1 Mueller, Timothy I.Refinement estimation of B-spline curves and surfacesAn algorithm for refinement estimation for B-spline curves is presented. The algorithm uses approximations to the curvature and arc length to decide how a curve should be refined. The algorithm can also be used to produce isoparametric curves or polygonal tessellations from a Bspline surface.B-spline; Curves; Surfaces; Algorithm; Curvature; Arc length; Isoparametric curves; Polygonal tessellations1988
