Webreﬁnement algorithms. We will need four different data structures: two for tensor-product B-splines, and two for hierarchical B-splines. The ﬁrst two-structures regard the computation of tensor-product B-splines. We assume that, for each level ‘, we have a mesh structure with all the information of the rectilinear grid G‘, and a space http://staff.ustc.edu.cn/~dengjs/files/papers/kcd.pdf
