IGA Using Offset-based Overlapping Domain Parameterizations
Somayeh Kargaran, Bert Jüttler, Thomas Takacs
Isogeometric analysis (IGA) is a numerical method that connects computer-aided design (CAD) with finite element analysis (FEA). In CAD the computational domain is usually represent…
Projective isomorphisms between rational surfaces
Bert Jüttler, Niels Lubbes, Josef Schicho
We present a method for computing projective isomorphisms between rational surfaces that are given in terms of their parametrizations. The main idea is to reduce the computation of…
Fast Approximate Implicitization of Envelope Curves using Chebyshev Polynomials
Oliver J D Barrowclough, Bert Jüttler, Tino Schulz
Consider a rational family of planar rational curves in a certain region of interest. We are interested in finding an approximation to the implicit representation of the envelope.…
Convergence of Tikhonov regularization for solving ill-posed operator equations with solutions defined on surfaces
Guozhi Dong, Bert Juettler, Otmar Scherzer +1
We study Tikhonov regularization for solving ill--posed operator equations where the solutions are functions defined on surfaces. One contribution of this paper is an error analysi…
Computing a Compact Spline Representation of the Medial Axis Transform of a 2D Shape
Yanshu Zhu, Feng Sun, Yi-King Choi +2
We present a full pipeline for computing the medial axis transform of an arbitrary 2D shape. The instability of the medial axis transform is overcome by a pruning algorithm guided…
