Locally Refined T‐splines [PDF]
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.

Linear Independence of T-Spline Blending Functions of Degree One for Isogeometric Analysis
Linear independence of the blending functions is a necessary requirement for T-spline in isogeometric analysis. The main work in this paper focuses on the analysis about T-splines of degree one, we demonstrate that all the blending functions of such T ...

Myometrial invasion (MI) is a parameter currently used in transvaginal ultrasound (TVS) in endometrial cancer (EC) to determine local staging; however, without molecular diagnostics, it is insufficient for the selection of high-risk cases, i.e., those ...

An efficient data structure for calculation of unstructured T-spline surfaces
To overcome the topological constraints of non-uniform rational B-splines, T-splines have been proposed to define the freeform surfaces. The introduction of T-junctions and extraordinary points makes it possible to represent arbitrarily shaped models by ...

The Analysis of T-spline Fairness [PDF]
AbstractThe fairness of curves and surfaces has been used in the shape design of industrial products more and more widely. With the wide applications of T-splines in the surface modeling, this paper analyzes the fairness of T-splines and gives some fairness properties of standard T-splines and semi-standard T-splines.

Effective T-spline representation for VRML
Less control points are needed to represent a shape in T-Splines compared to NURBS and subsequently less time is spent in modeling. While getting more and more accepted by commercial software, T-splines, however, are yet part of VRML/X3D. The T-spline VRML is proposed in this work. An effective data structure is designed for T-splines to support online
