Least Squares Fitting of Harmonic Functions Based on Radon Projections,. We extend our results to fitting of more general mixed data consisting of both Radon projections and function values. We perform a comparative numerical study of the least-squares approach with two other reconstruction methods for the case of noisy data.

Hermite Interpolation with Rational Splines with Free Weights,uses the linear system as a secondary condition for maximizing the minimum weight. This way allows us to obtain method more open regarding the number of interpolation points. In the third approach, we reduce the number of interpolation points to approximate the values of the function between the interpolation points.

Piecewise Rational Parametrizations of Canal Surfaces,ace correspond to two canal surfaces joined with the same level of continuity.We also describe an algorithm for minimal bi-degree rational parametrizations of patches on canal surfaces, and show how this can be used to parametrize piecewise rational corner and edge blends.

,Bilinear Clifford-Bézier Patches on Isotropic Cyclides,bilinear Clifford-Bézier patches. We derive their implicitization formula and characterize them as patches on special quartic surfaces called .. Finally we present one modeling application with rational surfaces admitting rational offsets.

Representation of Motion Spaces Using Spline Functions and Fourier Series,ave derived an optimization heuristic, which is used to automatically generate the initial motion space. We have evaluated our system by comparison against ground-truth motion data and alternative methods.

,Algorithms and Data Structures for Truncated Hierarchical B–splines, — which is used to represent the nested sequence of subdomains — with a suitable data structure for sparse matrices, we obtain an efficient technique for the construction and evaluation of THB–splines.
