This paper presents two automatic fairing algorithms for parametric C2-continuous bicubic B-
spline surfaces. The fairing method consists of a knot-removal and knot-reinsertion step …

ABSTRACT Bézier curves and surfaces are very important in many areas, especially the
manufacturing and aerospace. Surface inspection through visualisation is required to create …

An automatic and local fairing algorithm for bicubic B-spline surfaces is proposed. A local
fairness criterion selects the knot, where the spline surface has to be faired. A fairing step is …
