Compressing Random Microstructures via Stochastic Wang Tilings
This paper presents a stochastic Wang tiling based technique to compress or
reconstruct disordered microstructures on the basis of given spatial
statistics. Unlike the existing approaches based on a single unit cell, it
utilizes a finite set of tiles assembled by a stochastic tiling algorithm,
thereby allowing to accurately reproduce long-range orientation orders in a
computationally efficient manner. Although the basic features of the method are
demonstrated for a two-dimensional particulate suspension, the present
framework is fully extensible to generic multi-dimensional media.Comment: 4 pages, 6 figures, v2: minor changes as suggested by reviewers, v3:
