés obertTo provide straight-edged and curved piece-wise polynomial meshes that target a unique smooth geometry while preserving the sharp features and smooth regions of the model, we propose a new fast curving method based on ... -

Un model d'incertesa fitada per a la propagació i fusió d'informació geomètrica incerta
(Universitat Politècnica de Catalunya, 1996-11-26)
Tesi
Accés obertEn esta tesis se desarrolla un sistema de tratamiento de informaciones geométricas con incertidumbre, basado en la propagación y fusión de regiones elipsoidales. Se adopta un modelo de incertidumbre acotada en el espacio ...
