• openAccess   CSG Feature Trees from Engineering Sketches of Polyhedral Shapes 

      Plumed, Raquel; Varley, Peter Ashley Clifford; Company, Pedro Eric Galin and Michael Wand (2014)
      We investigate the problem of determining design intent from engineering sketches: what did the designer have in mind when sketching a component? Specifically, we consider the unidirectional reverse mapping from form ...
    • openAccess   Perimeter detection in sketched drawings of polyhedral shapes 

      Company, Pedro; Varley, Peter Ashley Clifford; Plumed, Raquel The Eurographics Association (2017)
      This paper describes a new “envelope” approach for detecting object perimeters in line-drawings vectorised from sketches of polyhedral objects. Existing approaches for extracting contours from digital images are unsuitable ...
