Energy-minimized interpolatory B-spline lofting for sequences of closed contours
Shutao Tang, Zixuan Zhao
B-spline lofting through closed cross-sections is common in reverse engineering, but interpolating each section on its own knot vector can produce an unnecessarily large control ne…

A note on the rectangular Schoenberg-Whitney theorem for clamped B-splines
Shutao Tang, Zixuan Zhao
Wang et al.(Computer-Aided Design 40 (2008) 999-1008) proposed a knot-subsequence characterization of full row rank for rectangular B-spline collocation matrices. We identify an in…
