    • Changing Tangent and Curvature Data of B-splines via Knot Manipulation 

      Béla, Szilvia B.-S; Szilvási-Nagy, Márta (2016)
      Modifications of B-spline knot values change the parametrization and influence the shape of B-spline curves. Via these computations one can modify B-spline data (derivative, curvature value at a curve point, some points ...
