A local Hermite interpolation scheme with PH quintic splines for 3D data streams
Carlotta Giannelli, Lorenzo Sacco, Alessandra Sestini
The construction of smooth spatial paths with Pythagorean-hodograph (PH) quintic spline biarcs is proposed. To facilitate real-time computations of PH quintic splines, an eff…

THB-spline approximations for turbine blade design with local B-spline approximations
Cesare Bracco, Carlotta Giannelli, David Grossmann +3
We consider two-stage scattered data fitting with truncated hierarchical B-splines (THB-splines) for the adaptive reconstruction of industrial models. The first stage of the scheme…
