Multilevel Scattered Data Approximation by Adaptive Domain Decomposition

By Armin Iske, Armin Iske and Jeremy Levesley and Jeremy Levesley


A new multilevel approximation scheme for scattered data is proposed. The scheme relies on an adaptive domain decomposition strategy using quadtree techniques (and their higher-dimensional generalizations). It is shown in the numerical examples that the new method achieves an improvement on the approximation quality of previous well-established multilevel interpolation schemes
