WebThe method uses a hierarchical quad-tree (2D) or octree (3D) structure to efficiently represent the surface details without a significant increase in the number of interior elements. Moreover, the geometry of the surface including normal information can be accurately incorporated in the model by using cubic (or higher-order) splines. WebThe hierarchical B{spline model found applications in data interpolation and approximation [10,11,13], as well as in nite element and isogeometric analysis [1,14,18]. Alternative spline hierarchies were also considered in the literature, see e.g., [9,19]. Kraft’s basis for HB{splines does not possess the partition of unity prop-
