Local T-spline surface skinning
The Visual Computer, 2012Skinning or lofting remains a challenging problem in computer graphics and free-form surface design. Although it was addressed by many researchers, no sufficiently general solution has been proposed yet. In the interpolating approach, the incompatibility of the input NURBS curves are solved by knot insertion.

An algorithm of determining T-spline classification
Expert Systems with Applications, 2013Abstract T-splines are a new surface modeling technology, whose theoretical framework is not still well founded. Aiming at the problem that how to classify T-splines this paper gives a mathematical analysis, and a sufficient condition of standard T-splines is also given. Then this paper presents an algorithm of determining the T-spline classification,

AS++ T-splines: arbitrary degree, nestedness and approximation
Numerische Mathematik, 2021NURBS (non-uniform rational B-splines) and similar approximation methods such as the so-called T-splines are important methods in the applications of numerical analysis. In this article, T-splines are analysed, and the important properties such as recursive definitions and convergence orders considered. Nestedness features and recursive computation by `

This paper develops the manifold T-splines, which naturally extend the concept and the currently available algorithms/techniques of the popular planar tensor-product NURBS and T-splines to arbitrary manifold domain of any topological type. The key idea is the global conformal parameterization that intuitively induces a tensor-product structure with a ...

Watermarking T-Spline surfaces
2008 11th IEEE International Conference on Communication Technology, 2008This paper proposes two data embedding algorithms for T-spline surfaces, one is suitable for steganography, and the other for robust shape-preserving watermarking. For steganography, we embed data into the points on T-spline surfaces by using constrained optimization method. For robust shape-preserving watermarking, we use the local knot insertion of T-
