Stitching Locally Fitted T-Splines for Fast Fitting of Large-Scale Freeform Point Clouds [PDF]
Sensors, 2023 Parametric splines are popular tools for precision optical metrology of complex freeform surfaces. However, as a promising topologically unconstrained solution, existing T-spline fitting techniques, such as improved global fitting, local fitting, and ...

Globally structured 3D Analysis-suitable T-splines: definition, linear independence and m-graded local refinement [PDF]
Computer Methods in Applied Mechanics and Engineering, 2016 This paper addresses the linear independence of T-splines that correspond to refinements of three-dimensional tensor-product meshes. We give an abstract definition of analysis-suitability, and prove that it is equivalent to dual-compatibility, wich ...

Locally Refined T‐splines [PDF]
International Journal for Numerical Methods in Engineering, 2018 SummaryWe extend Locally Refined (LR) B‐splines to LR T‐splines within the Bézier extraction framework. This discretization technique combines the advantages of T‐splines to model the geometry of engineering objects exactly with the ability to flexibly carry out local mesh refinement.
