Axioms, 2015 Conventional splines offer powerful means for modeling surfaces and volumes in three-dimensional Euclidean space. A one-dimensional quaternion spline has been applied for animation purpose, where the splines are defined to model a one-dimensional submanifold in the three-dimensional Lie group. Given two surfaces, all of the diffeomorphisms between them

THB-splines: The truncated basis for hierarchical splines [PDF]
Computer Aided Geometric Design, 2012 The construction of classical hierarchical B-splines can be suitably modified in order to define locally supported basis functions that form a partition of unity. The authors show that this property can be obtained by reducing the support of basis functions defined on coarse grids, according to finer levels in the hierarchy of splines.

Scientific Visualization Conference (dagstuhl '97), 1997 We describe an alternative way of constructing interpolating B-spline curves, surfaces or volumes in Fourier space which can be used for visualization. In our approach the interpolation problem is considered from a signal processing point of view and is reduced to finding an inverse B-spline filter sequence.

Variable degree polynomial splines are Chebyshev splines [PDF]
Advances in Computational Mathematics, 2011 Variable degree polynomial (VDP) splines have recently proved themselves as a valuable tool in obtaining shape preserving approximations. However, some usual properties which one would expect of a spline space in order to be useful in geometric modeling, do not follow easily from their definition.

Parametrization and penalties in spline models with an application to survival analysis [PDF]
, 2008 A simple parametrization, built from the definition of cubic splines, is shown to facilitate the implementation and interpretation of penalized spline models, whatever configuration of knots is used.

Polynomial splines as examples of Chebyshevian splines [PDF]
Numerical Algorithms, 2012 Spaces of geometrically continuous (piecewise defined) functions are considered in this paper. Such functions in use for approximation purposes of all sorts may be piecewise polynomials or more generally coming from extended Chebyshev spaces. The latter are natural generalisations of polynomial spline structures.
