• closedAccess   A new algorithm for finding faces in wireframes 

      Varley, Peter Ashley Clifford; Company, Pedro Elsevier (2010)
      The problem of identifying the topology implied by wireframe drawings of polyhedral objects requires the identification of face loops, loops of edges which correspond to a face in the object the drawing portrays. In this ...
    • openAccess   An optimisation-based reconstruction engine for 3D modelling by sketching 

      Company, Pedro; Contero, Manuel; Conesa, Julián; Piquer, Ana Elsevier (2004-12)
      An engine that automatically reconstructs a large variety of polyhedral, origami and wire-frame objects from single-view sketched drawings generated in a calligraphic interface is presented. The engine has two stages. An ...
    • openAccess   Comments on "what the back of the object looks like: 3D reconstruction from line drawings without hidden lines" 

      Varley, Peter Ashley Clifford Institute of Electrical and Electronics Engineers (2009-08)
      I comment on a paper describing a method for deducing the hidden topology of an object portrayed in a 2D natural line drawing. The principal problem with this paper is that it cannot be considered an advance on (or even ...
