A practical and robust method to compute the boundary of three-dimensional axis-aligned boxes
(2013)
Report de recerca
Accés obertThe union of axis-aligned boxes results in a constrained structure that is advantageous for solving certain geometrical problems. A widely used scheme for solid modelling systems is the boundary representation (Brep). We ... -

An incremental algorithm based on edge swapping for constructing restricted Delaunay triangulations
(1995-12)
Report de recerca
Accés obertThis work presents an algorithm that given a generalized planar graph obtains its Constrained Delaunay Triangulation (CDT). The proposed method works incrementally based in two procedures, one that inserts a new point in ... -

Computing directional constrained Delaunay triangulations
(1998-03)
Report de recerca
Accés obertThis work presents two generalizations of the algorithm for obtaining a constrained Delaunay triangulation of a general planar graph presented in [Vig97] and [Vig95]. While the first generalization works with ... -
Curvature adaptive triangulations of surfaces
(2000-03)
Report de recerca
Accés obertMany application areas in CAD/CAM are concerned with triangulation of surfaces, and require an error bounded approximation of a parametric surface model. In this paper we present an overview of the authors results on ... -

Report de recerca
Accés obertEn este trabajo se presenta una aplicacion CAE para el diseno de circuitos de ventilacion. En ella se han desarrollado aspectos de diseno del modelo, de la interaccion con el usuario y de simulacion del comportamiento ... -
Diagrames de Voronoi i grafs de Delaunay de distancies amb pesos i de distàncies el·líptiques
(1999-12-01)
Report de recerca
Accés obertThis work studies the feasibility of a constrained Delaunay triangulation of a set of points on the plane including directionality pointed by the ellipses associated to the points. Generalizations of the Voronoi diagram ... -
Directional adaptive surface triangulation
(1999-02)
Article
Accés restringit per política de l'editorialSeveral CAD applications require a surface model of the modeled object consisting of a mesh of triangular facets. In this paper, a new algorithm for triangulation of trimmed surfaces is presented. The algorithm generates ... -
Efficient algorithms for boundary extraction of 2D and 3D orthogonal pseudomanifolds
(2012)
Article
Accés restringit per política de l'editorialIn this paper we present algorithms to extract the boundary representation of orthogonal polygons and polyhedra, either manifold or pseudomanifold. The algorithms we develop reconstruct not only the polygons of the boundaries ... -

From degenerate patches to triangular and trimmed patches
(1995-03)
Report de recerca
Accés obertCAD systems are usually based on a tensor product representation of free form surfaces. Trimmed patches provide a reasonable solution for the representation of general topologies, provided that the gap between equivalent ... -
Funciones en el modelado de solidos y paradigmas de diseño
(2001-10)
Report de recerca
Accés obertEn este artículo se describen y analizan las diferentes funciones de modelado de sólidos más comunes que ofrecen los actuales sistemas de CAD. Se explican también las limitaciones e inconsistencias a qué pueden dar ... -
Geometric objects in Blender 2.32
(2004-05)
Report de recerca
Accés obertThe aim of this document is to explore the way that Blender 2.32 stores the information for modeling static scenes. First, the conceptual model the system uses to store geometric objects is explained, guiding the user to ... -
La modularidad de la mente: origen y transformación de una metáfora
(2001-05)
Report de recerca
Accés obertIn this work we try to make clear the actual reference of the modular hypothesis of the mind, and the epistemological and ontological relevance of the metaphor. We also make a critical evaluation of the contribution of ... -
Multisided patches
(2004-06)
Report de recerca
Accés obertWe present a method to construct a patch of parametric surface of degree k + 1 that lls a n-sided hole, with n bigger than 2, and whose boundary coincides with a B-Spline, thus, the resulting patch can be easily connected ... -
N-sided patches with B-spline boundaries
(2001-12)
Report de recerca
Accés obertWe present a method to construct a patch of parametric surface of degree k+1 that fills a n-sided hole, with bigger than 2, and whose boundary coincides with a B-Spline, thus, the resulting patch can be easily connected ... -

Regular triangulations of dynamic sets of points
(2000-10)
Report de recerca
Accés obertThe Delaunay triangulations of a set of points are a class of triangulations which play an important role in a variety of different disciplines of science. Regular triangulations are a generalization of Delaunay ...
