An Isogeometric Analysis Approach to Kinematics of Spatial Rigid Multibody Systems with Imperfect Joints [PDF]
Modeling, Identification and Control, 2020 This paper proposes a novel generic methodology for kinematics of spatial rigid-multibody systems with and without lubricated joints. In this method CAD surface representations in the form of non-uniform rational B-splines (NURBS) are used to address the

A discrete methodology for controlling the sign of curvature and torsion for NURBS [PDF]
, 2009 This paper develops a discrete methodology for approximating the so-called convex domain of a NURBS curve, namely the domain in the ambient space, where a user-specified control point is free to move so that the curvature and torsion retains its sign ...

Texture Mapping on NURBS Surface
Proceedings, 2018 Texture mapping allows high resolution details over 3D surfaces. Nevertheless, texture mapping has a number of unresolved problems such as distortion, boundary between textures or filtering. On the other hand, NURBS surfaces are usually decomposed into a

Fitting and fairing quad-meshes by matrix weighted NURBS surfaces(矩阵权NURBS曲面的拟合与光顺)
Zhejiang Daxue xuebao. Lixue ban, 2023 介绍了利用矩阵权非均匀有理 B-spline（non-uniform rational B-spline，NURBS）曲面拟合与光顺带法向的网格数据。通过输入带法向的规则四边形网格，以网格的顶点为曲面的控制顶点，用法向信息计算每个控制顶点对应的矩阵权，构造矩阵权NURBS曲面。与传统NURBS曲面相比，矩阵权NURBS曲面具有拟柱面精度，当数据均匀采样自光滑曲面时，构造的矩阵权NURBS曲面具有较好的光顺性且能很好地拟合网格模型；当输入的网格数据掺杂噪声时 ...
