• Data-driven quasi-interpolant spline surfaces for point cloud approximation 

      Raffo, Andrea; Biasotti, Silvia (Peer reviewed; Journal article, 2020)
      In this paper we investigate a local surface approximation, the Weighted Quasi Interpolant Spline Approximation (wQISA), specifically designed for large and noisy point clouds. We briefly describe the properties of the ...

    • Reverse engineering of CAD models via clustering and approximate implicitization 

      Raffo, Andrea; Barrowclough, Oliver Joseph David; Muntingh, Agnar Georg Peder (Peer reviewed; Journal article, 2020)
      In applications like computer aided design, geometric models are often represented numerically as polynomial splines or NURBS, even when they originate from primitive geometry. For purposes such as redesign and isogeometric ...
    • Weighted quasi-interpolant spline approximations: Properties and applications 

      Raffo, Andrea; Biasotti, Silvia (Peer reviewed; Journal article, 2020)
      Continuous representations are fundamental for modeling sampled data and performing computations and numerical simulations directly on the model or its elements. To effectively and efficiently address the approximation of ...
