A practical and robust method to compute the boundary of three-dimensional axis-aligned boxes
López Monterde, Daniel; Martínez Bayona, Jonas; Vigo Anglada, Marc; Pla García, Núria (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
Vigo Anglada, Marc (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
Vigo Anglada, Marc (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
Vigo Anglada, Marc; Pla García, Núria; Brunet Crosa, Pere (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 ... -

Diagrames de Voronoi i grafs de Delaunay de distancies amb pesos i de distàncies el·líptiques
Vigo Anglada, Marc (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
Vigo Anglada, Marc; Pla García, Núria; Brunet Crosa, Pere (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 ... -

From degenerate patches to triangular and trimmed patches
Vigo Anglada, Marc; Pla García, Núria; Brunet Crosa, Pere (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 ... -

Geometric objects in Blender 2.32
Vigo Anglada, Marc (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
Gracia, Manuel de; Vigo Anglada, Marc (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 ... -
