Dаtum izdаvаnjа: | 1-дец-2010 | Čаsоpis: | Eurographics Italian Chapter Conference 2010 | Sažetak: | Ascending and descending Morse complexes, defined by the critical points and integral lines of a scalar field f defined on a manifold domain D, induce a subdivision of D into regions of uniform gradient flow, and thus provide a compact description of the morphology of f on D. We propose a dimension-independent representation for the ascending and descending Morse complexes, and we describe a data structure which assumes a discrete representation of the field as a simplicial mesh, that we call the incidence-based data structure. We present algorithms for building such data structure for 2D and 3D scalar fields, which make use of a watershed approach to compute the cells of the Morse decompositions. © The Eurographics Association 2010. | URI: | https://open.uns.ac.rs/handle/123456789/9575 | ISBN: | 9783905673807 | DOI: | 10.2312/LocalChapterEvents/ItalChap/ItalianChapConf2010/103-110 |
