Hierarchical B-splines on regular triangular partitions
C2interpolation T-splines
On the linear independence of (truncated) hierarchical subdivision splines
TLDR
A catalog of safe subdomains is provided that facilitates the design of domain hierarchies with linearly independent (truncated) hierarchical generating systems.
Modified Bases of PHT-Splines
TLDR
This paper presents a method to modify the basis functions of PHT-splines in the case that the supports of the original truncated basis functions are rectangular domains to overcome the decay problem.
Coefficient-Based Spline Data Reduction by Hierarchical Spaces
TLDR
A coefficient–based least squares spline operator is introduced that does not require any pointwise evaluation to approximate (in a lower dimension spline space) a given bivariate B–spline function.
Foundations of Spline Theory: B-Splines, Spline Approximation, and Hierarchical Refinement
TLDR
This chapter presents an overview of polynomial spline theory, with special emphasis on the B-spline representation, spline approximation properties, and hierarchical spline refinement, and a unified treatment of recent results on hierarchical splines.

Surface fitting with hierarchical splines
TLDR
This work considers the fitting of tensor product parametric spline surfaces to gridded data and uses a hierarchical representation for the surface to improve efficiency and adaptively decompose the fitting process into subproblems involving only a portion of the data.
Adaptive isogeometric analysis by local h-refinement with T-splines
Surface modeling with polynomial splines over hierarchical T-meshes
TLDR
With the method, spline surfaces can be constructed efficiently and adaptively to fit genus-zero meshes after their spherical parameterization is obtained, where only small sized linear systems of equations are involved.
Multiresolution Surface Reconstruction for Hierarchical B-splines
TLDR
The resulting hierarchical surface accurately and economically reproduces the original mesh, is free from excessive undulations in the intermediate levels and produces a multiresolution representation suitable for animation and interactive modelling.

Interpolating and approximating scattered 3D-data with hierarchical tensor product B-splines
