Previous exemplar-based aging And weathering methods have either reused images or sought to replicate observed patterns exactly. We introduce A new approach to exemplar-based modeling that creates weathered patterns on synthetic objects by matching the Statistics of fracture patterns in a photograph. We present a user study to determine which statistics are correlated To visual similarity and how they are perceived by the user. We then describe a revised physically-based fracture Model capable of producing a wide range of crack patterns at interactive rates. We demonstrate how a Bayesian Optimization method can determine the parameters of this model so it can produce a pattern with the same key Statistics as an exemplar. Finally, we present results using our approach and various exemplars to produce a Variety of fracture effects in synthetic renderings of complex environments. The speed of the fracture simulation Allows interactive previews of the fractured results and its application on large scale environments" , "dc.description.sponsorship": "This work is partially supported by the Spanish Ministerio de Ciencia e Innovacion (grant TIN2010-20590-C02-02) and NSF grant NSF-1064412" , "dc.format.mimetype": "application/pdf" , "dc.language.iso": "eng" , "dc.publisher": "Wiley" , "dc.relation": "MICINN/PN 2011-2013/TIN2010-20590-C02-02" , "dc.relation.isformatof": "Reproducció digital del document publicat a: http://dx.doi.org/10.1111/j.1467-8659.2012.03151.x" , "dc.relation.ispartof": "© Computer Graphics Forum, 2012, vol. 31, núm. 4, p. 1547-1556" , "dc.relation.ispartofseries": "Articles publicats (D-IMA)" , "dc.rights": "Tots els drets reservats" , "dc.subject": "Infografia" , "dc.subject": "Computer graphics" , "dc.subject": "Estadística bayesiana" , "dc.subject": "Bayesian statistical decision theory" , "dc.subject": "Simulació per ordinador" , "dc.subject": "Computer simulation" , "dc.title": "Example-based fractured appearance" , "dc.type": "info:eu-repo/semantics/article" , "dc.rights.accessRights": "info:eu-repo/semantics/embargoedAccess" , "dc.embargo.terms": "Cap" , "dc.type.version": "info:eu-repo/semantics/publishedVersion" , "dc.identifier.doi": "http://dx.doi.org/10.1111/j.1467-8659.2012.03151.x" , "dc.identifier.idgrec": "016207" , "dc.contributor.funder": "Ministerio de Ciencia e Innovación (Espanya)" }
