A Review of T-spline Surfaces

Recent Patents on Engineering, 2022
Background: Curved modeling technology originated from the geometric lofting and design of aircrafts, automobiles and ships. The control points of the traditional B-spline mesh should be placed regularly in whole rows and columns. A T-spline surface is a B-spline surface that allows T-junctions.

Local T-spline surface skinning

The Visual Computer, 2012
Skinning 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, 2013
Abstract 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,

Manifold T-Spline

2006
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 ...

AS++ T-splines: arbitrary degree, nestedness and approximation

Numerische Mathematik, 2021
NURBS (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 `

Watermarking T-Spline surfaces

2008 11th IEEE International Conference on Communication Technology, 2008
This 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-
