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."}],"oa":1,"date_published":"2017-01-01T00:00:00Z","oa_version":"Submitted Version","conference":{"name":"SIGGRAPH: Special Interest Group on Computer Graphics and Interactive Techniques","location":"Los Angeles, CA, United States","start_date":"2017-08-19","end_date":"2017-08-25"},"department":[{"_id":"BeBi"}],"title":"CurveUps: Shaping objects from flat plates with tension-actuated curvature","article_processing_charge":"No","file_date_updated":"2018-12-12T10:10:24Z","pubrep_id":"1053","language":[{"iso":"eng"}],"date_created":"2018-12-11T11:49:38Z","project":[{"name":"Soft-bodied intelligence for Manipulation","grant_number":"645599","_id":"25082902-B435-11E9-9278-68D0E5697425","call_identifier":"H2020"},{"call_identifier":"H2020","_id":"24F9549A-B435-11E9-9278-68D0E5697425","grant_number":"715767","name":"MATERIALIZABLE: Intelligent fabrication-oriented Computational Design and Modeling"}],"intvolume":"        36","issue":"4","day":"01","ddc":["003","004"],"volume":36,"citation":{"ieee":"R.
