An efficient data structure for calculation of unstructured T-spline surfaces
Visual Computing for Industry, Biomedicine, and Art, 2019 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 ...

Industrial Robot Contouring Control Based on Non-Uniform Rational B-Spline Curve
Symmetry, 2022 This paper presents a novel algorithm about the industrial robot contouring control based on the NURBS (non-uniform rational B-spline) curve. First, aiming at the error between the industrial robot’s actual trajectory and the desired trajectory, the contour error is proposed as the trajectory evaluation index, and the estimation algorithm of contour ...
