  • Skeleton computation of orthogonal polyhedra 

    Martínez Bayona, Jonás; Vigo Anglada, Marc; Pla García, Núria (North Holland, 2011-08)
    Article

    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)
    External research report
    Open Access
    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)
    External research report
    Open Access
    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
    Restricted access - publisher's policy
    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)
    External research report
    Open Access
    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)
    External research report
    Open Access
    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 ...
