{"quality_controlled":"1","day":"01","status":"public","abstract":[{"text":"We present a computational approach for designing CurveUps, curvy shells that form from an initially flat state. They consist of small rigid tiles that are tightly held together by two pre-stretched elastic sheets attached to them. Our method allows the realization of smooth, doubly curved surfaces that can be fabricated as a flat piece. Once released, the restoring forces of the pre-stretched sheets support the object to take shape in 3D. CurveUps are structurally stable in their target configuration. The design process starts with a target surface. Our method generates a tile layout in 2D and optimizes the distribution, shape, and attachment areas of the tiles to obtain a configuration that is fabricable and in which the curved up state closely matches the target. Our approach is based on an efficient approximate model and a local optimization strategy for an otherwise intractable nonlinear optimization problem. We demonstrate the effectiveness of our approach for a wide range of shapes, all realized as physical prototypes.","lang":"eng"}],"intvolume":"        36","date_updated":"2023-09-22T09:49:58Z","ec_funded":1,"related_material":{"record":[{"relation":"dissertation_contains","status":"public","id":"8366"}]},"volume":36,"isi":1,"pubrep_id":"1053","project":[{"_id":"25082902-B435-11E9-9278-68D0E5697425","name":"Soft-bodied intelligence for Manipulation","call_identifier":"H2020","grant_number":"645599"},{"_id":"24F9549A-B435-11E9-9278-68D0E5697425","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling","grant_number":"715767","call_identifier":"H2020"}],"external_id":{"isi":["000406432100032"]},"has_accepted_license":"1","article_processing_charge":"No","date_published":"2017-01-01T00:00:00Z","ddc":["003","004"],"year":"2017","file":[{"creator":"system","file_id":"4811","access_level":"open_access","relation":"main_file","file_size":36159696,"file_name":"IST-2018-1053-v1+1_CurveUp.pdf","date_created":"2018-12-12T10:10:24Z","content_type":"application/pdf","date_updated":"2018-12-12T10:10:24Z"}],"date_created":"2018-12-11T11:49:38Z","alternative_title":["ACM Transactions on Graphics"],"article_number":"64","department":[{"_id":"BeBi"}],"user_id":"c635000d-4b10-11ee-a964-aac5a93f6ac1","publist_id":"6397","author":[{"last_name":"Guseinov","id":"3AB45EE2-F248-11E8-B48F-1D18A9856A87","full_name":"Guseinov, Ruslan","orcid":"0000-0001-9819-5077","first_name":"Ruslan"},{"last_name":"Miguel","first_name":"Eder","full_name":"Miguel, Eder"},{"id":"49876194-F248-11E8-B48F-1D18A9856A87","last_name":"Bickel","first_name":"Bernd","orcid":"0000-0001-6511-9385","full_name":"Bickel, Bernd"}],"file_date_updated":"2018-12-12T10:10:24Z","language":[{"iso":"eng"}],"conference":{"end_date":"2017-08-25","location":"Los Angeles, CA, United States","start_date":"2017-08-19","name":"SIGGRAPH: Special Interest Group on Computer Graphics and Interactive Techniques"},"publication_status":"published","publisher":"ACM","oa":1,"citation":{"chicago":"Guseinov, Ruslan, Eder Miguel, and Bernd Bickel. “CurveUps: Shaping Objects from Flat Plates with Tension-Actuated Curvature,” Vol. 36.
