插值细分方案是细化规则,其通过使用相邻点的线性组合插入对应于中间点的值来细化数据。在这里,我们只考虑规则网格的细化,这在单变量的情况下(细分曲线生成)是均匀分布的点上的真实的线,并在双变量的情况下(细分曲面生成)是正方形网格或定期三角剖分。
Interpolatory subdivision schemes are refinement rules, which refine data by inserting values corresponding to intermediate points, using linear combinations of neighbouring points. Here we consider only refinements of regular meshes, which in the univariate case (subdivision for curve generation) are uniformly distributed points on the real line, and in the bivariate case (subdivision for surface generation) are either square grids or regular triangulations.
