WebThey call such hierarchical B-splines as truncated hierarchical B-splines (THB-splines), which are non-negative, locally supported, linearly independent and form a partition of unity, and allow an effective local control of refinement. There are also several other kinds of local refinement splines developed in the past decade besides HB-splines.
