Classic tools for editing translucent appearance, based on the use of sliders to tune a number of parameters, are challenging for non‐expert users: These parameters have a highly non‐linear effect on appearance, and exhibit complex interplay and similarity relations between them. Instead, we pose editing as a navigation task in a low‐dimensional space of appearances, which abstracts the user from the underlying optical parameters. To achieve this, we build a low‐dimensional continuous manifold of translucent appearance that correlates with how humans perceive this type of materials. We first analyze the correlation of different distance metrics in image space with human perception. We select the best‐performing metric to build a low‐dimensional manifold, which can be used to navigate the space of translucent appearance. To evaluate the validity of our proposed manifold within its intended application scenario, we build an editing interface that leverages the manifold, and relies on image navigation plus a fine‐tuning step to edit appearance. We compare our intuitive interface to a traditional, slider‐based one in a user study, demonstrating its effectiveness and superior performance when editing translucent objects. info:eu-repo/grantAgreement/EC/H2020/956585/EU/Predictive Rendering In Manufacture and Engineering/PRIME This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 956585-PRIME info:eu-repo/grantAgreement/ES/MICINN/PID2022-141766OB-I00 info:eu-repo/semantics/openAccess by-nc https://creativecommons.org/licenses/by-nc/4.0/deed.es 2.9 2024 COMPUTER SCIENCE, SOFTWARE ENGINEERING 49 / 129 = 0.38 2024 Q2 T2 0.788 2024 Computer Graphics and Computer-Aided Design 2024 Q1 Computer Networks and Communications 2024 Q2 6.0 2024 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Masia, Belen Universidad de Zaragoza (orcid)0000-0003-0060-7278 Jarabo, Adrian (orcid)0000-0001-9000-0466 5007 570 Universidad de Zaragoza Dpto.
