      Company, Pedro; Piquer, Ana; Contero, Manuel; Naya, Ferran Elsevier (2005-12)
      In this work, the background and evolution of three-dimensional reconstruction of line drawings during the last 30 years is discussed. A new general taxonomy is proposed to make apparent and discuss the historical evolution ...
    • 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 ...
