Hierarchical bspline refinement

Web1 de ago. de 2024 · The main motivation for hierarchical B-Splines in Isogeometric Analysis is to perform a local refinement that is globally not a tensor product. Compared to standard knot insertion, this allows to increase refinement locality. Moreover, the implementation of hierarchical refinement on existing codes can be facilitated by Bézier extraction. Web22 de set. de 2024 · Other local refinement techniques, such as hierarchical B-splines, are based on subdivision, a technique that can be derived from knot insertion. In the following, we will focus on these hierarchical concepts, since, in the authors’ opinion, they provide a very natural extension to conventional B-splines.
