Quadratic-Attraction Subdivision determines the completion of a quadratic expansion at the central point to attract a differentiable subdivision surface towards bounded curvature, with good shape also in-the-large.CCS Concepts: Computing methodologies -> Parametric curve and surface models; Mathematics of computing -> Continuous functionsComputing methodologiesParametric curve and surface modelsMathematics of computingContinuous functions10.1111/cgf.1490011 pages
