    • Regular triangulations of dynamic sets of points 

      Vigo Anglada, Marc; Pla García, Núria (2000-10)
      Report de recerca
      Accés obert
      The 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 ...
    • Skeletal representations of orthogonal shapes 

      Martínez Bayona, Jonás; Pla García, Núria; Vigo Anglada, Marc (2013-07-01)
      Article
      Accés restringit per política de l'editorial
      Orthogonal shapes are polygons orpolyhedra enclosed byaxis-aligned edges orfaces, respectively. Inthis paper wepresent two skeletal representatio nsoforthogonal shapes: the cube skeleton and a family ofskeletal represe ...
    • Skeletal representations of orthogonal shapes 

      Martínez Bayona, Jonás; Pla García, Núria; Vigo Anglada, Marc (2012)
      Report de recerca
      Accés obert
      In this paper we present two skeletal representations applied to orthogonal shapes of R^n : the cube axis and a family of skeletal representations provided by the scale cube axis. Orthogonal shapes are a subset of polytopes, ...
    • Skeleton computation of an image using a geometric approach 

      Martínez Bayona, Jonàs; Vigo Anglada, Marc; Pla García, Núria; Ayala Vallespí, M. Dolors (2010-03)
      Report de recerca
      Accés obert
      In this work we develop two algorithms to compute the skeleton of a binary 2D images. Both algorithms follow a geometric approach and work directly with the boundary of the image wich is an orthogonal polygon (OP). One of ...

    • Skeleton computation of orthogonal polyhedra 

      Martínez Bayona, Jonás; Vigo Anglada, Marc; Pla García, Núria (North Holland, 2011-08)
      Article
      Accés restringit per política de l'editorial
      Skeletons are powerful geometric abstractions that provide useful representations for a number of geometric operations. The straight skeleton has a lower combinatorial complexity compared with the medial axis. Moreover, while ...
    • Splat representation of parametric surfaces 

      Ayala Vallespí, M. Dolors; Pla García, Núria; Vigo Anglada, Marc (2005-09)
      Report de recerca
      Accés obert
      Point-based geometry representations and their splat-based generalizations have become a suitable technique both for modeling and rendering complex 3D shapes. So, it seems interesting to convert other kind of models to ...
    • Surface fairing for ship hull design application. 

      Brunet Crosa, Pere; Vinacua Pla, Álvaro; Vivo Lorenzo, Manuel; Pla García, Núria; Rodríguez, A (1998-06)
      Report de recerca
      Accés obert
      This paper describes the design and implementation of a fairing module for a ship hull design application. This module is part of a large project on ship design, including facilities for piping, hull design and virtual ...
    • The three-dimensional cube and scale cube skeleton 

      Martínez Bayona, Jonàs; Pla García, Núria; Vigo Anglada, Marc (Springer, 2014)
      Article
      Accés restringit per política de l'editorial
      The recently introduced cube and scale cube skeleton of Martínez et al. (Graph Models 75:189–207, 2013) are a new type of skeletal representations for polygons or polyhedra enclosed by axis-aligned edges or faces. In this ...
    • Towards free form surfaces 

      Cotrina Navau, Josep; Pla García, Núria; Vigo Anglada, Marc (2001-03)
      Report de recerca
      Accés obert
      A theoretical approach to construct free form surfaces is presented. We develop the conceps that arise when a free form surface is generated by tracing a mesh, using differentiable manifold theory, and generalizing the ...
    • Two triangulations methods based on edge refinement 

      Ayala Vallespí, M. Dolors; Pla García, Núria; Vigo Anglada, Marc (2003-03)
      Report de recerca
      Accés obert
      In this paper two curvature adaptive methods of surface triangulation are presented. Both methods are based on edge refinement to obtain a triangulation compatible with the curvature requirements. The first method applies ...
