--- res: bibo_abstract: - "Commercially available full-color 3D printing allows for detailed control of material deposition in a volume, but an exact reproduction of a target surface appearance is hampered by the strong subsurface scattering that causes nontrivial volumetric cross-talk at the print surface. Previous work showed how an iterative optimization scheme based on accumulating absorptive materials at the surface can be used to find a volumetric distribution of print materials that closely approximates a given target appearance.\r\n\r\nIn this work, we first revisit the assumption that pushing the absorptive materials to the surface results in minimal volumetric cross-talk. We design a full-fledged optimization on a small domain for this task and confirm this previously reported heuristic. Then, we extend the above approach that is critically limited to color reproduction on planar surfaces, to arbitrary 3D shapes. Our method enables high-fidelity color texture reproduction on 3D prints by effectively compensating for internal light scattering within arbitrarily shaped objects. In addition, we propose a content-aware gamut mapping that significantly improves color reproduction for the pathological case of thin geometric features. Using a wide range of sample objects with complex textures and geometries, we demonstrate color reproduction whose fidelity is superior to state-of-the-art drivers for color 3D printers.@eng" bibo_authorlist: - foaf_Person: foaf_givenName: Denis foaf_name: Sumin, Denis foaf_surname: Sumin - foaf_Person: foaf_givenName: Tim foaf_name: Weyrich, Tim foaf_surname: Weyrich - foaf_Person: foaf_givenName: Tobias foaf_name: Rittig, Tobias foaf_surname: Rittig - foaf_Person: foaf_givenName: Vahid foaf_name: Babaei, Vahid foaf_surname: Babaei - foaf_Person: foaf_givenName: Thomas foaf_name: Nindel, Thomas foaf_surname: Nindel - foaf_Person: foaf_givenName: Alexander foaf_name: Wilkie, Alexander foaf_surname: Wilkie - foaf_Person: foaf_givenName: Piotr foaf_name: Didyk, Piotr foaf_surname: Didyk - foaf_Person: foaf_givenName: Bernd foaf_name: Bickel, Bernd foaf_surname: Bickel foaf_workInfoHomepage: http://www.librecat.org/personId=49876194-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0001-6511-9385 - foaf_Person: foaf_givenName: Jaroslav foaf_name: Křivánek, Jaroslav foaf_surname: Křivánek - foaf_Person: foaf_givenName: Karol foaf_name: Myszkowski, Karol foaf_surname: Myszkowski bibo_doi: 10.1145/3306346.3322992 bibo_issue: '4' bibo_volume: 38 dct_date: 2019^xs_gYear dct_identifier: - UT:000475740600085 dct_isPartOf: - http://id.crossref.org/issn/0730-0301 dct_language: eng dct_publisher: ACM@ dct_title: Geometry-aware scattering compensation for 3D printing@ ...
