![]() | Lyche, Tom | A note on the Oslo algorithm | The Oslo algorithm is a recursive method for updating the B-spline representation of a curve or tensor product surface when extra knots are added. In the present note the derivation of this method is simplified. | Oslo algorithm; B-spline; Curve product surface; Tensor product surface | 1987 |

![]() | Mueller, Timothy I. | Refinement estimation of B-spline curves and surfaces | An 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 tessellations | 1988 |
