--- res: bibo_abstract: - 'Volumetric light transport is a pervasive physical phenomenon, and therefore its accurate simulation is important for a broad array of disciplines. While suitable mathematical models for computing the transport are now available, obtaining the necessary material parameters needed to drive such simulations is a challenging task: direct measurements of these parameters from material samples are seldom possible. Building on the inverse scattering paradigm, we present a novel measurement approach which indirectly infers the transport parameters from extrinsic observations of multiple-scattered radiance. The novelty of the proposed approach lies in replacing structured illumination with a structured reflector bonded to the sample, and a robust fitting procedure that largely compensates for potential systematic errors in the calibration of the setup. We show the feasibility of our approach by validating simulations of complex 3D compositions of the measured materials against physical prints, using photo-polymer resins. As presented in this paper, our technique yields colorspace data suitable for accurate appearance reproduction in the area of 3D printing. Beyond that, and without fundamental changes to the basic measurement methodology, it could equally well be used to obtain spectral measurements that are useful for other application areas.@eng' bibo_authorlist: - foaf_Person: foaf_givenName: Oskar foaf_name: Elek, Oskar foaf_surname: Elek - foaf_Person: foaf_givenName: Ran foaf_name: Zhang, Ran foaf_surname: Zhang foaf_workInfoHomepage: http://www.librecat.org/personId=4DDBCEB0-F248-11E8-B48F-1D18A9856A87 orcid: 0000-0002-3808-281X - foaf_Person: foaf_givenName: Denis foaf_name: Sumin, Denis foaf_surname: Sumin - foaf_Person: foaf_givenName: Karol foaf_name: Myszkowski, Karol foaf_surname: Myszkowski - 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: Alexander foaf_name: Wilkie, Alexander foaf_surname: Wilkie - foaf_Person: foaf_givenName: Jaroslav foaf_name: Křivánek, Jaroslav foaf_surname: Křivánek - foaf_Person: foaf_givenName: Tim foaf_name: Weyrich, Tim foaf_surname: Weyrich bibo_doi: 10.1364/OE.406095 bibo_issue: '5' bibo_volume: 29 dct_date: 2021^xs_gYear dct_identifier: - UT:000624968100103 dct_isPartOf: - http://id.crossref.org/issn/1094-4087 dct_language: eng dct_publisher: The Optical Society@ dct_title: Robust and practical measurement of volume transport parameters in solid photo-polymer materials for 3D printing@ ...
