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.","lang":"eng"}],"department":[{"_id":"BeBi"}],"day":"04","file":[{"date_created":"2019-07-24T07:36:08Z","file_size":10109800,"file_id":"6669","date_updated":"2020-07-14T12:47:36Z","file_name":"2019_ACM_Sumin_AuthorVersion.pdf","access_level":"open_access","creator":"dernst","content_type":"application/pdf","relation":"main_file","checksum":"43c2019d6b48ed9c56e31686c4c2d1f5"},{"relation":"supplementary_material","checksum":"f80f365a04e35855fa467ea7ab26b16c","content_type":"application/zip","file_name":"sumin19geometry-aware-suppl.zip","creator":"dernst","access_level":"open_access","date_updated":"2020-07-14T12:47:36Z","file_id":"6938","file_size":11051245,"date_created":"2019-10-11T06:51:07Z"}],"type":"journal_article","date_updated":"2023-08-29T06:40:49Z","month":"07","article_processing_charge":"No","isi":1,"file_date_updated":"2020-07-14T12:47:36Z","ddc":["000"],"project":[{"call_identifier":"H2020","grant_number":"642841","_id":"2508E324-B435-11E9-9278-68D0E5697425","name":"Distributed 3D Object Design"},{"call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767"}],"volume":38,"intvolume":"        38","year":"2019","ec_funded":1,"citation":{"short":"D.
